    I have the same problem as rg18. The TV will turn on and then randomly the picture goes black. It will stay off for 10 seconds or so, then turn back on and keep going through this cycle. The screen also gets lines through it freezes the image for a second before it goes off again. It will occur both with DVD player and Sat. When the screen is black, it will not turn of, it is frozen and there is no sound ether. Any ideas, I would be greatful.

Tv power cuts on power light lit no picture then Tv turns it self off, when picture appears there's waves in picture and tv turns itself back off and on with no picture just black scree


Hi Patty
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.
If your TV, flatscreen, or monitor is more than 5 years old it is more like to have suffered a component failure.
Take it to a repair shop.

Tv turns on w/pic then pic dissapears light blinks 4 times


I have the same issue, we've had to change our bulb three times in less than two years. now we have 61" expensive paper weight. Our current bulb is less than 6 months old. The TV is only 2 years old and like i said this is our third bulb.

the blue light blinks 4 times. you get sound. then a few minutes the the picture returns... then it goes out, and the cycle goes on.

A solution to this would be greatly appreciated.

There is not much you can do to fix your plasma. Since the plasma is less then 1 year old, still under Samsung warranty.
I would suggest to call them to fix it.
Good luck.

We own a Toshiba Regza 42" direct view LCD TV. We have owned this since last November (bought as a Christmas gift). This TV was working great until last night (7/7). Powered it on and for a split...


Unfortunately there might no be a fix for this type of failure unless the LCD is open and perform a few measurements in the circuitry. Since the TV is less then a year old, I would suggest to contact the vendor or manufacturer to have it repair under warranty, most electronics devices carry one year warranty.
Let me know if you require further assistance.

The popping noise you heard it's probably a capacitor blowing up in the power supply circuitry. If the TV is less than one year old, still covered under manufacturers warranty.
Let me know if you need any more assistant let me know.
