If you have not done so, not indicated here, inspect the lamp first, is it intact?

SOURCE: model 50HM67 - will not

Hi,

your TV is having a power problem. The power supply board is defective that's why the TV won't power up. Its receiving power but it cannot transfer the current to the necessary part of the TV because a capacitor, diode, etc may have been faulty. Until these bad components are replaced, the TV might not come on.

This may have occurred as a result of power surge/irregular power supply or excess power that may have entered into the TV previously.

If you know about TV repairers, I would suggest that you open the TV and read the power board/panel with a meter, detect the bad component and replace it. Take note that TV stores a lot of current that can shock, so leave the TV for a while before you open it.

If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you.

I wish you good luck.

Yes. The Yellow LED blinking 3 times is a normal boot-up, but if it keeps doing it -- it needs the firmware "update" (which is more like a reload because it got corrupted.) The problem is, no one talks about how to do that. (there is a PDF and firmware on toshiba's website, but it lacks some crucial details.)

My friend gave me his 42HL167 after this problem started after a power event during a storm and I managed to fix it by reloading the firmware.

I posted instructions on my website at:

Once I figured out some of the facts, it was a breeze...
