How to replace projection lights in 42' TV?

My 42' Sony went completely red after being on about 30 mins.  I went in the back and feddled until I wasted liquid from the blue light.  Turned it back on and it showed a beautiful picture for about 4 hours.  Then went green.  Where can I find a blue light to replace the one in the back of the TV.  I'm sure that is the problem and my TV will work again for another 4 yrs.

Re: How to replace projection lights in 42' TV?

Hello mdmaxwell,

The CRTs are usually what they call a matched set, meaning if you replace one you should replace them all this is going to cost you about at least $400.00. The liquid you felt was coolent for the blue tube, by the way I hope you cleaned your hands after touching that stuff it is a kin to glycoalochol which is poison. I would suggest as a place to begin to look for the part or parts (I suggest replacing all three CRTs to manitain the matched abilities of the tubes).

I hope this helps
Thank you,

Changed lamp and TV won't turn on, power light flashes 3 times

Red light blinking 3 times shows problem with lamp cover.
Lamp cover is not fixed securely in your tv after lamp replacement. Lamp cover is first thing that was removed to replace lamp, check lamp cover and make sure its back in place properly.

TV has gone into "protect mode" to do just that to protect against the damaging failure that has been detected, you will need a servicer to diagnose the failure. Good luck and Merry Christmas!

Tv will shut off and red light will flash 3 times

If its Sony KDF-42WE655 TV that goes to standby and LED blinks 3 times then check Lamp Door that seems not fixed properly.
That happens when lamp replaced in TV.
If its different model number TV, let me know exact model number.
