by reassorHi.
I got dead one.
3VALW is just pulsing then goes down. i removed the jumper PJ402 and it suddenly stays up but PG pin on that IC is around 0.5v and droping.
There is no obvious shorts. Wierd thing is that on the other side of the PJ402 i have 1.4V from somwhere ...
Injecting 3.3v there draws 300mA and nothing is heating up.
the ic is SY8386BRHC_QFN16 (kinda uncommon here - so i do not have a spare to test it)
any ideas to check before i order a few of these?Today, 01:47 PM -

Very new to this. So pretty basic / silly question. Can this be the cause of a totally dead mobo? And, is it repairable if I bridge tracks etc?

by sretchko[FONT=Arial]Hey fellow solder fume lovers, I have a Vintage Sony Receiver STR-4800 SD that has me stumped. [/FONT]
[FONT=Arial]The Balance Pot has to be set at about 30 degrees (11 o'clock) to the left for the output to be balanced (see photo). I'm using an oscope, sig gen 1kHz sine, 8 ohm dummy load).[/FONT]
[FONT=Arial]When output is balanced (11 o'clock left) both channels clip at about 19 vac / 45 watts RMS, Amp is rated at 35 watts so I know the amp modules are good. Square wave also looks good when turning bass & treble pots and is in phase. [/FONT]

by stingerWhen I turn tv on, the backlights come on but there is no sound or picture. I have read that these tv's have problems with the panels going bad but the "no sound" has me questioning if the main board is bad. Is there a way to troubleshoot the main board to determine if that is the problem?Today, 03:06 PM

by crosswindsHello,
So, pulled a motherboard out from storage, was working when put away, wont post when I took it out of storage today.
Since it was working, and it looks to be essentially time that killed it I figured its a good idea to replace the caps before digging further.
Looks to be only good quality caps on this board, so might not be the issue. But it is closing in on 20 years now so, wont hurt i guess
Its a ASUS P5VDZ-MX board.
I would really appreciate some assistance on what the best replacement caps would be for these:

by Super360Hi 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...4 Photos04-13-2024, 10:05 PM

by trepachkaSee attached image. It says "X322" on it. This is a follow-up to my previous posted topic. The issue is upon lid closing, the screen turns off. When lid is opened, the screen remains dark.
This component is positioned right on the edge of the motherboard and has like a cradle made inside the case. I am assuming this component is used as a lid close sensor.
Please, help me identify it. Thank you....Yesterday, 03:26 PM -

by Carl0s-Hi,
Sooo - our IT got a pile of old iPads that the sales guys have been mistreating. These are free for grabs if you want to try to get one working. Thought I'd give it a try - if I get at least some life to I can give to my kid to entertain during a car rides.
But the iPad it self - its a 5th gen cellular model. When I initially plug it in it was completely dead. It was not recognized by my Mac nor it started to charge. Disassembled it opened up the battery connector and checked the battery voltage. My multimeter showed 0,7v. Had a spare micro-usb charging board lying...04-15-2024, 12:51 PM
