Question about Toshiba CN36X81 TV

1 Answer

TV turns off by itself after being on for 60 seconds

After turning off red standby light flashes. Have to unplug tv and replug before turning on again.

I think it is a power supply problem, but I am not sure. I had an older 30" toshiba with a similar problem about 8 years ago

Led blinking Three times means B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672.
Hope this helps.

    Disregard these instructions as they will not be applicable to your TV. I was to answer a sony problem but by mistake I pressed post.

I have a sony bravia 52" KDL52W4500 problem it has brokedown, goes on for a second then switches itself off again, red standby flashes 6 times

6 times red standby light flashing is an error code that shows problem of "Panel Det Error" It is technical term and experienced tech will understand it.
Possible cause of problem is either Power (G5) Board, Inverter (D5) board and/or LCD Panel (screen) itself.
Unplug tv from wall socket for couple of minutes to get it reset, replug back in and turn it On, if problem still not solved then it is not user level repair and you need Sony qualified technician to take care of it.

Tv keeps turning itself off and then back on. green power light blinks. If i tun it off when it does that the red power light blinks 5x repeatedly.


The Standby/Power light of the TV blinks when there is any internal malfunction in the TV.
The self-diagnostic function of the projection TV will cause the STANDBY light to blink or flash when the television detects an issue. The number of times the STANDBY light flashes corresponds to a specific issue. As per the two examples below, some of the issues may be resolved without the need for service.
If the STANDBY light flashes three times in sequence, the lamp cover is not securely attached. Reattach the lamp cover to resolve this issue.
If the STANDBY light flashes four times in sequence, the TV may be overheating. To resolve this issue, ensure that the back of the TV is well ventilated.

If the flash sequence is not listed above or the light continues to flash, follow the steps below to perform a power reset:
Try the following steps to check if the issue can be resolved.
Turn off the television.
Unplug the television power cord from the electrical outlet.
Let the television remain without power for 60 seconds.
Plug the power cord back into the electrical outlet.

If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.

If the issue continues to occur, service may be required.

Thanks for using Fixya.

My Sony Bravia will play for less than a minute and then reverts to standy. Any suggestions?

Please unplug tv from wall socket for minute or so,, replug back in and turn it On.
If tv still goes to standby itself than its standby light would blink to show an error in somewhere inside tv circuits.
Let me know how many times standby red light blinking? There would be 3 seconds long pause in blinking so count pause to pause to determine problem section.
