Re: thosiba 32DT2U1 dead
That means something on the main board is loading down that ACD pin.
Remove that 1K resistor that is connected to the ACD pin on the main board, then you have to measure that ACD pin on the main board to see how low the resistance it has.
You are sure that 1K resistor you are using is good, if it is good then if you remove that end of the resistor that goes to the ACD pin of the main board, it should then show 5VDC at both ends against GND.
Can we see how you hook up this 1K resistor to the main board ACD pin?Last edited by budm; 10-25-2015, 11:39 AM.Never stop learning

I was wrong , at the 1 k reistor to the main board 4.598 vdc when the green pilot light is on.Attached FilesComment

Re: thosiba 32DT2U1 dead
So with the resistor in place with solid connection you are able to get the TV to function?Never stop learning

Is the BGA on the PCB or control board?Comment

the bga chip that some times causes issues is on the main boardComment

To all the members here...
Let me tell you a little bit about what happened to my laptop (MSI GF63 THIN 11UCX model: MS-16R6) that “maybe” you know how to solve this problem.
So before this problem happened, my laptop was running smoothly. When I wanted to restart my laptop, it looked fine at first. But after I waited for this restart process to take a long time, until finally I panicked (because the restart process did not finish plus the laptop screen only showed a black screen), I immediately pressed and held the power button to force the laptop to turn off. But... -
Hello, I have an Acer Aspire 4520 from a couple of decades ago and I want to repair it solely for nostalgia.
It happens that when I turn it on after having been disconnected for a long time, it turns on without problems, it tells me that the BIOS has been reset and that it will load the factory settings, if I tell it to continue, the computer turns on and everything works fine.
The moment I turn it off and want to turn it back on a second time, or restart it and try to start it again, it no longer gives an image, and it no longer responds.
If I remove the... -
Hi everyone,
I am dealing with the problem of turning on and off my Dell e7470 notebook.
The battery charge light is solid white, I press the button, the power indicator and the light on the button are solid for 1-2 seconds and immediately turn off.
The system does not turn on, there is no post.
I removed the RAMs and changed them, changed the battery, RTC battery, AC adapter, removed them and waited, tried again, it does not turn on.
The problem continues in the same way.
I tried to turn on the Fn key, nothing came to the screen.... -
i got this laptop with no power issue....i flashed the bios and laptop can turn on and use normally....but when i shut it down and rest for few minute (2-3 minutes), it wont turn on....i have to flash bios again...any idea what is the problem?...when i shutdown and suddenly press power button to turn on, it will turn on normally....problem happen when i rest the laptop 2-3 minutes after shutdown, it will not turn on....i need to flash bios again

Hello:
I have both these laptops that appeared to have the same fault so I thought I would have a go at replacing the PCH as something to learn, they both are using the same PCH.
I started on the ACER:
Up on connecting power no signs of life but current is consumed from the bench power supply and the PCH is hot.
All the caps on the top of the PCH are showing 0 ohms and the 3.3v rail is shorted.
I followed the videos from Sorin, Electronics Repair School on Youtube heating from the bottom to install. I practised on around 10 scrap...
