Hi as you can see from title, I have a samsung tv here that will show the smart tv logo and then no picture after that even hitting input or menu on remote and shows nothing but the backlight still appears to be on. The tv will turn itself off after a minute or so automatically. I'm somewhat confused if this is either a eeprom problem or a bad led strip problem. The power supply makes a pretty noticeable humming sound when it's turned on leading me to believe one of the leds are shorted but idk honestly. Any of you guys have any help for me? I have a good multi meter and can take pictures of whatever...04-13-2024, 10:05 PM

Hey, everybody.I'm asking for your help. Brought this TV in to replace the backlight. After replacing the backlight there are such stripes (see photo).
The glass is not broken, decoders are intact, everything was done very carefully and in antistatic gloves. The experience of disassembling such diagonals is great. I do not understand what is the reason for such stripes that appear a couple seconds after turning on.
Loops rewired, wiped them with alcohol, the connectors are clean. Who by experience can tell me why this happened? Perhaps at the reception did not notice when shining the...Today, 12:29 AM -
Today I got a 65" TV from Hass company. It was not showing any picture. I taped the 6 lines of the Tcon FFC cable on the faulty side of the shade and the picture came but the display on the side where I blocked the pins was not showing properly. I checked the volts on the VGH point and -3.5 volts was abnormal, there should be about 28 to 30 volts on this point! There were +30 volts on the VGH point on the Tcon. I put a jumper on the source PCB from the Tcon side and saw, the raster started appearing on the display. I also tried soldering the 6 blocked pins but the picture did not come properly....Yesterday, 04:54 PM

Hi, everyone. First post of an actual repair. I'm a technician but a complete newbie with laptops.
So I got this Dell Inspiron to play with.
No charger, so I connected to my bench PSU.
The laptop also didn't include: hard disk (I added one of my own for testing, see below) and wireless PCB (but I doubt this could have anything to do with this particular failure).
------What it did (and didn't do)------
1) I turned it on and it powered on. Powered down in 2 seconds by itself.
2) Removed RAM, changed slot. Same...04-04-2024, 12:39 PM -
I would like some help and advice which will be much appreciated, I am looking at a mac Macbook Pro A1990 board 820-01814-A. When I connect the USBC meter via external Power Supply I see Power cycling between 5v.040 A to .468A then it repeats.
After doing some diode tests I get a complete Short on L9530 which is the output inductor for PP1V8_ssd1.
I have given the screenshot here, I would like your recommendation and advice if anything I need to test get this issue sorted Or is it SSD short , Your help on this will be much appreciated...04-20-2024, 11:41 PM -
Hello, I have the following laptop:
HP Pavilion Aero 13-be0003ca

Motherboard information is below:
HP Part# M52826-601

It needs BIOS repaired.
I created a flash drive using HP firmware utility and then had it plugged into the computer. I did the standard WinLogo->B key->Power button press. A window appeared and immediately began flashing the bios using the flash drive.
But I don't think it finished all the way. So, now when I attempt...04-21-2024, 10:57 PM -
Recently had my bedroom Vizio D40u-D1 apparently die while it wasn't being used. Noticed the power LED flashing, figuring maybe a software upgrade, but attempting to turn it on proved that wasn't the case. When powered on, the power LED will flash a bunch of times after about 2 minutes then turn off again. Definitely is no picture even with a flashlight on the screen. Had the opportunity to open it up over the weekend. Doesn't apper to be anything out of the ordinary visibly inside, nor any odd smells of escaped magic smoke. Readings from the connector in the corner of the power supply board...04-02-2024, 08:55 AM

I got paid to take this. It had the typical DPS STBY IC bad. Replace it and life was grand....or so I thought. I've never seen this one before; this TV will just magically turns itself on for no particular reason on earth. I did a hard reset on it (twice) clearing all data & settings out.....will still do this. Even removed the batteries from the remote....in the unlikely even there was a stuck key... Still doing it. I did not set up any of the 'smart' functions, I just fed it a source from a HTPC. It doesn't matter what input is selected.....still does it. No rhyme or reason as to frequency....Yesterday, 05:00 PM

For those in 220V locales, anyone power their SMPS with DC, and how high of a voltage is okay?
What kind of PSU?
I suspect that 240V * sqrt(2) = 340V DC is probably fine because that would be about how much the the primary rectifier ends up with peak voltage. Just wondering, other than input capacitor voltages, can one go up above this 340V without damage? Will that input capacitor be the upper bound?
Wondering if exactly that, can I feed near 400VDC into bona fide specced at 220V SMPS without damage?
Currently have a 120/220V switchable SMPS I want to see if I...Yesterday, 08:03 PM

Hi people, i have an acer nitro 5 with motherboard model gh51m la-k861p , it came with the resistor pr103 blow up, i repaced that resistor, i check the coils plb2, pl301, pl501 and has no short to ground, i conect the charger and it doesnt power at all, i check pqb3 on pin 5 to 8 and its 19v, pin 1 to 4 its 0

So I'm having difficulty finding line drawings for this motherboard NM-C53. My charging port was broken. So I replaced it with a terrible solder job. Problem is pin 3 on the drawing I saw on here has it listed as adapter-id. Now I checked my other pins and I have continuity (resistance check from power to ground). Pin 3 shows nothing. Now I boot the computer and it says to use a power adapter with the proper wattage and won't charge. I have read that pin 3 is usually tied to a resistor that identifies the charging power thus disabled the ability to charge if it fails the check. I look at my board...Yesterday, 07:27 AM

Hi.
My Hp G6 laptop died while using it.

HI guys!
I've got a Samsung LH82QENELGC/EN with a problem and need some advice and I hope this is the forum to use?
I'm from Norway so I'd like to apology in advance if my description of the fault is kind of simple or the names on the components are way off. 😊
the TV is powering up, working as normally and picture is all good, except a 1.5-inch-wide vertical line of snow/static across the screen.
This TV is a Signage Display/Public Display version and it's been used at my work for 4-5 years showing commercials 24/7. The fault occurred when...Yesterday, 11:28 AM -
Hi all,
I'm becoming crazy trying to fix the Philips TV of my old man (model 43PUS6201/12 - the TV, not my dad). I've read again and again discussions about this and similar TV models, on badcaps (thanks so much !). I see no other option than asking for your help.
The symptom is simple : when I plug the power cord, the red "stand-by" LED does not light on anymore, and the TV powers-on neither with the remote control nor with the rear button. I guess at this point you immediately think at the 5V (or other voltage depending on the hardware) stand-by output......04-20-2024, 02:56 PM -
