Sound no picture 56h80 toshiba


This set will blank the picture for several different reasons:

No filament voltage to the three tubes it uses.

No high voltage to the three tubes it uses.

No vertical or horizontal sweep (prevents all three tubes from having the screens burnt with a line.

Some of these can be tested but most require a schematic etc.

Set has several fuses and some do not look like fuses--called pico fuses.

Remote sensor location


Remote receiver is located on tiny PC board at the top and just in front of the middle of the three picture tubes---board is about 3/4 inch wide and maybe 2 inches long----pretty standard IR unit.

Look from back with back cover removed and it is in front of the middle lens there.

Toshiba 61 inch rear projection scrambled picture for 10 minutes after power on, then clears up.


If you are seeing lines and or noise for the first several minutes and it goes away--I think I know what the problem is.

Has the period of time before it clears up been getting longer and longer?

Reply to me with the exact model number and I will tell you what is wrong and what has to be done to fix it.

A lot of these sets have problems with what is called a HYPER board----it controls all signal inside the set--confirm Toshiba and exact model number---

No picture is it the bulb and is this hard to change?


You DO NOT have just a bulb in your set. You have the older style Projection TV with three picture tubes. It's a good possibility that you have a convergence issue that has blanked the raster and therefore you will not see a picture until the error is corrected. Have it looked at by a qualified technician.

Where is the hard reset located


This is not a problem that a "reset" will resolve. There is a problem with the convergence circuit. It may be as simple as poor solder connections on the convergence ICs. If you can solder, you can fix this yourself. Please let me know if you wish to attempt the repair and I'll supply additional details and instructions.

Picture is blurry, but perfect sound


Sounds like a ground leg on the distribution block has loosened up and is not properly grounding the screen drive. worst-case scenario is that ione of the tubes (3 picture tubes) has started to short out and is causing the blur.
