Re: Sharp LC-60E77UN Backlight Problem
Did you ever find what the problem was? I have a set doing the same thing and don't want to waste money on inverter boards if its burnt out ccfl lamps.

Daytek DT-4640
I got a daytek dt-4640 LCD TV that would not power on, opened it up and found a blowen cap on the secondary side of the power supply I recapped the secondary side and now when I turn it on the power led goes green for a few seconds the turns red blinks once then a pause then three times another pause then twice and then blinks very fast and repeats, any one know what that fault code might mean? I have been unable to find any info on this TV. It uses a Samsung panel. Any help would be great just have not spent a lot of time on it yet.
Thanks -

What to do Fix or Part out?
So I picked up 11 TV's mix match of Plasma and LCD from Scrap collector and two boxes of boards and now don't know what is better to do? Fix them or Part them out? I have fixed three of them already and have figured out the problem with most of them but don't have any family members or friends that need anymore tvs and would maybe like to make a few bucks off of them but not sure what is better?
Buy replacement boards to fix and then sell the Tv's or to part them out to fix other tv's that people are trying to keep working either way they are out of the garbage pile.

Re: Plasma LG 60PG30 - Horizontal Line (Bottom)
Sorry tired to find it on your board even looked online for higher res photos and can't find anything all I see is ext on a connector on the top right conner but don't think that is it, Tom might be better to answer this question as he told me about this trick not that long ago but has come in handy a few time already.Leave a comment:

Re: Plasma LG 60PG30 - Horizontal Line (Bottom)
What happens if you remove the bottom buffer board? Also have you tried enabling the ext auto gen feature? There are two Gold dots on the logic board which if you jumper it will form a test pattern.Leave a comment:

Re: LG PG5010-UA Plasma Blinking LED and Clickling
I was reading vs and va from the sus connectors on the power supply and the gnd from the connector but also tried gnd from chassis ground the resistors where from the back of the connector from 5v to rl on and vs on from the connector going to the main boardLeave a comment:

Re: LG PG5010-UA Plasma Blinking LED and Clickling
So i put a 470 ohm resistor in the back side of the connector where it says 5v and rl_on and one for 5v and vs_on and removed the connector to the main board when i plug it back in get a click and a green led lit on the control board and then it turns off tried a jumper from auto ext gen and vs_da and nothing also no voltage on va or vsLeave a comment:

Re: LG PG5010-UA Plasma Blinking LED and Clickling
Tom,
I went to go try and do what you susgested but could not find anything on the logic/control board that said EXT AUTO GEN to short out or jumper, Also went to go test the power supply voltages and could not get anything off of VA or VS I still suspect it could be a power supply but i did unplug just to connector to the main board and when i plug the power in it only clicks once, but with the main board connected the relay keeps clicking on and off and a led on the main board LD703 is amber and the other is green...Leave a comment:
