Sounds like your dmd module. its the part of your optical block that processes the images that make up what is projected on your screen.. without a model # i can't tell you the part #

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---

Picture loss


It sounds as though you have what is referred to as a climental problem. In laymen terms, a transistor, chip or regulator is heating up and breaking down. The way a technician normally isolates this type of problem is by using a cooling agent ( freeze spray ). When the set heats up and the picture goes away, the technician sprays some of the cooling agent on a part of the board ( select a small area, about 6 inches square ) at a time and see if the picture comes back on. When you do finally get to the bad area, the picture should come back on for a short period of time until the bad part heats up again. After a period of time and by using the freeze spray, a person can isolate the exact bad part. Replace that bad part, and any filter capacitors hooked to that bad part and the set should work properly. As always, use caution and unplug the set before opening the set and when using the freeze spray, be sure not to touch any connections in the tv as they could produce shocks.
I hope this has helped and good luck on your problem.

Flickering and freezing of picture for a split second


The most likely problem for image problems and flickering is the lamp (23311083A). I found it at PartStore.com for about $180. Hope this helps.

Toshiba 51H83 51 in. Rear Projection pisture issue


I have a wild guess. I have the same tv and channel 72 is the proper channel to watch tv on. I don't know why, but maybe try channel 72 instead of the usual channel 3. Good luck, maybe a quick fix, maybe not!
