Open Question

I have a Toshiba projection tv model TP55E80 The screen went dark, but the out line you can see still has the picture. Does the tube have to be changed and if so do you know how to change the bulb?

SOURCE: toshiba projection tv problem

Hi, you have a failed convergence circuit, you didn`t list model & chassis number so I can`t tell you which IC`s your set uses. this is not an easy job for a layperson that has never done this before, (requires removal of main board and un-soldering two large IC`s and replacing them) If you want more info ask away but be sure to give model/chassis so I know which set were dealing with, good luck, BMW Rider

Depending how long you have owned it and if a Lamp was ever replaced, it probably needs to be replaced. You can check with SONY at
1800-222-SONY and see if they could sell and send you one.
Hope this helps,

I have sound but no picture. Turns on/off with no problem. Checked settings including playing DVD and other video settings- picture just went out


The model indicated has 3 picture tubes (right model?) and will blank or turn the tubes off for several reasons--almost all are protection.

In this kind of set if vertical loss of sweep (in old sets you would see just a white line left to right) it will not permit the tubes to be on as it would burn a line instantly in all three tubes screens.

If this model not likely to be a do it yourself repair.

Toshiba 52HMX95 DLP has weird gray think line


DLP TVs work projecting light throught a tube covered with mirrors, called the light tunnel.

The gray shadow it is something in the middle of the light tunnel, probably a mirror that has gone out of place when you moved the TV.

Toshiba TP 50H50 Blank Screen


IT sounds like you lost your high voltage going to the picture tubes. This could be due either to part of the main power supply going out due to a defective capicator or semiconductor, or something more serious in the High voltage distribution network. With the age of the set, I would be most inclined to replace it with a new HDTV, and Toshiba still are pretty reliable sets. If you can afford it, a Sony KDS-55A20 puts out a beautiful picture for around $2300.
