TV not working when turned on

I keep losing this page so I hope you get this one. When I turned off the TV last night, everything was normal. This AM when I used the remote to turn it on, the green "ON" light on the front panel came on but nothing happened. There was NO blue screen. The screen was just blank as if it were not turned on. I could not get the green light to turn to amber (OFF) until I unplugged the unit. I tried the "Display" button and nothing happened. (green light was on). I have Comcast Cable which I rebooted several times, but nothing. I am sure it is the TV. Any ideas? Thanks

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

SOURCE: screen stays blank after turning it on.

Hello, The blinking pattern you're observing is a result of a heavy current load on the power supply. The power supply could be defective but more than likely the scan or sustain boards have a direct short on them causing the power supply to shut down and display the error. A technician will be able to determine where the load is coming from and replace the appropriate board or component. I hope this helps you. Joe Weibel CustomElectronics.Org

TURNED TV OFF LAST NIGHT EVERYTHING WAS FINE. TURNED ON TODAY - NO SOUND, ONLY STATIC

The tv is on the wrong input. Try running through the different tv inputs with the remote. If you have a cable box make sure its on. Hope this helps.

MY REMOTE CONTROL DOES NOT WORK AFTER DARK

bdale

You may have IR interference at night because of other items you turn on at night. Try leaving everything off except your TV and receive, try your remote to make sure it functions. Then turn 1 item on at a time, try the remote to see if it works or stops working. Once it stops working, the last item you turned on is causing the interference. It is then a matter of relocating that item so it won't continue to interfere with the remote functions. I hope this helps.

Quasar TV sp 2724E Loses the picture

Sounds like a failed vertical amplifier circuit. This is normally primarily contained in an integrated circuit mounted on a heatsink.
There are other possibilities along the line but the one above is the most likely.
Now all you need is a TV repair shop that is still in buisness.
