Re: LG 50" Plasma 50PS30-UB powers on, no picture, no sound
Anyone? I'd like to know if this new issue is fixable or if it just sounds like a bad panel at this point.Leave a comment:

Re: LG 50" Plasma 50PS30-UB powers on, no picture, no sound
Bump, I replaced the t-con/control board and now I have picture!
However the picture is slightly solarized in areas, and the whole picture appears to be on the dark side. What could it be now? I saw something that said it could be bad z-sus, but I also saw it could be bad panel which I really hope nope considering what I've already put into it. Any one have input of what to do now?Leave a comment:

I've checked for it on the y-main board at the designated test points and it was good. Is there test points on the lower buffers as well?...Leave a comment:

Re: LG 50" Plasma 50PS30-UB powers on, no picture, no sound
Since I've had no response, I decided to buy a new (used) t-con/control board to see if that is the proble.
Would appreciate if someone would chime in, thanksLeave a comment:

Tried booting up tv with only upper y buffer attached and then with just the lower one attached to see if I got any picture, but still nothing on screen. Also do not appear to hear the slight humming i should hear from y main board. Anyone?Leave a comment:

Well since the ysus voltages checked out fine, gonna try replacing the lower buffers since they are cheap.
I'd Really appreciate it if someone could chime in with something else I can check out, thanksLeave a comment:

Update guys
The wrong mainboard I tried above let the tv have sound but still no picture. Then Bought a used board of the correct model and have no pictures or sound still.
Also should I hear a click from the y board when I turn on the tv? I only hear a click from the power supplyLeave a comment:

Actually just double checked. The EAX number matches but the EBR is different (1 digit off). Of course the one that matches mine is more expensive >

According to my order number the EAX number is the same. Is it possible there is more than one design for the same exact part number that is compatible with my tv?...Leave a comment:

Re: LG 50" Plasma 50PS30-UB powers on, no picture, no sound
So I bought a new (used) main board and installed it. Now I have sound but still no picture. I ordered by part number but the board I got has a couple inputs in different places. Would the fact of it being different cause it to only partially work like this?Leave a comment:

Without removing the board, none of those 3 appear to be showing OL. Would you suspect power supply? And was yours having the same symptoms?Leave a comment:
