Hello. I need help opening the service menu on a Panasonic TC-59R62
Its an old CRT with bad overscan. The top left of the screen is cut out and I need to adjust it. Ive tried multiple methods online ie, holding volume down on the TV then pressing recall (with the 30m timer as well). Nothing I have tried has been able to bring up the menu if there's one at all.
Or is there an adapter I could use to fix this? Trying to use the TV for old retro games but again the top left of the screen is cut out and cant see anything displayed there.

Sooo... I have an interesting victim today. Our special on the menu is a APC Smart UPS SUA1500. Looks like it's got Alzheimer or isn't smart anymore (dead, dumb as f@ck), but at the same time it isn't.
Battery is about a year old and they are good at a resting voltage of 26.5VDC. If I press the on button for 3 seconds it does turn the inverter on and I get 120VAC no problem at the back and the battery shows full. So it isn't the battery. It also charges the battery no problem when plugged in add that as a twist!
However if I plug it in with the battery attached it won't...

I'm not sure if I am posting this in the right spot, I don't have any question or anything specific to one board. I am *kinda* starting out with this kind of work. I have been IT in one role or another for my job the last 30 years, and I am familiar enough with basic board stuff generally speaking. So, I dunno for example if someone told me to find a uart header, or flash some generic tsop8 something, etc I understand that kind of stuff. Point being, I'm not 100% clueless. I just don't have the specific knowledge when it comes to some of these more advanced repairs. I actually have spent the last...

Hi everyone! First time here, glad I found this site.

I have a problem with my iMac which suddenly shutdown during a macos update. It turns on to a black screen, the fan is running, off-sequence LED (1-off, 2-3on, 4-5off). Tried replacing the PSU with known working PSU but that didn't fix it. Tried to swap RAM but that didn't fix. I'm now trying to find schematics for my board (820-01310-A is the number printed on it) to better understand the power rails. It seems like it's an unusual configuration, I have the i9 3.6ghz with Vega 48.

Also, someone told me it could be...

Hello everybody☺️ I am glad to be here and looking forward to a good discussion.

First of all, I am new here. Therefore I will shortly introduce myself.
I am Nico and currently I study Physics.
In my freetime I like to build and repair stuff. Especially big battery's.

A few years ago I got myself an electric unicycle, monowheel or however you call that.
The battery bms was broken so I replaced and resolder that. Nothing big.
I used this thing for some years and had a lot of fun. Unfortunately I used it last time in heavy rain. Usually everything...

Hello, on a step motor driver board,
I have found damaged ULN2003 manufactured by ST as package SOP 16 (narrow). Now I have possibility to order get delivered very fast the following mark: ULN2003AFWG,
I'm not really sure if this is equivalent IC.
On the original I can (hardly) read the following data: G001284, and on this replacement IC there is also this: [B]024826[/B]

So, are these two ICs equivalent or not? First one is made by ST and second one by Toshiba. Based on the available manuals and schematics it should be 100% match.
What I need to pay attention...

I have been searching for some days in different places, archives, forums... no way. Nobody seems to have the schematics for the Mac Mini 2006 (The core duo version, ma608ll/a).

That year there were two mac minis, but I think they share the same motherboard.

Could someone point me in the right direction? Thanks in advance!!! This forum is my last resort

My parents' Panasonic P42S30 died recently, and they asked me to have a look at it. I was able to identify the SN-board as the culprit, as it was shorted. After removing Q401, Q402, Q421 and Q422 the short was gone, so I replaced these components and that got the TV working again. However, when testing the tv a bit, I noticed quite bad pinkish sparkles on some colors. For instance the greyish bar on this forum seems to trigger it quite badly. I made a fullscreen test picture with only that color, with the below result.

I am facing a strange issue, I don't have any sound over my internal MacBook speakers and also the video won't start. If I change to my head speaker or via HDMI (speaker on my external Display) the sound works over the head speaker or Display and also the video starts (ex. youtube).

All happened after the battery ran out of power overall several days when I was on vacation.

I tried to remove the battery and then reconnected the battery, and then the MacBook Pro 14 2021 won't accept any power from my power socket. Then I removed one speaker, connected again the battery...

Hi there! One friend called to say his fancoill (used for a main access cold Air courtain) controller caught fire, and asking if I could recover the half burnt board
He said the design was too bad as this thing was probably designed for hot water only, as the board was places right underneath the condenser radiators
I found some burnt traces and after a quick Google search for the board name (Pwr-05v-w) I could see an image of the original I was able to find where the original traces were going
The scheme seems simple, from what I understand mains gets into the while 3 lead...

Howdy all I have a 90uF Capacitor 200/275 VRMS and measured the ESR . Reading says 00.3 Ohms and about 1/2 a second later 00,0 and says low ESR (Really No Kidding).
I have checked it on the multimeter and reading is 94.7uF well within soec as ir has a 25% tolerance on it.
Can anyone advise me is this capacitor likely to fail in the near future or still good to use.

Ok so here's the story. I was watching tv one day when all of a sudden I heard a pop from the back of the tv set and rushed to unplug the set. By this time the tv already had smoke coming out the back. It was not storming or inclement weather that day to cause a power surge to the best of my abilities. When I opened the tv up, I found that the three capacitors on the psu (highlighted in red) were all bulging and looked they had exploded. I replaced all of them right away and when I went to start up the tv after the "fix" it started just showing the flashing vizio logo as soon as power...

I have tried basic troubleshooting steps, remove the battery, disconnect the display, remove the RAM card, connect an external HDMI display. The behavior is always the same, the laptop turns on, shows the keyboard backlight, starts the fan, then it turns off the fan/light briefly, it does this sequence multiple times, let's say 6-7 times.

Order my parts from mobilesentrix.com and iPhone batteries have been excellent. Recently got 3x bad A1534 (2015) batteries. All would work until ~30-40+% and drop to < 10% instantly. Typical sign of cheap batteries.

Perhaps the less popular A1534 model's aftermarket batteries are more source limited. Just find it surprising quality from mobilesentrix (usually fairly high quality aftermarket parts) have been so poor.

So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on...

The issue with this video card is the HDMI port. Specifically on pin 19 (Diode checks on all other pins are normal). When i do a diode check on it from the pin on the board itself, I have nothing. There is also no short on the pin. Resistance reads about 200k. Normally on any HDMI pin 19 I would expect some voltage drop anywhere from .5v to 1.2v but here, I have nothing. The card is operational and can be used via the displayPort ports, but not through the HDMI. Attached you will find the pdf schematics for the card on page 22. I have verified that all of the resistors on this line before the...

[inck243]

Thanks for any help. The board version is DAZAARMB6E0 REV: E. The bios chip is winbond 25Q64JVSIQ1736. W25Q64JV is not available in AsProgrammer -- only BV CV FV or FW_1.8c. The chip won't interface with asProgrammer and a CH341A. When I have this chip on the board, the laptop will not post but when I plug it in to power, the blue LED lights up, also the orange when the battery is connected. When I push the power on button, keyboard backlight turns on and the fan starts briefely then turns off. But I can't do anything to program this bios chip so I bought another one.

[pc_okay]

Hello,

I have a messed up motherboard asus GL504GS 2.1.
Someone break pin of fan connector and 12V pin touch FAN1_PWM pin, and of course turn off pc..

Now pins are repaired but, still, the 3v/5v chip overheat, and FAN1_PWM is 12 ohm to ground.

FAN1_PWM is directly connected to IT8225VG-128.... There is just a condo on the way and it's okay.

So my deduction is IT8225VG-128 is dead and pull to much voltage from 3V linear of 3v/5v chip. (i already change 3v/5v chip for fun, and same problem of course...)
Can you confirm my guess?...

Hi guys,

I have a Mac air A1466 2015 8GB, it came dead, no light on charger, nothing. The current on the psu was about 45mah. After reflowing the SMC, not I get light on the charger, its charging the battery, cpu has 1,8V, ram vas voltage, ssd too. So when pressing the power button with the battery in the current jumps to about 1,8A, without the battery, when its off, its about 40mah, pressing the power goes to agout 500mah, cpu gets warm, ram too, but no fan spin and no image. I know its coming on because I see the current change on the psu.

The cpu has about 6,8ohm,...

Hello, today I'm working on this lovely MSI Raider GE75 gaming laptop which I bought to flip. Unfortunately, I believe the CPU is toast but I wanted a second opinion before I chucked it into my spare parts bin.

I do not have the original 230w charger, but I have a Dell 180w which was sold with the device and reportedly "worked fine for them".

[kurtspirit]

Good morning,
I have a problem with a Macbook A2141 with the audio jack port. Sound only comes out from one side (left). The right one just emits a kind of crackling sound.

I changed the jack ports twice to be sure that it was not caused by a defective part, but the result was the same.

I have the impression that it could be an audio filter or component but I am unable to locate the affected part on the motherboard.
Have you ever encountered a similar problem and can you help me find the filters, if they exist, on the map please?

Thanks in advance...

Hello
Mother called and said TV turns off after switching on. So after turning on Philips logo shows and probably 10-20 seconds image disappears, sat receiver is connected and sound is heard from source. So I turned on my phones light and I can see the image it seems backlight was off after some time. I dis assembled the cover hoping to see a distinc cap blown or leakage. Here are photos I took (I was after 22:00 pm and maybe some of them are dark). Should I order and change caps on the power circuit or what would you recommend? Thanks...

I managed to blow the fuses in my Klein MM400 multimeter and when I replaced them I was still getting a cal and error0 message. I started looking around the board and found one resistor that was testing OL and has a visible burn mark on the top of it so I can't tell what the value is anymore. Its marked as R19 on the board and I included a picture below of what it looks like.

Hello,

This tablet has no power, no visual signs of corrosion or burned components.
I notice V_ALWAY_ON_IN on PD5501 and PD5506 is 12V.
But VDD_BATA_PACK on PD5501 is 2.05V when the charger is plugged in, after a little over 1 minute VDD_BATA_PACK goes up to 6.16V
FANG_PWR_F stays 0V.
+3P3VSB_REG is only 1.98V
+5VSB_REG is 0V

I cannot find shorted coils or coils with low resistance to ground except for the ones close to the PCH/CPU.

Had flickering touch bar display. Replaced. Now have an intermittent touch reponsiveness. It generally works but sometimes a press would not respond and need to touch again... sometimes more than 1-2x. Generally happens when trying to go faster on the touch bar and seem more common in certain regions on the bar.

Closer inspection reveal L5100 (touch sensor power rail coil) had overheated in the past. Perhaps it can't supply voltage or current properly. Don't have component available so thinking just replace with 0.1mm wire. Touchbar works now but touchbar just have some sluggishness...
