I have a mitsubishi vs-50605 and it keeps shutting off, why?


Most likely case is the set has developed bad solder connections which is normal with heat and age---moving the set may have speeded this up.

With sets of this age what I do is get the chassis unbolted and pulled back so it can be tilted up--so bottom of board faces rear of set.

Then start looking for bad connections in power supply and a few other areas.

This presumes you can get it apart and are able to look and resolder poor connections.

Set may be too old to invest money in a shop repair as a lot of the parts it uses are no longer available---other side of the coin is these are much more trouble free than newer Plasma and LCD sets and last a lot longer..........

When it shuts off and the green power light goes off, press both the menu and input buttons on the front of the set (not the remote) and hold both for about five seconds and release.

Power light will blink a two digit error code like 2 blinks and then 3 blinks and repeat it several times.

What is the error code?

Samsung HLN507W turns on for about one minute then shuts off, three blinking lights stay on in front. It is not the lamp, nor the blue lamp cover switch for sure. I unplug it and immediately turn it on. It always does the same thing: comes on for 1 minute, then powers down - there is no wait time in between unplugging and powering on. All fans seem to work and I cleaned the dust out of it. Help.

My Sony KP-51HW40 isnt staying lit up.


You should be little bit more specific. How many times does the standby light blink once the set turns off? That is an indicator for the problem with the set. Any colors showing brighter than others while the set is on? Please give us more to work with. Also, before you are removing panels, please make sure the unit is unplugged!

TV turns off


It sounds like you might either have a bad power cord or you might have an over heating issue. Some times the TV will automatically shut off if it senses a fan issue or it starts to overheat. What technology is your set? DLP, LCOS, DILA...? If its under warranty I'd suggest to get someone out asap to take a look at it.

Panasonic Flat Screen TV turns off by itself


If your unit was blowing fuses you must have had an overload somewhere. Your post is not clear. Does your unit run ten minutes after unplugging and replugging it? If it does then there is still a partial short in it somewhere which causes it to shut down for protection. It could be anywhere. Some detail on what happened prior to the fuse blowing would be helpful for diagnosis. You do not sound like you would have the expertise to troubleshoot this unit. I doubt there could be much wrong with it and the cost should be minimal. Find a reputable repair shop to handle the repair. Good luck.
