Question about Televison & Video

1 Answer

I have a 40" Toshiba rear projection TV that has just lost sound & picture. The red power LED is still illuminated and you can hear something like a relay occasionally click at the back of the TV. Any help is gratefully received.

You are probably hearing a relay that is connecting, then disconnecting power because of a fault in the power supply.
Most modern sets try to control damage when a serious fault occurs by shutting down instead of allowing something to burst into flame.
You need on-site help with this one.

Toshiba projection tv no picture


You will need convergence work to this unit. Not cheap.(Not recommended for DIY unless already experienced in this type work). Might contact a local servicer experienced with Toshiba & see if they can give you a quote over the phone. Be sure you are sitting.
This is probably a good time to consider entering the 21st century & look at LCD or LED flat screens.

Rear projection TV is made up of a TV, optical lens and a screen. So picture projection problems are from the small TV tube. Take off the back to reveal the TV and see what could be replaced?
