Look at the output transformers in the high voltagesection of your TV very closely. These transformers have been known to fail sometimes if you look closely you can see the burnt places on the circuit board under the bad transformer. These transformers cost about $30.00. This will fix your TV.

Hi, Our Sony Bravia TV model number KDF E50A11E is not working. There is a red blinking light flashes three times and then goes green and then red blinking again after about 3 seconds. Is this a bulb...


On that particular model I believe there is both a lamp indicator light and then the power indicator light. If it is lamp related the lamp indicator light (LED that looks like a sun in a cup...) would be on.

If the power indicator light is flashing red to green, that is a self diagnostic code, and you will have to contact an authorized Sony repair fascility for them to translate the problem. The error codes are not listed in the user manual, since most are not user serviceable.

My red light is blinking 3 times, the picture comes on and then shuts it self off and starts blinking. I have replaced the lamp and shut the lamp door correctly.


Hi,It sounds like an issue with the board that powers the lamp it's called the ballast.The ballast has a sensor that it detects when lamp is not responding or if ballast is not able to provide enough power to light it up,that's when you get the lamp indicator.This is the most common failure .When you put a new bulb in sometimes the ballast is not able to power it since it uses more voltage that what it was providing to the old lamp.The ballast is something easy to replace and it's cheaper than the lamp.Have a bless one!

Samsung hln617w dlp tv won't turn on. Red temp


Had similar problem. Thought it was the lamp. Examined old lamp but it appeared to be good. Ordered a new one anyway. Changed the lamp but the TV screen would not come on. It would make the usual noise as it was going to come on normally but it would cycle 3 times & then turn off. The LED lights in the front panel would indicate a defective lamp. Then read about the ballast. Changed the ballast & still same problem. Tried starting the TV without the lamp installed & noticed that the color wheel did not spin. Removed old color wheel & discovered it was broken. This appears to be the cause of all of my problems. I wish I new earlier of the test-turn on the TV without the lamp being installed & check to see if the color wheel is spinning. Would have save money on the lamp & ballast.

Sony grand wega kdf-e55a20 will not turn on when trying to turn on green light switches to red blinking light (this is not the replace lamp light)


Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast.Here's the instructions to replace it :http://www.fixyourdlp.com/guides/samsung/bp47-00033a.php But if you don't hear any strange noises,tv is around 6000 hrs,2-4 yrs it could be time to replace the lamp.The lamp you need is XL-2200.Have a blessed one!

I turn tv on...green light comes on but i get no picture or audio....then light indicator blinks red


Hello!
Lamp or ballast(if lamp has been replaced) is bad.
Explanation: green comes on: system works, waiting for light to shine into light engine: no light is coming out of lamp, system shuts down, then you see red! how to determine: pull the lamp out of the unit's compartment. Inspect lamp: bloated stem? shuttered? reflector is not shiny? Chuck it!
Lamp looks good or just been replaced: try ballast. Close lamp compartment without lamp itself. Make sure, door is shut, as well. Turn unit on and listen close to lamp compartment: good ballast will make a buzzing noise, then stop. You've got "red'! No buzzing: ballast quit. Needs major repair! Lamp must be good, for sure, to get to the last part of diagnostics. Conclusion: more, than 2000 hours of usage: replace lamp first!
Good luck,
Alex.

Picture cycles off and on


I replaced a burned out xl-2000u bulb with an after-market Philips bulb on my Sony KF60XBR800. After a fews weeks, I started experiencing intermittent black-outs with the "stand by" red light appearing. After a couple weeks it became intolerable. I then purchased an OEM Sony lamp and the problem has been gone for months. I read somewhere that the Sony circuitry monitors either resistance or watts and shuts the thing down for board protection. It was said that it is so sensitive it can can use only the Sony bulb. I'm a believer. If the bulb is going bad, i wouldn't doubt the protection circuit can kick in.
