    This is a common problem with Toshiba projection sets. The board inside the set encased in metal shielding called the Hyper Board. There are many small surface-mount electrolytic capacitors on this board and some of them need to be replaced. again replace the stk392-110 or stk392-150 with ever one you have Replacing surface-mount capacitors on a board that asmall is no easy task and should be done by an experienced tech.i think that should solve the problem

Symptoms shows your TV has few capacitors weak (lower in performance) in power supply board and horizontal area. If you know how to unsold and sold components, check leaky capacitors in above stated area.

You do not have individual lamps in that model. You have 3 individual picture tubes of which I don't believe they are bad. They have fluid in a reservoir that becomes cloudy after time and needs to be replaced, however this is something you cannot do yourself. I recommend you call a qualified technician to take care of it for you.

Somewhere along the line you may have missed a cable connection. Recheck to be sure that all of the wires are reconnected. Also, check the +5V line. In the area of the convergence Ics there should be a number of pico fuses. One of those may have opened up.
Keep us posted.

Bad picture until tv warms up


this is a very common occurance in these sets. toshiba has issued a servece bullteen with this set. Sorry to tell you this but this is a problem with some very small capacitors on what is known as the hypermodule. in my shop we fix 2 to 5 of these a month. you really have to know how to solder. Idealy replace the hypermodule is the best way. but......that board is hard to find. so we replace these 11 very very small componets with twezzers and a big magnifier. we charge about 250 to 350 for this repair.
