Re: LG 42PG20 sound no picture
Could someone look at this picture?
I drew the voltages on the picture...
That 8 pin IC is a 200D6,I can not find specs on it.
The voltage on pin#1 of that IC(left bottom pin) is directly connected to the resistor left below it,one side of resistor has 187v solid,other side(IC side) it climbs from 107v to 143v and then back to 107v in about a 3 second interval..
On the pic you can (kinda)see how that IC connects directly to the Mosfet that has 187 on only one pin..
Is it safe to say the IC is not functioning???Attached Filesif you find these attachements useful please consider making a small donation to the site

Hello Guys,
Greetings!
Hope you all are doing well.
I am looking for suggestion on Yamaha 2064. The problem with this receiver is that it has no sound however when the test tones are activated it does outputs from all the speakers. It is working in two channel stereo mode but when you select other sound modes, it doesn't. The last time it had a problem, I had replaced the DAC
PCM1681DBQR - IC263 and it worked fine.
Other issue with it is one of the STK ICs is getting more heated then the other one but that can be looked at later.

I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.
I ordered a supposedly ‘new' Tcon board this time, and... -
Hello everyone,
Ive got a UE60KU6079 on the workbench that is giving me some headaches trying to troubleshoot.
The previous owner stated that there had been white dots on the screen which from the description sounded like some lenses fell of the backlight LEDs.
He had opened the TV from the back, trying to get to the backlight, supposedly gave up, reassebled everything and gave the TV to me.
I expected the worst like ripped COF cables or a cracked panel but could not find anything like that yet.
Anyway I still fully expect that there has been something seriously damaged... -
Hi all
I was just given a Samsung TV with the issue. I read various threads and videos and attempted the ribbon tape method to gain an image, but no luck.
Symptom:
No picture no sound.
When I plug in the power cord, Backlight LED turns on for a half second and then turns off. The red LED next to the power button located center bottom flashes 2 or 3 times. When the power button is pressed after, it does the same thing.
No sound at all.
What I tried:
1. I tried unplugging the left or right ribbon... -
so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!!
what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol! 
i had to blow some dust off the board and heatsinks with the datavac as i didnt clean it up before putting it in storage. after finishing...
