Question about Sony KDL-46S4100 46 in. LCD TV

1 Answer

Sony 46" lcd turns off by itself and will not power up again.

Twice in the last 24 hours my Sony has shut down with no ability to turn it back on. I tried switching AC outlets to no avail. I finally pulled the cord completely and went to get my multimeter to do some troubleshooting only to find the battery dead. As I went back to the tv and connected the cord I heard a click in the tv and it started working again. I then watched tv for about 2 hours and fell asleep. When I awoke the tv was turned off again. It remained off overnight and I was unable to turn it on in the morning. I then disconnected the cord for about 5 minutes and reconnected it. The tv turned on again. This tv is only 7 months old. What is going on?

If your tv unit is still under warranty, first you better bring it back again to the store you just bought it for warranty purposes, your tv has an internal problem, maybe manufacturer defect. Usually the cause of that is a shorted electronics component, say for ex, a mosfet transistor that is located at the power section, or maybe a capacitor that is leaky, and also an open resistor. if you don't know how to troubleshoot this problem, you better have your tv unit repaired by a professional tv technician.

Good luck

TV shuts itself off, comes back on, repeats


this sounds like the power supply is not functioning properly. Sometimes even the cooling system of the set will fail. Is it a projection tv or lcd,plasma? this has a lot to do with it as well because a lamp could be overheating. Let me know if I can help! good luck

My Sony Bravia turns itself off Stand by red light blinks twice.


If you bought it brand new from a dealer, I would take it back or have them come out and look at it. Less than a month old, it is still under the 1 year MFG warranty or the very best a 30 day one.

Samsung dlp hdtv turns itself off


I worked on one of these for a few weeks. if you dont mind a little inconvenience you can remove the back lower cover and defeat the bulb door switch and it will run. the last one i had like this we could not find the problem even with samsung tech support. changed many parts in the mean time. its heat related but the lamp heat sensor in our case was not the problem.
