Tom66,
thank you for the help with my last tv. it was indeed the tab bonds.
i used some weather strip foam and duct tape to support that joint. lol.
seems like its working fine now.

Re: Toshiba Plasma 50HP66

buzzing and ticking from the upper left (Y ?) board.
likely the culprit i guess.
will there be more damage?

Re: Toshiba Plasma 50HP66

Y sus and buffers bad. Possibly Z sus too.
Not usually work fixing these unless the TV was free or very cheap.

Re: Toshiba Plasma 50HP66

i might be willing to try some board repair if someone wanted to walk me thru it.
i have soldering tools meter etc. no real education tho.
