    I just replaced the lamp also and I am getting the 3 blinking red lights.

    Someone on here is saying something about a micro-switch. Is that inside the lamp housing? Or is that the plug looking thing on the bottom or what? My replacement lamp came as a black unit that I cane only assume just screws in. Help me if you can.

The 3 blinks on this model TV means you have a lamp cover error. When you install the cover look at the tab on the cover and make sure it is making contact with the micro switch inside the lamp housing.

Tv light standby red just keeps blinking after replacing bulb


Hi,
If red light was not blinking before lamp replacement and after that it start blinking 3 times then pause for three seconds and again blink, check lamp cover that has not been fixed on tv or it is not fixed/ seated correctly there.
Lamp cover is first thing that you removed from tv to replace lamp.
Hope these info will help. If red light is blinking other than 3 times, let me know how many times it is blinking along with tv model number written at rear to provide you helpful info.
Thanks.

3 times standby red light blinking shows that lamp cover has not been placed back properly after lamp replacement.

The on lcd little light blink six time


The standby light blinks to indicate problems with the TV. Six blinks indicates an internal problem, I suspect with the lamp. I recommend contacting a Sony repair shop to vacuum out the TV and replace the lamp. Installing it yourself has no bulb warranty and you cannot vacuum it out without taking it apart. Lamps are $250+ each...

Tv wont power up Standby light keeps flashing.


First step in any Sony LCD projector repair is bulb or lamp replacement. Fixes 95% of problems.

Taking apart and trying to measure things without a known good bulb is a waste of time and effort.

I try to turn my Sony Wega 42" Rear projection lcd tv on , but the power light goes once to green then blinks 3 times in a row, for a number of times before it just goes to red, when it shuts off...


I am posting here because I read the response the other person gave you.

Are you saying the set does not turn on and the red light blinks a sequence of three red blinks several times?

Confirm actual model number---3 red blinks is an error code---Get me Model number (KF50WE610?) and I will try to give you a simple answer---If it is what I think it is---3 blinks may have a easy repair that anyone can do.

Buzzing/screaching noise when turned on, standby light blinks and then lamp light blinks


It sounds like a bad lamp. Replae the lamp firts, but there is a chance you have a bad lamp driver also.
