My Philips 32PFL5604H TV has had a sound problem for a while. It originally occurred when I the TV was turned off for less than an hour then turned back on the sound would not work. If left for over an hour and then turned back on it would work fine. The problem seems to be happening more frequently now and rarely does the sound come back on. Can it be fixed or is it time for the bin.

Lg 42lh30 Tv runs well for awhile 20 minutes to an hour, then a click sound comes out of just the right speaker. Then the TV freezes and none of the buttons work on the TV. Once I cycle the main power switch the tv will not turn back on, thought a red light shows that power is available. I did some minor troubleshooting and found when I disconnect the T-Con from the main board, I do not ever get the clicking sound, my buttons always remain functional, and the TV seems to run fine (I can hear the

I have a Samsung 46 LED 3D 200hz tv. Normally the tv is fine but lately the tv, after a hour or more of viwing, tends to lose signal.

The sounf and picture are fine again, but then I lose sound and picture a few seconds or minutes later. At first I thought it was my Foxtel playing up but when I do have picture and

The picture will come on when you first turn it on but after 15 minutes or so it fades away. The sound still comes out but no picture. Sometimes it will come back on on its own after a while and then go out again. If you turn it back off for 15 minutes or so it usually comes back on. We already bought a new tv and that one works fine so its not the cable box but I would like to put the old tv in my room.

I have a 9 yr old D52W20 RCA tv. It turns on and is fine for about 35 minutes. Then it turns off and then right back on again. it takes about 15 seconds from the time it turns off for the picture to reappear. It will stay on anywhere from 5 to 30 seconds before turning off and back on again. I had a repairman come in and he said it was not the capacitors but said he needed more information. At that time the unit would be fine for a couple of hours before it would start acting up. Any thoughts
