Toshiba Plasma clicking noise

Hi John,
The next possible thing is the main board. I have done it once. Good Luck.

How much lld are you? How many Plasma sets did you repaired so far? Do you think repairing a plasma TV will be very like eating a ripe banana?
Contact any well experienced service technician; man.
"YOUR WORDS above REFLECTS YOUR IGNORANCE IN SERVICING SUCH ADVANCED TECHNOLOGY SETS.
What else to say? http://electronicshelponline.blogspot.com/

soundslike you need a new TV or get this one repaired .

I have a 60 in. Vizio, but I'm pretty sure this will help you out: With the remote that came with your TV (not TiVo, ScientificAtlanta or some other device programmed to control it), press the menu button, then click on audio. You should then see a choice that says "lip synch" or something like it. Click on that and a bar graphic should appear on the screen that looks something like this:
_ __________________ +. This allows you two synchronize and set the audio with the picture - either slow it down or speed it up by a few seconds either way by using the TV remote. I've never had to use it with my Samsung HT, but I know it's there and I know it's function. My TV is also a smart tv, so this should work for you. Good luck. . .

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?

Sounds like you need a new color wheel

Without more detail it's impossible to say for sure. It sounds like the bulb may have gone bad and that needs to be replaced.

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.
