Authorized sony repair center told me the problem was the Q Box. Ever heard of this? Part runs about 300 bucks. TV is out of warrenty as it is 2 years old. Do you think it is worth it to fight sony and get them to replace the part or just fix the TV?

Part Number is A1167541A, service rep called it a Q Box in the diag, however the web says its the b block assmy.

THE RED LIGHT THAT BLINKS IS IT THE LAMP BOX THAT THE RED LIGHT BLINKS IN OR THE STAND BY LIGHT THAT BLINKS ? IF ITS THE LAMP BOX THAT BLINKS THEN YOUR LAMP HAS BLOWN AND NEEDS REPLACED YOU CAN FIND THE PART # FOR YOUR T.V. FOR A NEW OR REFURBISHED LIGHT IN YOUR OPERATING MANUAL AND WITH THE PART # BUY A NEW ONE OFF EBAY,ALSO YOUR OWNERS MANUAL WILL GIVE YOU STEP BY STEP INSTRUCTIONS ON HOW TO REPLACE IT AS THIS IS A COMMON PROBLEM WITH PROJECTION T.V.'S IF ITS THE STAND BY LIGHT THAT BLINKS I NEED TO KNOW HOW MANY TIMES IT BLINKS AS THAT'S A SELF DIAGNOSTICS CODE THAT YOUR T.V. IS GIVING FOR THE PROBLEM AND FOR SONY THERESE NO CODE FOR 1 BLINK OF THE STAND BY LIGHT.

This model also has a paper filter for the Optic block that should be changed. No one ever said anything about it. shortens the life of the optic block if not changed.

Dark smudges/spots on my HDTV screen


The model indicated here Sony Grand WEGA KDF-50WE655 is a LCD rear projection and rarely if ever requires cleaning.

If black spots or such are gradually appearing the issue on this model is the optical light engine.

Set uses a LCD engine which the lamp shines directly into and heat from that very hot lamp can damage sensitive baffles inside the engine.

I would suggest also you contact Sony as they have on several models extended the warranty for this kind of issue---Engine is very expensive part and several of these Sony sets were involved in a class action lawsuit--hence they are dealing with them.

Do not take no for an answer if you want them to help you---the hinge that is sqeeks gets oiled...........

TV WONT COME ON AND THE LIGHT KEEPS FLASHIN RED AN GREEN ON THE STANDBY BUTTON


  1. If your Sony Wega will not turn on, the front green light blinks, you hear a faint whirring sound and the green light turns red and flashes, it probably means the lamp inside the set is no longer working. If you noticed the screen beginning to dim in the preceding days or weeks, this most likely is the cause.

  2. If the green light flashes and the picture comes on momentarily but then goes off, and the green button flashes until the set restarts, then the seal around the lamp mount is loose and needs to be refitted.

  3. If the picture on your Grand Wega cuts in and out and the green standby light flashes, both of the set's STKs need to be replaced. STKs are small chips on your television's circuit boards and are identifiable by their labels. The specific STKs used in your Grand Wega TV will be identifiable by the numbered labels on top of the STKs.

  4. When you plug in your Sony Wega and hear a loud popping sound, it's probably caused by a defect in the high-voltage circuit. Let the professionals take care of this one.

  5. If, after turning on your Sony Wega, you can hear your set but the screen is black, you most likely need to replace your projection lamp.

Hi, remove rear top cover, this will give you access to clean the unit, be advised you should use 2 people once you get all the screws out, the back is HEAVY because there is a mirror attatched to the rear cover(on the inside) and if you drop the cover it`s expensive to replace, good luck, BMW Rider
