Replaced bulb and the tv worked great. I turned tv off and could not get a picture. tv blinks red light on lamp.

Put lamp cover back on tv as it will push a safety switch inside then tv will turn On.
Lamp cover is first thing that you removed to replace lamp in tv.
Hope this will help you.
Thanks.

Check Lamp Fan if it stops running when Lamp trys to Light ,Then Lamp will not Power up,or Ballast Board itis what powers Lamp on.

OK...Did you replace the lamp with a Sony original? If you did, then carefully check that the door is closed properly.

Ballast Board its what turns Lamp on Call Encompass or visit their website. 1-800-638-3328

New bulb is just fine.
3 blink shows that lamp cover after replacement of bulb in TV is not fixed properly or not seated well in its position.
Put new bulb and carefully place back lamp cover in its position because lamp cover will press tinny safety switch inside that will send signal to system control of TV that lamp is installed properly.
Turn On TV and get vivid picture of Sony.
Thanks.

If the second light is blinking to orange or red, that is usually the lamp indicator light on an LG DLP tv. That indicates your bulb needs replaced, or something surrounding the bulb has failed (like the cooling fan for the bulb for example) IF you have a spare bulb handy, I'd replace the bulb, keeping in mind if you touch any part of a new bulb with your bare hands, you just cut the life of the bulb by more then half.

check the current maybe high voltage occur or due to loose connection high amper occur.

Hi,
Symptom shows Lamp is weak in result and causing restart of TV again and again. Your TV requires new lamp as per following part number...
A1085447A* LAMP BLOCK ASSY XL-2200U
It is available in Sony Accessories Store for $200 and replacement procedure is written in instruction manual of TV.

Always buy Sony original lamp for TV and avoid aftermarket / cheap lamp for TV safety.

ballast is not striking the lamp and needs replacing

this is a symptom of a bad lamp. for some reason it won't spit out a lamp error. shaking up the lamp will sometimes fix temporarily but you will find replacing to be the answer. if your tv has a fan error, you will get 4 red blinks.
