Question about Toshiba TP50G60 50" Rear Projection Television

TP50G60 bad scrambled picture - shuts off after 1 minute

See subject! Toshiba TV shuts off after 1 minute of turning on with the red light flashing. There is some semblence of a picture if I mess with the rbg setting underneath the speaker cover, but just outlines. It will stay powered for ~ 1 minute, then shut down. Any help? Should I replace the convergence IC?

Easy to fix. I have fixed this porblem before i do 3 to 4 tv a week and this problem happens all the time. There is a loader chip on the main circuit, Just replace this and you have fixed it.

This does not sound to me like a convergence roblem. It could be a shorted picture tube. That would put the set in a shutdown condition. Normally in Toshibas , the picture remains on with a convergence problem. Here is something you can try, but you must be very careful. Remove one crt board at a time from all three tubes. if the set stays on after one of the crt board are removed , then that is the shorted picture tube.I cannot caution you on how care full you have to be trying this procedure.

While i don't recall that particular pro lemme alot of Toshiba sets had an issue with the ballast boars. Basically over time the solder connection s get hot and cool so much that the joints Crack and breal. The ballast board may need to be resoldered. If you choose to try this yourself...be advised there are very high voltages inside a tv that can seriously hurt or kill you.

Toshiba theaterwide tv turns on and off on it's own and picture is messed up


I presume you unplugged set for a while and plugged it back to see if problem clears (allows set to reset).

If whatever picture you see looks 3d or colors skewed that is convergence problem.

2 things will cause this Lamp is defective, or Fan to lamp quits running this will shut TV OFF, if the fan quits running while Lamp is on it is design to shut Lamp Off to prevent Damage to Lamp IF Fans are ok It will be the Ballast board It is what turns Lamp on.Look on E-Bay for Ballast board if it turns out thats what you need or call Encompasss Electronics 1-800-638-3328

Green flashes then tv turns off


or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.

Toshiba 42hp83 plasma power supply problem?


I had the same problem. It turned out that one of the cooling fans get dusty and does not work. I opened the back of the Toshiba plasma TV and cleaned the failed fan, and it worked like a champ.

Takes about 5 minutes for picture to appear... Then every one to two minutes the picture disappears. It comes back on for 1 - 2 minutes then repeats. When set if first turned on, the stereo/stand-by light (red) flashes on/off until just before picture first appears .if your tv is very old than it might be due to crt getting weak crt base loose loose contact in power supply thanks
