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 FilesProud owner of dozens of broken TV's and many,many,many boards.

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... -
Hello all ~
I’m working on this Samsung 60” LED and purchased a new main board a couple of days ago that did not fix the 5 blink issue. The original main board’s HDMI ports (all 4 of them) failed to work and no amount of reflow remedied that.
This 5 red light blink code on the front panel LED is followed (about 15-20 seconds afterward) by an automatic reboot, and results in 5 more red light blinks. Then the entire cycle repeats itself indefinitely.
No picture. No sound.
I tested all the voltages coming out of the power supply...
