Lg 32LG3000 no picture
Hi!
I got this tv from a guy who said that before the tv showed vertical lines but now there is nothing on the screen.
When the tv turns on led flashes 2 times,backlight flashes and turns off.
I checked the voltages on psu and they seem ok, caps look ok too.
I tested the fuse on t-con and thats ok too. The inverter board gets 24v so I think that its ok too,but not sure,what do you think?
How to check the main board? What would be my next steps in troubleshooting this tv?
Thanx! -

Re: LG 50PS3000 clicks
Hi!
I got my board and the tv works but there are vertical lines acros the screen.
I tried cleaning the panel ribbon cables which go to y-sustain board and reseating them but it didnt help.
Is it a bad panel or is there a chance to repair the tv?...Leave a comment:

Re: LG 50PS3000 clicks
When i connect the power cable the board clicks two times fast, click-clack
Like it powers on and off right away.
There is no voltage at 17V pin.Leave a comment:

Hey
I did what you told me but nothing,no glow and no voltages.
What do you think, could it be just the ps board because i'm thinking about purchasing a new one.Leave a comment:

LG 50PS3000 clicks
hi!
I'm having problems with my LG plazma 50PS300.
I'm suspecting the power supply board EAY60716801.
When I power it on it makes 2 clicks and goes to stand by.
When I turn it on (button or remote) the LED blinks 6 times blue and then turns red.
The coil marked on the picture starts to buzz.
I mesured the voltages and they are all 0 except stby5v which is 5V.
Tried with all board connected to PS and all boards disconnected, its the same.
I also tested all fuses and they are ok.Tested all diodes and i think they are ok (not open or shorted).... -
