I have a 46 inch Toshiba plasma tv. It is having a problem where the picture does not come up as soon as I turn on the TV. After about 20 minutes of warming up, the picture appears as normal but during the warm up period, the screen is distorted and on most channels, the screen is black. On some channels, you can see shapes but there would be a funky color set up and blacked out sections of the screen.

Power supply board has some components that have failed. You can get parts from here: TV Parts Universal TV Stands DLP Chips ShopJimmy

Your LCD panel has failed, it will be cheaper to get a new set. If I have helped you please sign my guest book

Sounds like you either have a faulty LCD panel tab, failed LCD driver board, LCD/t-con panel bad connection, or a bad t-con. You will need to get a diagnoses to be sure.

I will be the barer of bad news. your Panel is failing. Plasma TVs are only made to last 5-7 years. 10-12 is more realistic from what I have seen. The TH46pz85u is a great model of TV but when that starts happening it means the panel is beginning to fail. Replacing the panel is cost prohibitive and they don't even make them anymore.

You will be wise to spend your money on a new TV. newer TV's are much more power efficient as well. your 46" TV draws a lot of electricity. Your TV draws almost 650Watts of power. A comparably sized TV today(55" or larger) Draws around 200 watts. Significantly less.

Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish board that call T-CON board to do a replacement.This T-CON board sit in the middle at the bottom of the tv LCD screen panel.This T-CON board control all the picture pixels going throught to the tv LCD screen panel.

i have the same problem on my tv and i call to bestbuy since the tv is only 2months so still on the manufactures warranty the problem is SC Board shorted, and they replaced the sc board.

when i turn my 32 inch VIVIO plasma tv on it turns pff by itself. i want to know why this is happening

my 46'' inch tv polaroid lcd has been working fine for 3 years. today my wife and I noticed the tv is shutting off the screen will go black and the power light does switch to red. you can here something inside the t.v clicking but you can turn it on and it will start back fine for 20 minutes then shut off again? Does anybody know whats going out on the tv? let me know

The only logical solution for the problems people are having for the toshiba regza's tv's is to get into a class action law suite..., they contiue to sell tv's with defective parts and refuse to help the customer that spent large cash to find out they last if your lucky 2.5 years, they are junk and anyone with one will soon find out./.......

I had the same problem. It turned out that one of the cooling fans get dusty and does not work. I opened the back of the Toshiba plasma TV and cleaned the failed fan, and it worked like a champ.
