My Toshiba CT 8002 won't turn off standby. When I press the power button on the remote, it clicks as though it will turn on, and then clicks straight back to standby. Any suggestions? Thanks in advance! :)

It will be best to replace the power supply regulator board as card basis.

SOURCE: Power on problem for My Syntax Olevia LCD TV 23"

I have a 24" Olevia LCD TV. Same symptoms (Stdby LED is on, press power and it flashes off, then back on). The USB cable to the Service Port also worked. But being of sound technical mind, I figured this means that the PC is supplying the +5v to the circuit. What I did was disassebled the TV, carefully disconnected all the cables, and opened it up to reveal the circuitry. I looked over the circuit and noticed the 1000uf/16v capacitor at position CS21 was failed and bulging. I removed the cap, tested it and verified that it was indeed failed. I went to a local Radio Shack and picked up a 1000uf/35v electrolytic, after all, the value is what mainly matters as long as it's not lower voltage than the original. I replaced the new CS21 capacitor back in the circuit (it is polarity sensitive, so pay attention to what the original mounting position is). I reassembled the TV and Viola! Works! No need for the USB cable to the Service Port!

I hope this helps someone!

SOURCE: the red standby light flashes and when the power

One of the boards (module) has a short on it, and or the power supply itself is failing.
The service center will find the fault using the process if elimination. They will replace the bad boards or modules as required to get the set working again.

I cant figure out which button is for the code search on this remote


It should be channel up button. Just keep pressing it, allowing 3 seconds in between presses. Once your television turns off, you have found the code. Then press enter, and try turning your television back on. (Note: not all televisions will power down. Some may only change the channel)
