Red light on power button flashes, but no picture....blank screen

Son was playing xbox 360 and said there was a loud click and the screen went dark. Currently, the small red light on the power button flashes. You can push the power button on the TV or remote with no effect. The little red light continues to flash but no picture. All suggestions appreciated! Thanks, Bill

Re: red light on power button flashes, but no...

I would suspect a problem in either the backlight assembly, or the power supply that drives it. If it's the power supply, the part may be over $100.

Re: red light on power button flashes, but no...

I have the same problem with my 5 year old 42" rear projection Samsung. This is the second problem I had with it. The first one would have set me back $400. If I didn't have a service contract. I no longer have a service contract. I am going to dispose of my TV at this point (would be cheaper to replace with a flat screen these days) and will not be buying a Samsung again, stick to Sony or Panasonic for durability.

I have a Westinghouse flat screen TW-62021-K026G. When I turn the power button on all I get is the small red indicator light. Nothing on the screen, no menu or picture from any device.

I had that when my son switched the input to play his PS3. Turn on the TV. wait for 2 minutes. Press the input button on the remote. Mine was HDMI 1 that game me back my picture.

We own 2 Sony TVs. FD Trinitron Wega KV-27FV310 and LCD Bravia KDL 40S4100. Both have now lost 1/2 a screen. Top 1/2 on the Wega and left 1/2 on the Bravia. Our son plays XBox 360 on them. What i

On the WEGA the panel control module and possibly the left side planer board is done for. On the other sounds like the planer board on the dark side is done a well.
Get your son a Gaming type monitor cause this will continue to happen due to the higher refresh rates demanded on the gaming software.

TV will not turn on

Hi, It could well be the power supply that is in the back of your set. Have a repairman check it out. It's not a do it yourself thing. Good luck.

Heard a loud pop and screen went dark. red light on front of tv flashes 4 times

Plasma and LCD TV sets are prone to having capacitors in the power supply section fail. This is the most likely cause for the probem you describe. When capacitors fail your will commonly see one or more of the following symptoms.
  • No video, Power light is on or blinking.
  • TV is making a clicking noise.
  • TV takes a while to come on
  • Screen is very dim or flickers.

Again, You can get a power supply repair kit with the parts, detailed instructions, and support from sites such as . Or just click here to see more details on their kit.

Here are pictures of capacitors...Notice that the ones below look bloated. They have failed and will need to be repalced.

Capacitor being replaced! Fairly easy DIY fix.

Theres is powere going to the tv the light is red on the power indicator but when i press the power button the light stays red an no picture comes on the screen. so basically nothing happens when i press...

Power supply module will be the first place to look, look for bad DC filter caps for leaking/bulging tops. Then you will have to do in-depth troubleshooting.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

LG 26LG30 screen suddently went blank. Light flashing blue/red

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.
Please post back what you find.

I was playing my xbox 360 on my viewsonic tv and it just went off

From the symptoms it sounds like the TV requires an Inverter PCB.

This is the part that "lights" the screen.

I hope this helps.
