LG PDP42X30201 Picture Problem.
Just wondering if any one has any idea what could cause this. I replaced the y-main and buffer a while back, now it is doing this. it worked just fine for two months. then I started to see red sparkles then went to this....Last edited by wadenvk; 04-18-2014, 11:16 AM.

Re: 52"RCA Problem.
They are hooked up in series so two strips will power up at once, With the two strips are powered up there is no flash and I can read power on all 20 leds when I check down the line of leds when I get to the last two there is not enough power to light the last two up.
The new leds should be here today will put them in and see what happens. I will figure it out one way or another. Thank again for pointing me in the right direction.

Re: 52"RCA Problem.
Thanks waiting on the new led strips. the one strip that i have narrowed it down to when just that one is plugged in there is no flash but constant power there 81.6vdc and i can test each led they all work in series but when i get to 19 and 20 led there is not enough power left to light them up. weird.

Re: 52"RCA Problem.
Should that voltage jump around when powering up? With my test leads in place and powering it up voltage jumps to 160vdc then drops to 81.6.

Re: 52"RCA Problem.
Sorry was on wrong setting the dc voltage is 81.6 at the pin on con5 and 6 + and it is 81.6 at each led strip.

Re: 52"RCA Problem.
Alright I have tested this down to one strip that has different voltages. I was able to order all new strips but wondering if there is a way to find out what the voltage should be coming in to the strips from the board. right now I have 178v at the plug and at the start of the strip and gets lower as I light each led. The 178v take's care of two strips.

Re: 52"RCA Problem.
Alright I have tested the two strips that are not lighting up and found nothing wrong with them, I switched them out with known good strips and they do flash so I may have to head back to the supply.

Re: 52"RCA Problem.
he wires go directly to the led's I can get each side to flash plugging or unplugging CON 5 and 6. I have two strip's of led's that do not flash but I cant find anything wrong with them. I marked the led's that are not flashing.

Re: 52"RCA Problem.
I have been looking for shorts. Have not found any yet. You can think out loud I think we are narrowing it down some.

Re: 52"RCA Problem.
CON 5 has a black mark on it's not damaged. I tried Unplugging them one at a time with CON 6 there was no flash but lost 12v, with CON 5 there was a flash and lost 12v. I will start looking for a short now.

Re: 52"RCA Problem.
Now that I have 390 on the cap. I tested the plug.
12v= 11.92
12v=11.93
+5v=4.98
+5v=4.98
5vsb=4.98
on/off=4.64
+5v=4.97
