Sony LCD KDF-E42A10 Television

don't leave it on and have it looked at---most likely is if it uses a lamp that may be the problem but if not it may be in the power supply.

3 blinks indicates lamp door is not on or has not been reinstalled properly. This also could mean the lamp door switch has failed itself. Try removing the lamp door and putting back on, if that doesnt correct the problem then I recommend having the switch replaced.

Plasma and LCD TV sets are prone to having capacitors in the power supply section fail. This is the most likely cause for the probem you describe. When capacitors fail your will commonly see one or more of the following symptoms.

• No video, Power light is on or blinking.
• TV is making a clicking noise.
• TV takes a while to come on
• Screen is very dim or flickers.

Again, You can get a power supply repair kit with the parts, detailed instructions, and support from sites such as www.TvRepairKits.com . Or just click here to see more details on their kit.

Here are pictures of capacitors...Notice that the ones below look bloated. They have failed and will need to be repalced.



Capacitor being replaced! Fairly easy DIY fix.

red light flashing seven times

It is symptom of weak lamp that reaches at end of its working life, replace lamp in tv to fix the issue.
Lamp replacement procedure is easy and written in user manual.
Thanks.

I disagree with info given by expert.
Pop sound would be broken lamp in tv, take out lamp from tv and check it, replace it if found broken.
Usually lamp got broken at end of its working life span.

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.

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.

Please count green flashes and let me know.
There would be pause in flashes so count between pause.

You have to schedule an appointment with Sony to come out and they install firmware into the TV. It is free. Go to www.updatemytv.com
