SOURCE: No power on Westinghouse LTV-46w1 Television

This kind of failure is very common; that is why I suggest that one should keep the old CRT TV, buy a converter and put them both in the garage or basement so they are handy when our s*e*x*y new sets go belly up.
With fair confidence I can say that the main power supply has failed.
If you want to try this on your own, it only will require the removal of a few screws and a flashlight.
- Unplug the set overnight. - Remove the rear housing  - Use some logic and these tips; look for a separate board with larger than average parts on it and seems closer to the power cord than others. This will be the power supply.
Check the board over for something that looks like a part number and record it. If you find more than one, one of them will be the bare board number, the second (sometimes on a sticker instead of printed directly on the board) should be the part number for the assembly.
Search for the Westinghouse service company nearest you and call them with this info. Ask if they repair these or just sell new ones. If it is the latter, don't pitch the old one, continue to look for a repair service that will take it on after you have the new one in place and can watch your favorites again. The new supply will likely cost between $90 - $150 and with a little common sense, most anyone can remove and replace these in the set. Expect any repair to cost about the same as a new supply; US technical labor costs more than Chinese assembly labor. 
These supplies can be as reliable as the primitive older type but companies refuse to use the high-grade components necessary to give them a long life so they fail much sooner than the old, less efficient kind known as 'linear' supplies.

SOURCE: new Sceptre 37" LCD TV does not turn on

I just got a 42" komodo by Sceptre, same problem, except "SCEPTRE" showed on the screen. I was sent a USB key program to insert in the service slot in the back and it reflashes the bios. This is old news for you but maybe new for someone?

I just checked and my tv was purchased with a credit card that gave a double warranty. I have to fill out some things but it should be fixed eventually...

The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.


If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

My TV won't turn on, how can I fix it/

Switch it on directly from the TV. Try changing channels. If the screen stays black, open the casing and find a push-button switch near the tube or in the panel. It will reset it. If you don't, have it serviced from a certified tech.
