Toshiba 14AF43 No Signs of Life

It went from working one day to no signs of life the next with no other symptoms. Line voltage is getting to the board, the fuse is OK, no obvious signs of a problem on the circuit board. I don't have a schematic, but I do have a VOM and some electronics knowledge. Can you help?

    Are you referring to the voltage regulator? Do they use a three pin regulator in this TV? What voltage should I be looking for? Thanks

Toshiba tv 57hx81 red power light blinks no picture and no sound


you wont believe this.. i tested all the pico fuses, and found them to be ok..tested for voltage to the fly backs, went on the check the rest of the "power board". things like voltage regulator, resistors, any thing that might look suspicious. so far the entire board had no signs of electical shorts. this lead me to think maybe a lose solder joint (a common fault with this circuit design). WELL you mite ask how did i test all those connection joints? I guessed, well almost, using a rubber handle screw driver, i gentle tapped the major components, included the snap in terminals. seems that where i tapped the tv came to life and then died..by viewing those areas the solder was dull, with slightly discolored surface around the solder joint and easy to spot . ..."there is picture & sound" when resoldered all the pins that i suspected as defective. testing several hours now..please throughly check, clean and resolder any suspected joint. hopefully this will work for anyone with a similiar problem..

HP notebook will not restart after closing cover overnight


Think it went into hibernation. Unplug from a/c adaptor, and remove the battery. Let it sit for 2 or 3 minutes, then plug in a/c adaptor and turn the unit on. It should reboot like new.

Polycom Fx doesn't power on or show any signs of life


Try disconnecting the ISDN module and then cycling the power. If that doesn't work speak to your support provider about repair costs. Ultimately you may need to replace it because of its age (it might be End of Life and not available for repair)
