First thing I would try is a firmware update/reapply.

Could try to reset, one thing to try, unplug tv for 5 minutes then plug back in. another thing to try, hold down power button for 10 seconds then release. 3: with tv powered on unplug from outlet, if condition stays the same, go with a firmware update if possible.

Thank you will have to go with a firmware update. Would you happen to know where I can get the firmware from had a quick Google to nothing I can see at the moment.

A lot of times its hard to find, I'm pretty sure the manufacturers take them down off their sites pretty fast, I think their "stupid logic" is if you can't fix your tv you will turn around and buy another from them, when sometimes thats all it needs. A good thing to do for every tv owned, that is if the firmware is still on their site, would be download it and keep it in a safe place, where you can always access it.

Guess you could contact toshiba, tell them you are not able to get the update over the internet, maybe they will email it or something?

Try this, I think the last letter in your model is B right? so you would use B. http://www.dl.toshiba.com/tsb-dtv/NA.../40RL958B.html

Re: Toshiba 40rl958 power issues

Well I tried and tried the firmware update and still no response.

Re: Toshiba 40rl958 power issues

If you followed the update procedure just like directed and no luck, I'm thinking it's a faulty mainboard.

Check if you have 12 volts on each side of the fuse on the tcon board, fuse will have a label next to it Fxxx, negative probe on a ground.

Re: Toshiba 40rl958 power issues

I t may help if you upload good clear pictures of the whole back side of the TV showing all the board and then good clear straight shot of the whole top side of the main board.
What kind of Voltage testing have you done on the power supply board and the main board? Results?
