Check the latching relay to switch on the tv.

    I don't see a latching relay on the schematic. Is there a number on it?

I HAVE A TOSHIBA SATALITE A135-S4427 TURNED IT OFF ONE NIGHT WORKING FINE, THE NEXT DAY IT WONT TURN ON. I HAVE POWER THRU THE CORD AT ABOUT 18+ VOLTS BUT NO INDICATOR LIGHTS OR POWER TO COMPUTER. HELP?


Try removing the battery and power supply, hold the power button for about 10 seconds then just plug the power supply back in (not the battery) and see if it turns on.
Holding the power button with no power supply can discharge any stored power in capacitors.

No picture but sound on Toshiba 46h84


If you feel comfortable enough, you can try replacing the pico fuses on the power supply board. Test them with a multi meter very carefully.. these sets have up to 5000 volts and care should be taken, even by a professional with the back panel removed.

Relays wont click on when plugging power to deflection board 1730c toshiba 46h84


have you checked your fuse? Will the relay click when you press power? You may possibly have a bad relay or the bridge rectifier diodes could be open.

Blue crt assmbly maybe?


its very possible that the blue CRT is horting the set out. Heres how you can test it. Remove the speaker grille and access panel behind the grille and you will see the crts. remove the blue crt circuit board from the end of the blue crt and make sure it isnt touching anything then try powering up the set if it doesnt shut down then you have found the problem and you will need a new crt. or you can switch the blue circuit with the green and try it iwth the blue on green and the green on the blue then if the screen turns green before shutting down you will know that its a problem in the blue drive circuit and not the crt. lety me know if you need further assistance.
