[Fixed] Re: Toshiba 46XV540U problem
Replaced main board bought from eBay ($40, was for 42xv540u). The TV started up fine and stayed on. The display looked weird. In system mode, I changed panel parameters to the proper numbers for 46xv540u. Now the TV is fixed.
Good luck guys for your own broken TVs. No direct help here but some hints I got from reading other posts did help a little.

Re: Toshiba 46XV540U problem
On the board the Zener diode is MTZJ27A, the zener voltage is 24.26-25.52V. So it looks like the audio voltage is correct.
Now I see my BL_DETECT is 3V when off and 0V when light is on. It seems opposite of what it should be. Can anyone confirm?

Re: Toshiba Regza 37A3030D - clicks on then off
My 46XV540U has the similar problem. I think mine does have backlight. It is very light though. With the back cover off I can see the light coming out of the edge. Mine seems to have all the proper voltages and the voltage changes as I expect except may be the audio voltage is higher than marked 18V.

Re: Toshiba 46XV540U problem
Not sure why but the 18V_AUDIO pin on the S-Power board (PE0563B) actually gets 21.6V. If I press the on switch the voltage may go as high as 25.2V. Is this normal?
Anyone knows what STOP_FAN is for? Is it for stopping the fan or detecting a stopped fan?
Thanks.

Re: Toshiba 37RV530U No power
I use the latest AutoDesk Design Review. It works but you have to turn of the WHITE MASK layer and all the layers that draws a line and circle to each component....

I think I may have a similar problem with my 46XV540U.

Toshiba 46XV540U problem
I have a 2008 Toshiba 46XV540U LCD TV. I fought with my 4-year-old daughter one day. I tried to turn it on with the remote and she wanted to turn it off with the button on the TV. At the end she won.
Once plugged in, the TV's yellow light blinks 3 times, pulse, blinks another 3 times, pulse, then blinks another 3 times. After that the green light turns on. I can hear a click inside. I see the fan starts to spin and I can see the back light is on (not very bright but appears to be on). After a few seconds, the TV turns off, fan turns off. I can use remote or power button to turn...
