Question about Toshiba 46H83 46" Rear Projection HDTV-Ready Television

Major screen problem with 46H83 - HELP!

I don't even know how to describe this... sometimes I get no picture at all and the menu options appear "curved" on the screen. Sometimes the screen goes insane with different colors flashing all over the place. Sometimes I lose vertical or horizontal hold. Sometimes it appears that only the red/blue/green lamps is working. Sometimes, albeit very rarely, it works JUST FINE. The solution is to turn it off and turn it back on, but the problem persists soon thereafter. Has anybody encountered something like this? I'm desperate for help. Thanks.

The convergence IC first need to be changed and this might cause all of your problems to go away. if it does not then theres a bad capacitor in the sweep power supply thats bad also. but as I said change out both STK convergence IC's first.

Hey can any one help me with my Toshiba 46H83 rear projection hdtv? My screen is off center by about 3/4 of an inch to the right. The picture is prefect except for this. I've asked this question two times...

OK, need to go to service menu of TV and adjust HPOS data, you can move entire picture left to right or right to left to adjust it on TV screen.
Be careful NOT to initialize service data memory otherwise all convergence will be a mess.
How to go into Service Mode is written in service manual of TV.

Picture is Dark on all stations

It sounds like a bulb. I would call toshiba and ask them what the replacement part is for that. I briefly googled for it but couldn't find the matching bulb for the 46H83

Horizonatal lines on Toshiba 46H83

If the repairman you had look at the set is used to working on projection sets, have him come back and Re-Solder Connector Px801 (Edge Connector) On The G-Hyper Module. (Pins 1 And 2 Of Px801 probably needs to be Re-Soldered) Otherwise, find a different repair person.
