Question about Sony Projection Televisions

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? My Sony KCD (KDF-46E2000) TV turns on and off, and even turns back on again by itself.  It is not covered by warranty.  Any ideas?

Sony TVs come with a one year warranty on parts and labor. Call Sony at 1-800-222-SONY They will find a local company to service this product.

These TVs have a self-diagnostic screen that a tech can access to help solve the problem. Your problem could be any number of things including the fan(s) stopping, the ballast board failing, Q-box issue or none of the above.

When I turn on my tv, 20 seconds later it shuts itself off and then it comes on again and 20 seconds later shuts off again. The screen never comes on either.


hello, If you can turn it back on with the s momentary key or power button:
When it shuts off, do you need to push the power button once or twice to get it back on? Also, does anything else about the picture or sound change as it warms up?
If once, then the controller is shutting the TV down either as a result of a (thermally induced) fault in the controller or it sensing some other problem. Monitoring the voltage on the relay coil (assuming these is one) could help determine what is happening. The controller thinks it is in charge.
If twice, then the power supply is shutting down as the controller still thinks it is on and you are resetting it. A couple of possibilities here would be low voltage or high voltage regulation error (excessive high voltage is sensed and causes shutdown to prevent dangerous X-ray emission). A partially dried up main filter capacitor could also cause a shutdown but there might be other symptoms like hum bars in the picture just before this happened. Clipping a good capacitor across the suspect (with power off!) would confirm or eliminate this possibility.
If it uses a pull-knob (or other hard on/off switch), then this may be like pulling the plug and would reset any abnormal condition. NOTE- It require you opening the back cover of the television. Goodluck

Last night the set just turned off by itself. When I try to power on, the power light comes on for a second and then it shuts itself off again.


I am having this exact problem. The TV turned off by itself and now when I try to turn it on, the power light stays on for a sec and goes of with a click sound.

Any TV experts who can HELP?

Sony KDF-50E2000 shuts down and blinks repeatedly twice.


The 2 blink error is a temperature error and the 6 blink error is a thermal fuse error. You may need to unplug the set and get you a can of canned air, take off the back lower cover and blow out all of the fans inside the set.

KDF-46E2000 turns off then back on by its self


* Most common would be a couple of capacitors in the power supply that are not letting the proper voltage to the lamp.
* The lamp itself is not working properly.
