I need to replace a 2275 MPX board but can't find any on eBay does other models have the same board I can use on 2275? Also my signal strength meter is completely dead sometime when left off for awhile it will work for a few seconds then go completely dead.?!

Why not just repair yours?
There is some info here.
There are several models that share this board including the 2325, 2240, 2240B.
The number on the solder side of the circuit board is YD2890003. You can search parts lists in service manuals for other models that use this board.

Is the signal strength meter failure due to this MPX board?

Could be. A DC voltage representing the signal strength comes in J315 from the IF amp, gets buffered by H316 (R374 sets the meter level) and goes out J316. If there is no DC voltage to the board (or the ground is missing) then the board won't function. Power (+14VDC) comes in on J304 if I'm not mistaken.
