Panny th-50px75y
Just picked up this unit and I can only select between TV and HDMI all others are inactive and I have something plugged into composite and component. Over the airwaves is plugged into antenna and has pic (poor, but displays something) I don't have anything HDMI where the TV is right now.
Is there something to change from the previous owner? reset all?
or am I missing something?
Thanks -

The kit comes with quite a lot. If I did it right, both sides go OL on the meterLeave a comment:

Boy I like talking to myself
ShopJimmy won't take the kit back, the package hasn't even been opened I feel that they should due to this. I could understand if it was opened.
So be sure when you order things from them. I offered them the old board for stock for free, but they wouldn't take it.
Anybody need a repair kit for cheap?Leave a comment:

Re: Lg 50pg20
Well after further review, my brother and I found 4 transistors(Trans) have been replaced on the bottom right heat sink(HS) which appear to be bad and the top trans on the left HS(is bad), bottom Trans on the next HS, & top and bottom Trans on middle HS have been replaced.
I ordered the ShopJimmy repair kit before we found the add'l 4 bad Trans.
It appears that this thing was repaired at least once before from the signs of the heat transfer paste, the repair kit will not cover all bad components.
What do the 4 replaced Trans control? ...Leave a comment:

Lg 50pg20
I got this LG 50PG20 from someone who said, it did work then just shut off. Claimed to have taken it in and was told it had a bad board, don't know which one. I cannot verify if this unit has pic or sound. There is power, frt led lights red>3 blue flashes>solid red (standby I guess), responds to remote. There is no click of any relays when powered and nothing gets hot. Not sure if I am doing it right, but don't get much of any readings from VS or VA anywhere, no fuses are blown. Pulled upper and lower buffers and nothing changed on the screen. need advise on proper testing on/off &...Last edited by Same; 03-05-2015, 10:26 PM. -
Re: LG 50PA5500-UA no pic
I contacted a local authorized LG repair shop. He took all my details and contacted LG. Appearently there is a service bulletin on this and the screen has a 2-yr warrantee. He said it would be $50.US to look at it and between 125-150.US for labor. The $50.00 would go towards the repair to swap out the screen incl. boards! -control and main boards I think he said.
I have the set registered in my name, I just don't know the exact date of purchase nore do I have the receipt. Also, the electronics store it was bought from is now closed.
Will I have...Leave a comment:

Re: LG 50PA5500-UA no pic
Well its all a moot point. I lifted the top of the panel from the frame to check on the upper ribbon and what may be causing the pressure point on these sets and to confirm if this set is one of them. I found it Damn it!
The upper ribbon has been compromised and has been rubbed through in a couple of lines. I have added a pic of the offending plastic tab (highlighted with whiteout) that is causing the damage and yes, if anyone has one of these sets they should try to remove the plastic and or part of the metal frame. I can see the same thing...

Re: LG 50PA5500-UA no pic
O.K. that's encouraging because there are a lot of posts with this set and the dreadded "worn-through upper panel ribbon" causing the most upper ic to short on the upper buffer and perhaps damage the y-board too.
I'll work with my Bro on the diode testing and other to make sure the y-board is good.
Those upper y buffers are hard to find for a reasonable $$$
Thanks againLeave a comment:

Re: LG 50PA5500-UA no pic
Thanks Drussel, I have better pics, I just wasn't sure on how to apply them at once, if anyone needs them I think I can do it now.
If I were to replace the y board and upper buffer I should be O.K. Assuming the panel itself isn't damaged.
If I understand correctly removing the upper buffer board test. If a lower half of the panel lights, then blown panel, which then means scrap the set.

Re: LG 50PA5500-UA no pic
Thanks for the reply, I couldn't figure out to get mutliple pics loaded. Va-55V Vs-205V. I found the jumpers on the psu board, but not the other on the y board or no exactly sure which one is the x board. Do I need to plug the y buffers back in to check for voltage on the psu?

LG 50PA5500-UA no pic
Hello guys, I have a LG 50PA5500-UA-AUSLLHR Plasma that I acquired that has no picture. I have some skills and tools, but not fluid with all terms and procedures. My brother is better, who I will have assist me from time to time.
The tv was purchased new 2.5 years ago, the previous owner stated “This happened out of no where when I turned the tv on one night and the picture just didn't appear. It didn't happen while I was watching. No noises or anything occur and I can still change the volume and change channels no problem.” Addl: nothing has ever hit the screen and the... -
