Question about Televison & Video

1 Answer

Ive got a two year old magnavox 37in lcd tv and just last weekend i was watching and the picture went out. i turned it off and back on and it was ok for about 3 min and the picture went out again. now if it is turned off for an extended period it will work fine for about 25 min and then the picture goes out so if i turn it off for a while then i can watch for a while. i sent it to repair shop they said it needed a new mother board for $ 350. then two days later they called back and said $ 475. i think they are trying to take me, its not worth that much. can you help? ive got electrical experience, low voltage also

Could you try and do static discharge everytime this happens? Disconnect everything from TV and press power button and hold that for 20 seconds. Turn TV back on and see if this will work.

If this will not work you will definitely need new mainboard which is quite expensive. You can get good price for mainboard on e-bay but this may take time while appropriate model for acceptable price will be available. But this worths to try.
Just register on www.ebay.com and search for appropriate motherboard type (based on TV model)
Making any repair works on the mainboard itself requires industrial type tools and eqiopment as mainboard may consist of up to 8 layers of internal circuit that is just impossible to mess with in home environment.

I have a Vizio 37" HDTV that recently started losing the picture. The sound has been on continually but the picture now flashes steadily but mostly remains black. It went out one day, came back afte


it sounds like a backlight issue. It could be as simple as a few bad caacitors. If you already replaced the set and you just want $$$ toss it on your local Craigslist as a parts/repair set. There's always TV shop owner and parts scavangers that will buy the set as is. Price wise, if the set is in good condition and come with remote, and pedestal, I would ask $60 as is but you may get more

Tv went off and won' come back on.


Most likely you will have to replace the power supply. It is a very common problem especially in newer electronics. You can test it with voltmeter or multi-tester. They tend to get worn capacitor inside the power supply due to cheaper parts

Toshiba LCD TV screen went white and stopped receiving pictures


If it is under warranty begin the process by calling Toshiba warranty department at 1-800-457-7777. Demand that they send you a prepaid label as shipping a TV is expensive.

Philips 60" rear projection needs warm up time


Sounds like your regulator ic is about to go, not an expensive repair but you have a good thought about buying a new set. If your fluid has never been changed I bet it's due also. Give the choice serious thought.

No setting or troubleshooting can fix this. TV needs service. Sounds like a control board or buffer board went out.

Magnavox 15" LCD TV


If the LCD only has coax, it will never display a HD picture quality. However, the Comcast HD Box will still display a picture using the coax connection. So, you could watch any HD channel, but the picture quality will not be high definition.

Vizio 37in lcd yellowed picture


Mine turned red. Had a bad HDMI cable. TV is missing part of the video feed. Try a new cable but first make sure old cable is in all the way.

TV WENT OFF BY ITSSELF


This may denote a proble in either your switching powers supply or your Horizontal section derived high voltage power supply. These are both very dangerous sections in your television. My next question is important; do you have a background in electronics? If not I would not advise you working on this problem yourself and that you take the TV to a repair shop for servicing. If you do have some background in electronics, I would like for you to make the following obeservations: What was the TV doing (it actions)prior to it going out? Did you hear any sounds before it went out like buzzing or crackling? What do you hear when you try to turn it on now, clicking? These questions are just to develop some background into what might be happening to your set. Thank you, Shuttle83
