I have a samsung LED tv that the sound works but picture goes on and off. Fixable??


Nearly every problem is "fixable", but you reach a point at which the cost of repair is so close to the cost of replacement that it eventually becomes fool hearty to do anything other than upgrade.AND, if you're thinking about fixing it and selling it, know that you can hardly give these TVs away. I listed a perfectly good, well kept, fully functional 50 in. Panasonic (720P) in classified for $100 - I had paid almost 1K for it in about 2010. I wound up giving it away to the local Day Report Center to watch training videos on.

My sansui television fell off my tv stand, it dropped about a 1ft to 1.5ft on the glass front but didn't break, sounds like it turns on but no picture, do you think its fixable?


You need to give it a shake and see if you hear anything loose.

respond with how this turned out.

Assuming its a CRT, something heave ripped away from the board on impact.
or the nack board on the back broke the tube.

the first situation is fixable, the second is not.
If its a small TV you should forget about it, the charge to fix it won't be worth it.

If you got a techie friend, you got a good chance.

Tv turns on with sound but picture goes away in 2 seconds


Your backlight controller is faulty. There may be faulty capacitors or faulty inverters. It needs to be repaired by a TV repair shop.

I have mitsubishi vs-45501 Projection TV and periodically the picture goes, has good sound. I let it rest for a few days and then it comes back on, then picture goes away, wait a few days and it comes...


This is quite technical because I've suspect the faulty on the ff parts :

1. Tuner
2. If Transformer
3. Leaky Electrolytic capacitor
4. eeprom
5. system IC

I've advice you to send it to the qualified service center because there will be a series of test.
It is quite fixable. First ask a quotation on the shop how much money you are going to spend on service fee plus parts because the parts above are quite expensive.

If your unit is under warranty then avail it because the manufacturer of your unit will fix it for free or a little charge only.

Thanks for using fixya.

Sounds like the lamp is going bad. They heat up, and shut down. Then when they cool off they start back up.
