Doesn't sound like a lamp issue to me. Do you see this on all inputs and if not what input do you see it on and what is it connected to?

Well, i had a look at the back of that Toshiba TV - make sure that the red, white, and yellow cables are hooked into the Video-1 slot of the Toshiba and that the Toshiba channel is changed to Video 1.
Then check your nameless DVD player and make sure the red, white, and yello cables are all hooked to OUTPUT slots that are in the same column or row - if I had you DVD manufacturer and model #, I could suggest some additional steps to check. Also, make sure your dvd player is in dvd playback mode.

Projection TV no picture flashing horiz arcs across top of screen sound okay


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.

When the tele is on the screen has lines through it (black and white) and flashes in between the blue screen and the picture display.


OK so you are saying that you can hear the TV even when the TV flashes to a blue screen right can you hear a diff noise that it has never made before

Picture loss after picture begins to flash. blue and yellow light


Most likely the lamp is dying. Try replacing the lamp before calling a repair tech. What does the Owners manual say about the blink lights?

Toshiba 43" Rear Projection tv (Just show's Blue Screen)


Hi Chris,
It sounds like you have a tuner problem. Usally the set will turn blue if there is no signal to the set, which is first generated from the tuner. It could also be the processor on the main board, but I would look at the tuner first.
Good luck and I hope this has helped

Flashing LED
<< Back to Quick Fixes Page
If your set all of a sudden won't come on, e.g., the screen is blank, but the LED on the under the screen next to the on/off switch keeps flashing, then there may be an internal fault on the set that needs to be reset.
To force the reset, try this:
  • Unplug the set and wait a few seconds
  • Replug and see if the video returns
Whenever the set senses an internal fault through its monitoring circuitry, it essentially shuts down the set. The flashing LED provides the indication that a fault has been detected. Removing power to the set resets the monitoring circuitry. When plugged back in, the circuitry again does a check of the system. If it finds that there truly is a problem, then the set is shut down and the LED will again flash.
