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

I have a Vizio model E320Vl TV. after working for about two hours it shuts off. You can unplug it and wait about 10 minutes and it turns back on but will shut off again after awhile.


Sounds like The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electro-medical.blogspot.com/
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board...

My sony wega kf-50E200A tv keeps turning off. during each cycle the green light blinks 42 times and the tv comes on again for about 3 minutes and it happens all over again


More than likely the power supply is defective, but without testing and the repair manual that is just a guess, you make the decision to replace or repair the TV.
