Question about Toshiba 50HP81 50 in. Plasma Television

Open Question

Screen shuts off, color dissolves to black

I recently purchased a used Toshiba 50HP81 and it worked when I got it home. I was using it for about 45 minutes the first day and everything was fine and the picture quality was outstanding. The second day when i powered it on, red pixels came up in the bottom left of the screen and eventually the full picture came on after about 5 minutes of messing with the hd cables (which i realize had nothing to do with it). The picture since then has not stayed on for more than 15 minutes or so at a time before dissolving the pictures to black and having no visuals for about 3-5 minutes then repeating. The power/standby light does not blink indicating any errors. I'm thinking maybe there is something circuitry related and not screen related, but im new to plasmas and don't know too much. I would be able to replace resistors/amps inside if that was the case, but I'm not sure how to figure that out. Any help would be great, thanks.

Your Cable box might need to be reprogrammed. Call the cable company and they will drive you thru the steps to program it, this way you will get the channels. This process might take you 30-45 minutes.

Try changing the picture setting on the television rather than from the picture box.

As stated by the previous expert the fault is clearly a lowering of value of a capacitor or in some cases an IC or semiconductor. You can use a heater to SIMULATE the board in different section when the set to put ON and confirm the right place to where you can checck to replace suspected capacitors.-- in TCON or worse the LCD itself.

I have a 2005, 42" toshiba LCD model 42DPC85 that when we turn it on everything is good except the whole screen is black but imediatly the colors dot by dot start making the black disappear, it only took...

You need a new DLP chip. The chip has little mirrors that are black on one side and white on the other side. When the chip wears out , your screen will turn white one dot at a time or black one dot at a time or they may just all stick shut at once. Since your screen is black, all your mirrors are closed. You can buy the chip from and they have a video of how to replace the chip so you can do it yourself. It takes about 1 1/2 hours. The chip is about $160. To have this service done for you is about $200. Do it yourself and save the money. Your tv will be just like new again. Just make sure the chip is in perfectly level or when you turn your tv back on, your picture will be slanted. you won't notice it on the picture itself but words on the screen or scrolling messages and the menu will be slanted.

Toshiba Regza 42 in - have no blue or yellow colors - all green and red - TV was purchased in Aug 2008 - this is a recent problem - changing settings on the color spectrum didn't work

It sounds like you have a driver board problem. I suggest getting in touch with Toshiba and see if they will have it diagnosed/repaired under warranty. If not, they can give you the name and number of an authorized repair center who will know best how to diagnose and repair the problem with those units.

I have a toshiba cx35d60 and the picture just randomly turned to a lighter color and has white lines all the way down the screen also when i shut the tv off i see a red blue and green light in the middle...

This type of fault is usually caused in the screen bias circuits, or in the blanking circuits. It is also possible to have this symptom from a short or a resistive leakage inside the electron gun of the picture tube.

A TV is a fairly complex device using many hundreds of various electronic components. As it ages from use and age its reliability will decrease. Especially with older sets, it is very possible that when you service the set there could be other faults shortly after.

Take the television back to where you bought it and maybe they might repair it or swap it. It sounds like a defect in the TV.

BUT! Are you sure that its not just the aerial signal??

"Popped"? That sounds like a serious issue that is going to require a warranty repair or a professional TV repair person to address.
