Hey everybody,
I picked up a Panasonic TH-50PX500U plasma tv for free the other day. I was told it had lines going across the screen, so I did research prior to picking it up and thought it would be an easy fix. Turns out that it has more serious problems. As you can see in the photos I've provided, the screen shows a sort of multi-colored scramble in vertical lines. I don't really know what to call this, so search hasn't been very productive.
It is a strange problem to me because it happens on all inputs, but some things show up fine. I've hooked it up to my cable box via coaxial and HDMI, and both show a faint picture through the scramble. I wasn't able to get a photo of this, but the TV Guide feature included in the tv shows up the same way. As you can see, each input has its own variation of the multi-color scramble, and the on-screen input labels are messed up as well. Except for the PC input label, which is normal, and the HDMI input. HDMI is blank with a messed up label when the cord is not connected; it is scrambled like the other inputs when plugged in. And when it's displaying two inputs side-by-side, everything surrounding the input images is normal.
The Main Menu box shows up on all the inputs, but is itself scrambled. However, when accessing both the Picture and Audio menus, they show up normal. I've also attached a picture of the Self Check, which is not scrambled and shows the results as all OK. And the Service Mode menu shows up normal. I can provide all the values if necessary. I've also tried the Factory Reset code given in the sticky'd thread, but doing that just goes to the Self Check.
I appreciate any help with this issue. I've opened up the back and nothing stands out to me as being obviously wrong. I have a little experience in fixing electronics and am proficient with a multimeter, and consider myself quite handy in general. I'd love if I could fix this myself; I'll put time into this project but don't really want to put a ton of money into a 10 year old tv. Hopefully this isn't a lost cause. Thanks a lot.
Cheers,
Jake
