We have a Proscan tv that the screen looks like a ''strobe light'', flickering all the time...can this be fixed?Also, a lost remote. When I contacted a tv repair place, they told me throw the tv in a dumpster, Proscan went out of business and there are no parts available. I see that KMart sells this brand..

Do not go to that TV repair place again!!! Thet are still in business.
PROSCAN WEBSITE: http://oncorpus.com/
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.

My coby flatscreen comes on and works but strobes flashing light but works good just with strobing light ! whats going on?

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

I have a 42" Proscan

It sounds more like a backlight problem to me. The first thing I would try before tearing the set apart is simply unplugging it for about five minutes and plug it back in. TV's do weird things sometimes and need to be reset. Odds are, if you have to open up the TV, there's not a whole lot you can do anyway. Check the backlight on signal and also see if your inverter is working. I would suspect that if you're strobing your backlight is probably dying. In that case all you can do is replace the panel; you could try finding a replacement backlight and installing it, but I wouldn't advise even trying this. Replacing backlights is quite a task if you're not familiar with televisions. Anyway, best of luck.

TV IS BLINKING LIKE A STROBE LIGHT AND WONT STOP EVEN IF I UNPLUG IT AND TRY IT AGIAN

Please make sure any device that is connected to the tv is disconnected.

Unplug the tv for 2 minutes. This will ensure all mechanics in the tv are given enough time to reset.

Plug it back in.

If the tv still strobes let me know.

FLICKERING BACK LIGHT

Sounds like you have an LCD tv with backlight problems. Check power board for domed capacitors and replace them. next check connections on the inverter boards. they are on the sides or just one side. Becareful there is high voltage output from these boards. If the cable from inverter board is not good to the screen you can get a strobing. the inverter boards may need replaced. or cales to screen may be bad. The panel also could be bad.

Problem with proscan 19LA25Q

Watching a movie tonight...and slowly there was odd behavior from the screen. No volume at first, then flickering, fragmenting and now, as the others only shows the red power. I have noticed some strange flickering the past 2 weeks or so. I thought it may be the cable, so did not concern myself too much. I believed that was the problem tonight as well. But the screen is definately not responding to the remote or manual button.

Thanks
