Question about Sony KDF-E42A10 42 in. LCD Television

Sony KDF-E42A10 turns off/on and does not respond to remote

Bought this TV in 2006 from Circuit City . TV will turn off power light blinks for about 30 seconds then it comes back on. At first this happened maybe once a night now it happens about 6 times in 1 hour. Circuit City has been out 3 times and cannot resolve the problem. They have replaced the lamp twice and still not fixed. Since they have not seen the problem there is no problem. I went on line and found that we needed the software upgrade. Sony came out did the upgrade and problem still exist.
Any one have any ideas or advice???

    Opps forgot the "other" problem... TV will not respond to remote, can't adjust volume, change channel or even turn the TV off. Try to turn off using the power switch of the TV and will not turn off. In order to get TV to respond need to unplug and plug back in.

    Both problems exisited before the upgrade. But the not responding to the remote just started about a week ago. We have a another repair person coming next week who stated that maybe the lamp ballister may be bad. Hopefully the 5th visit will be the charm to get this TV fixed.



    I don't think the upgrade was done correctly. He plugged in a flash drive to the USB port and the lights on front of the TV blinked red , orange for some time. When I asked how would he know when the upgrade was completed he stated that the lights would stop flashing and a solid green light would appear. That never happened - after 15 minutes he removed the flash drive turned the TV on and within 5 minutes it shut off by itself. He did the upgrade again and this he said that when the upgrade is completed the orange light will flash. So after 10 minutes he removed the flash drive left. 20 minutes after he left the problem returned -- TV would not respond to remote and could not turn off using the remote or power switch on TV. And within 1 hour the turning off/on returned.



    Thanks for you advice

The software still needs to upgraded properly. If you unplug the TV for 5 Min the plug back in and turn does it work

Well your orgional post sounds like the set was overheating.. The second comment sounds like you have a bad firmware installed.. So who ever upgraded it, didnt do it correctly or the main control board for the tv is shot. Did you have the same no responce prior to the upgraded software?

Hi,
Please make sure lamp cover is fixed properly as it was removed to replace/ check lamp in tv.
If lamp cover is not fixed, tv will not turn On and red light will blink 3 times.
Thanks.

Why power/stanby blinks light red


how many times does it flash? The back of the manual will usually tell you what the flashes mean. Try this: unplug tv from power. While unplugged, hold the power button in on the TV, not on the remote! Hold for 10 seconds. Replug the power and try to power it up. If you get no picture, you need a repair. Contact the manufacturer for an authorized servicer.

THE POWER STAND BY LIGHT IS FLASHING RED 4 TIMES


Anything less than 5 blinks is major trouble. More likely vertical IC and circuit failure. Picture has been muted or turned off by TV. If Stand By light was blinking 5 times the Stand By might have came out self-diagnosis function or mode.
Contact Sony Service Tech for service adjustment to fix problem.

Sony KDF-E42A10 rear projection TV. Won't turn on.


Start by changing the lamp. If you got 5 years out of the old one, count your blessings, most folks only get three. The lamp is designed to be replaced by the consumer. Ebay will carry a replacement for you or you can get it directly from rivervalleyelectronics.net. They've got good prices. The lamp door is on the back. Its really easy, give it a shot.
