New lamp still blinking red light

If the unit uses a ballast for the lamp, it could be that it needs replacement of the ballast.

Something you might want to look at:http://sites.google.com/site/sonylcdrptvproblems/lamp-overheating-issue

Are the red and green lights blinking at the same rate or not? If the green light is blinking every 3 seconds and the red light is blinking every 1/2 second, the lamp door is not properly secured. If both lights are blinking at 1 second intervals, try replacing the lamp. If a new lamp doesn't solve the problem, the TV needs service.

I hope this helps.

I have PJ 550 exact SAME PROBLEM replaced bulb NOTHING

The color wheel needs replacing. Thats causing the whining and it will also make the lamp light blink.

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.

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.

am sure the lamp is fine. first thing replace the lamp thermal sensor if this does not work check the lamp ballast (aka) lamp power supply.

Could be an LCD drive board or a ballast. This is what to expect from free advice..... A guess. If you pay good money for a set why not get a factory tech. who knows what to do to solve your problem. I don't do LG warranty right now, but I did when your set was new. Here is a free gift. Start by having someone test the lamp tempurature sensor. It is a very thin black wire with a small fuse-like thermistor with heatshrink tubing around it. It is mounted on or around the lamp and can be purchased at any major consumer electrinics distributer. Good luck, Russmann.

same problem as others 3 blinking green lights then orangey colors then 3 red blinking lights afterwards shuts down fan runs for about 2 mins solution check your door cover for warpage or deformed just a bit under set screw there is a push in switch try and push it in with q tip while holding turn on tv if it works then that door is deformed and defective change it

thanks for solving my issue tv works again very helpfull thanks
