Panasonic TH50pz80u

[Tvbob]

Hello fellow enthusiasts
I had this set in my garage for years.. Had the bad y main 7 blinks flashing of the power light. I acquired a Y-main and both upper and lower buffer boards from a set with a bad power supply. The boards fixed the 7 blinks but I have horiz lines. I also reinstalled the original buffer boards with no change.. should I look for another Y main... or is this a bad panel. Thanks

If you have the mainboard too, swap it and see if it helps.

Try reinserting the ribbon cables. It took me a little over forever on a 55” Panasonic.

I have swapped Two sets of buffer boards lines stay the same...I think too many lines for ribbon cables.. lines are also in the on screen display menu

Re: Panasonic TH50pz80u

Is that a picture of the original power supply or the replacement? The reason I ask is that one of the three Vs caps (one on the left) looks a bit domed, It might just be the way the photo was taken.

Thanks R_J.... Your are so right.
2 of the 3 vs supply caps are domed.I don't know how I missed them.
The tv is sitting on my garage floor. That doesn't help
I will check VS supply and change the caps and post the result...Thanks
