Toshiba Plasma clicking noise

SOUNDS LIKE A FAULTY RELAY HAD THIS FAULT PREVIOUSLY ON SAMSUNG -SONY-TOSHIBA

A case of which came first the chicken or the egg, Power supply board may be the issue or the sustain board--have you looked for the usual bad caps on the power board?

That model is an LCD that uses a backlight. Probably with CCFL tubes. They are known to have bad inverter supplies. Its an old TV though. Keep that in mind.

This tv is not repairable only can be replaced the Plasma screen itself.Not woth it,replacing the plasma screen,will cost the same as a new tv.This problems,u discribing is the Plasma screen itself sure comming to used and ages.Not any electronic boards componnent.Because the floorscents Plasma gas u seeing on the screen itself forming and lighting up the Plasma screen itself.

Hi did you ever solve this problem? i have the exact same issue, i think its the main-y pcb but want to be sure. green pixels, slow refresh rate on screen, after 5mins the picture is normal till next time i turn it on.

Check the fuses on the ysus & zsus boards. Are any fuses on boards open . Disconect power cabels to ysus board first {board on left} . put tv on . if the light is green the ysus board must be replaced.

most times then not it's the capacitors on your power board that blew there for not supplying the tv with enough power if you open it up and check the capacitors it should be leaking some kind of liquid or the tops have bubbled up. its an easy fix cost>>2 dollars each

I too have this problem with no help from hh Gregg, where I bought the tv, and no help from Toshiba. I resorted to calling the BBB and complaining about the defective workmanship. I took the tv, which is less than 2 years old, apart and found the y-sus board, behind the y-sus board is a foam rubber spacer to seperate the circut board from the backside of the screen. I think this pad is designed to prevent heat buildup in the y-sus board. The pad itself is held on by glue and that glue melted causing the y-sus board to short out. I noticed this after finding a tacky substance behind the board. The heat from the plasma screen melted this and also the pad itself. Toshiba claims no resposibility because the tv was out of warranty. Thanks Toshiba.
