I will be happy to assist you with your problem.
Please give me the model number of your unit so I can pull details on your particular device.
Your help is greatly appreciated. I've searched the internet for answers and found nothing useful so far. These things are just too expensive to go out this early. It's only 3yrs old. My 20" Symphonic tube tv is 7yrs old and still working. Anyways,
I did not notice any change after changing the bulb. The info on the unit is:
Sony LCD projection TV
Model #: KDF-42WE655
Serial #: (NNN) NNN-NNNN LA3
THank you so much for looking into this and hope to hear back from you soon.
I hope this helps. Please let me know if you need any further information...Good luck.
