No red light - no power at all.
Suddenly our TV won't turn on. The red light that is normally on when the TV is off is also not on.

The red light shows on the TV but the TV is not powering on
Does your TV have a power switch? Most TVs do, but sometimes - as with the Sony Bravias - it isn't easy to find. It can easily be switched off accidentally.
my tv was dead unplugged it for a half hr like you suggested and its back on ! thank you lots
Power within TVs in general has 2 forms (for lack of a better way to describe it).
1) Standby power - This is usually 5V and is there to respond to a remote. The presence of this is known by a red light that is seen from the front of the TV. If this is not present, a remote won't work and most likely the TV won't turn on at all. (This is what is being reported here.)
2) Running power - This is what is used once the set turns on. This is triggered either by pressing the power button on the TV or on the remote. In both cases, the internal "computer" is told to turn on the TV. Problems with this power supply usually result in the set clicking on and then off, no picture but sound etc.
Since the reported problem here is no red light at all, I would be looking for a more obvious problem with the power supply board. For example: a blown fuse, a defective rectifier diode in the standby circuit etc.
Further investigation is required to determine the exact problem. If you are not comfortable working on electronic devices, seek a professional service shop for help.

I have a Sony XBR-43X830C There is No standby light and the screen stays off when i try to power on the tv from the buttons on the back of the tv or the remote. I have tried following every tutorial i could find(holding the power button and volume down for 30 seconds then plugging or unplugging tv) i have tried every theory... I have also used a multimeter to check for power on the fuses and diodes and dif places throughout the circuit boards inside the tv. Not sure what I should look for.. Please help
