Having problems with your Flat Panel Televisions ?

The TV seems to take ages to turn on, the red on/off light flashes and then goes off completely and the screen stays blank. It then switches on again and after a few seconds/minutes will switch back off. Eventually it seems to warm up and stay on. On occasion it will take up to 10 minutes for the TV to warm up and switch on. Once on there is no problems. I have not tried fixing this as I feel it may well be a job for a qualified technician. Please advise if the TV is safe to use, and what's need

Hi,

This is an indication of out-of-regulation in the power supply section. The very common caused of this fault is the leaky electrolytic capacitor in that section. It will drop the supply from normal voltage and will disable the unit.It needs a little warm-up to make itself stable but the symptom will get worst. Sometimes it has a bulged/dome at the top but not all, it is better that you have a capacitor checker/tester to determine its condition. Your unit will back to normal again if the leaky capacitor is isolated. Yes fixing the power supply is quite technical but in this case a little backround in electronics will be fine because electrolytic capacitor is the only parts that are going to be replace. If you don

My screen won't come on, however the blue light does come on to show it has power. Sometimes the screen just stays black, other times it seems like it's going to turn on but doesn't, meaning the screen lightens a little but it never fully comes on. This happens intermittently; when I unplug the power source for a small amount of time it sometimes fixes the problem and the screen comes on, however it often takes several tries. Periodically it just comes on right away. Also the remote frequently s

When power supply to TV exceeds 224V the TV switch off. It then tries to switch "on" again and will do so until the power supply to TV is lower than 224V. I ran a AC DC regulater to keep power output to TV as close to 220V. Then TV plays perfect. Aventually I unplug TV and go to bed. I have tried UPS's as well. Same problem. I think power supply unit in TV is damaged due to power surges. I replaced this 2 year old TV with a new one. Costly excercise. I still belive this TV can be fixed.

I have an old Toshiba CF27E50 chassis no. TAC 9515 that has had no problems until last week. I went to turn on the power and the red light flashes continuously, but the set does not turn on.

Can this be fixed or not?

I have a 4 year old WEGA Trinitron HD TV (model # KV- 30HS420) that over the last few months has been switching between full color and color missing green colorations.

Is there a fix for this or is the TV going?

I have a Samsung ln46c630 which was purchased in May 2010. For the last few weeks it has started to have a strobing effect. Switching the source sometimes fixes the problem. It will run fine for a while but the strobing returns. It is very obvious, like being in a disco. The strobing often starts when a commercial begins but then does not normally stop without the tv source being changed. Changing the source does not always fix the problem.

I bought an AVF AH080 Media Player and tried to connect it to my TOSHIBA REGZA 24PB1E, but it seems that it can only display the welcoming screen. I tried the same media player on some other monitors, and my AVF AH080 Media Player did its job well. So, the only safest conclusion that came from my mind is that it seems like the problem lies within the Toshiba Regza itself and not the media player. Maybe the monitor needs certain setup, but how do I do that? What I'm asking is how to m
