I have a WS65807 model proj tv .... I'm looking for part number 930B868001

Other than cleaning the three lens inside and the mirror it may be the age of the set.

Short answer: No.

The board and install will cost you more than an LCD/LED flat screen TV.

Sorry for the bad news, but you will save space and electricity with the new TV.

Next problem: Trashing the projection TV.

That board has been discontinued for several years now. Ebay may be the only place you may still find the Signal board your needing.

Pop sound shows that some thing went wrong inside TV and most probably any part got busted.
Let me know model number of your Sony TV and does its standby red light blinking? if yes, how many times it blinks between 3 seconds interval.

It is available in Part Store, click that link and see board image and price info.

The problem will be the deflection board (left hand side board when looking from back of unit.Part number is 258762 is no longer avaible thru rca but you can contact tristate module or pts electronics-you can even google the part number

The Color Signal on this Model Series travels across three boards before being sent to the CRTs. The 3DYC Board, Signal Board and the Terminal Board. Most likely, the 3DYC Board or the Signal Board is causing the problem. I have had intermittent solder connections on the 3DYC Board to cause no color problems. This Board plugs in and is located on the left front of the Signal Board as you look from the rear of the chassis. If you feel you are not up to the task to work on the set, call a Mitsubishi professional. To find one, call Mitsubishi at 1800-332-2119.
I hope this helps,
