fsp035 power board mA

[quartz]

Hello, recently repaired one of these successfully (from info on this board, great but think the board may be worn out a bit (some faults came back after a few months), so bought a new one for £12.

its for a viewsonic VX912

original fsp035-1PI 01
replacement fsp035-1PI 01Z

the new board has 3 jumper settings for 6.5mA, 7mA or 7.5mA

supplied setting is 6.5mA

from where the silkscreen mA details are printed i imagine it's something to do with the high voltage supplied to the screen. can anyone confirm the mA ?

Correct, the mA rating tells you how much current will be supplied by the inverter to each CCFL. Bigger screens have bigger CCFLs and thus require more current. The voltage supplied by the inverter is constant, though.

A CCFL inverter is a constant current source. The voltage will vary depending on the temperature and age of the lamps.
