Question about ViewSonic N2750w 27 in. HD-Ready LCD Television
I have a N2750w with no CCFT lighting up. inverter has tested O.K. and the display shows content via flashlight test on screen.
the P.O. had problems with the orig. FSP204-2F01 psu and installed a new FSP204-2F02 by cutting off the 2 main wire harnesses that go to the psu and hardwired them in. ( Yikes ! )
the result was all other functions O.K. except for the above no CCFT and sold it to me in disgust, including the orig. problem psu
if anyone has a VS10576-1M ( mine has build date Sept. 2005 ) open and handy, I could really use some info.
1. is a FSP204-2F02 compatible and if you got one to work in this model, could you give me the CNS connector pinouts to wire color code harness connections? ( I want to check the P.O. wiring job and he left no schematics and can`t offer any help. )
2. if someone has the orig. 2F01 in place, could you give me the same pinouts and wire codes for the orig. CN1 CN2 and CN3 psu/wire harnesses? the P.O stripped all the harness to psu connectors.
3. with pinouts/codes in hand, can any local repair shop rebuild orig, psu?, or should I send it to FSP ? ( if they still do repairs )
I would feel better with the orig psu and connectors in place if possible.
the viewsonic service manual gives no detail and
I asked viewsonic for the above and have had no reply.
there is a chance the actual CCF tubes are gone, but this psu issue seems the logical place to start. if this site allows, pictures would be perfect.
Thanks for any "light" shed on this,
`n` Best Regards,
Tom in the Dark

I just had a viewsonic supply all apart with a blown capacitor, I believe c36. q7 a surface mount npn transistor on the solder side of board was shorted. Replaced cap and transistor, set works fine. Also, check all your electrolytics on this board as they sometimes swell and go bad.

do you have your tv opened at the back?
it is best to get the model number of the inverter to ensure proper replacement.
let me know and I`ll help you get to the inverter if you need help.
its really not that hard.
