Hi.

It is probably a defective ballast board or a faulty PSU. The ballast is the high voltage power board connected to the lamp.The PSU is the board that supplies power in different voltages to the other internal parts. One of the DC lines from PSU goes straight to the ballast. The repair is done testing the voltage from PSU to ballast. The job must be done by a technician.

My toshiba rear projection TV's picture just went black. Sound is good just a black screen.


high voltage is not coming up. possible fuse locates on power supply board on the right if you are sitting behind set with back off. if fuses are good, possible horizontal output transistor shorted. sounds horrible but easy repair

Check that you have not got an auto power off setting on. Check that the aerial connections are good. That the signal is strong from the stations it is picking up. Weak signals can cause the box to shut down.
It the box is very hot when it shuts down, you might have a fault on it.

The TV cuts off frequently. The screen is blank & no sound.


It is probable you have a poor soldered connection on the power supply board, hence the erratic timing of the TV going on & off. If you are competent with a soldering iron look for dry jointed soldering on the board. If not have a service engineer take a look at it for you.

Have you tried unplugging overnight? Sometimes mine gets screen garbage and that clears it up. Of course, now it says "Auto Scan Required" every time I power up. Maybe I should've grabbed that after Xmas 32" at Fry's for $400.

The solder joints on the vertical output IC have cracked. This is a very common problem on those sets.
