While watching my LNs4051Dx TV the screen goes black but sound is still on. I power off and on the cable box and TV and picture comes back but only for 30 minutes or so. Three years ago I repaired the capacitors on this TV with great success. Anyone have a fix for this problem?

Panasonic model PT-50LCX64A started shutting itself off a couple of weeks ago. Then a few days ago it wouldn't turn on. I have unplugged it for a few minutes and then bypassed the power bar straight to the wall and tryed it. Still nothing. It blinked green for about a minute then went to red. I read online that there is code for the number of red blinks but it appears to be blinking red continous. The TV is about three years old.
The first thing I would check would be the status of the lamp. Did you verify if its broke? ...

I have a vizio vw37l hdtv20a. A few years ago shortly after getting it the TV made a sound almost like something popping, then just turned off. When i plug it in no lights come on or anything. It's been a few years, but I just decided to get it back out and try to fix it. Would this possibly just be a blown fuse? The TV was hooked up to my computer at the time also by the way.

I have a SANYO DP46848, 46 inch flat screen hdtv purchased about 2 - 3 years ago. The screen goes dark on the left side (top .25% is ok). It sometimes fixes itself after an hour or so. Sometimes you can fix it by placing your hand on the dark spot for 10-15 seconds. There is a thin horizontal line about 1/4th of the way down from the top with the top of line ok when the bottom of line area goes dark. LCD Controller? or Main Board? or Power Supply or the Panel itself? I have a picture if that

Hello, my parents bought a Samsung LNT4671F 46-Inch 1080p 120Hz LCD TV about two years ago unfortunately me and my brother cracked the screen about 3 months after we have not fixed it. Me and my brother want to fix it for them now.We're wondering the cost and where can we get parts etc..thr process basically
It is beyond any reasonable repair---screen unit is called a display panel and the most expensive part in the set---cost of this would (just the part) be more than a brand new set.Let it go, some people do sell sets damaged like this on EBAY ...

Hi, My name is Cristina Muller, I livein Trinidad. I bought a Akai LCT3285TA three years ago and now suddenly since a week ago when I turn on the TV I see the hair in blue and some backgrounds in pink, I tried to move the brightness and contrast and hue. When the blue on the hair or around the people disappear the colors are no more bright as I have to put the brightness almost at 100%
Do you know how to solve the problem ?
thank you very much for your assistance
I'm assuming that you have tried to cure the tv by reseting it from the menu and it didn't helped.The symptoms you describe indicate that the image processor no longer decodes the colors correctly. Since it's glued on the motherboard it means t ...

Hi, I purchased a Sony Bravia model #KDL-52S4100 two years ago. About 7 months ago when the TV was turned on there was no picture for 15 minutes or so, then when you turn it off and on again half a picture will show with larger images on the right hand side of the screen. Other times there is half a picture and then when you turn it off it will come on with a full screen picture. Once it warms up the picture is fine. Is there any inexpensive solutions here? Thanks for any help you can provide.

My JVC GM-V42UG has an intemittant line in the screen about 2 inches wide going from top to bottom. This happened when the unit waas 6 years old. At that ime, I took it to a shop and they replaced the power supply and charged me $600. It took 4+ weeks to get it fixed.
The set is not worth another $600 investment. And so, I thought if it a baord swap out and inexpensive, I would install it first before buying a new set.

The power supply board should be too easy for you to replace considering your credentials. All I need is the part number for me to find you a replacement. You will need to remove the back cover of the tv and locate the board into which the power cord ...

I have a Olevia 226T and it keeps randomly shutting off. I tired unplugging everything and letting it sit over night but that only fixed it for a day. If I shut it off all day and turn it on at night it will work for about 40 minutes before shutting off. When I turn it off then and turn it back on it will only stay for 10-20 minutes. I have had the tv for about 5 years and never had an issue before. Any help??

I repaired my convergence problem on an RCA HD52W59 a couple of years ago by soldering a jumper.I found the fix here. That's when I joined, and found many fixes since! Now, all I find are kits for sale. Is it possible to do this for a Magnavox 51M392H, and if so, where would I jump?

My tv, and also my mother in law's, which were both bought at the same time 6 years ago, started turning off by themselves. They won't turn back on immidiatly but if I wait a few minutes They will come back on. Not for long though, about 10 or 20 seconds or so. Seem's like the longer I leave the tv off the longer it will go without shutting down. Any suggestions? The TV'S are not at the same residence.
