Discharge the power from the set before you do anything. HIGH VOLTAGE!!! Look at the power supply. It will be in the area where your power chord is soldered in. Toshiba sets are notorious for the mosfet chips going bad. But your problem almost sounds like some bad capacitors. If the mosfets were bad, you wouldn't have any power to your buttons/LEDs. Replace all of the capacitors within the power supply section. They're cheap.

Hello! The picture on my toshiba cz36v51 is halved vertically, and has a duplicate picture on either side. Is that fixable? This problem occurs when trying to watch movies, cable, xbox...etc. Fixable or...


Sounds like you have a horizontal timing error causing the mirrored image. It is fixable but would require the main board to be replaced. The part number is 23783078 but appears to be no longer available.

After power button is turned on the led light flashes, and the only way I can get a picture is to bang on the front of the tv by the power button.


Sounds like you have a "Dry Joint" or bad connection, or even a faulty power switch.. this is a fairly common one... try a switch replacement first? Or look for a bad joint on or around the switch connections.

the internal bulbs have deteriorated...the manufacturers are real smart, these monitors dont last forever. So if repair estimate is too expensive then replace the whole unit.

I have a Toshiba cz36v51 that won't come on...


I do not have that make and model. However:

Some remotes have to have a code set that matches the brand of the tv. Your remote should have come with a list of brands and codes.

Alternatively, the instructions for your remote should tell you how to determine which code to use.
