Viewsonic N2750w power supply unit problem

Hi,

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

SOURCE: No picture on N3250W viewsonic

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.

When turned on the power led lights up, and the screen flashes for a second and then goes dark. All i can see when the screen flashes is AV in the top right corner. what could cause this?


It can be the power supply or inverter board, main board problem, need troubleshooting first, common problems are power supply and inverter board.

My VA712 does not turn on, when supply button (mains) not from front panel, switch ON it shows blank screen (no sign of turn on) but when repeatedly switch ON & Off it Turns On & shows the display....


bholesir, If unit covered by ViewSonic warranty, USE IT!!! The units "switch-mode-power-supply" is in need of service!! Unit WILL require inspection and repair of possible bad (poor quality soldering) soldering of electronic components to the prinded circuit cards and or need replacement of bad (poor quality) electrolytic filter capacitors on the unit's "switch-mode-power-supply"/"CCFL inverter circuit" that have failed!! Do a visit to YOUTUBE for "LCD monitor disassembly" and "LCD monitor repair" so you can familarize FYI with what is inside your monitor, and possibly make a decision to do a DIY repair or contract out the work to a local TV/LCD monitor repair shop. If your pocket is deep enough, maybe you will repair and buy a new unit, keeping VA712 as spare unit for a rainy day. Read more of my responses to other owners in my FIXYA profile for more options not mentioned here. Good luck with repair. 12fixlouie

No picture and ligh just plinks


kathleen2002, If no picture, then do flashlight test! Six words and no punctuation will not garner much help on fixya here darlin. Tell us more. We need to know how old the unit is and or number of hours use. Did unit work perfectly the day before? Does this monitor get power from a "black lay on floor brick" or does it power up direct from wall outlet? When it worked last, did it have a bright, crisp image displayed on the LCD panel? If you are not a technician familiar with LC display technology you will NOT be able to repair it. As a consumer/user, your options are very limited. 1. NEC warranty if covered. 2. Cash+old monitor swapout with NEC for a refurbished 1550V w/new CCFT/inverter/SMPS. 3. Local Technician to refurbish your unit with new cold-cathode-fluorescent-tubes+Inverter supply repair if required and test unit's switch-mode-power-supply. 4. OR just trade up to a new and younger model. Bye for now. louie12fix on fixya or lmistyrel @aol.com

I have 2 ViewSonic N2750w and and they both have black screens


i have repaired several n3750w viewsonics .. that may be similar to the 2750 .. in my case all the failures were caused by the same faulty part in the power supply .. the power supply has a 48 volt supply at about 7 amps .. the design uses a syncronous rectifier .. these are normally not used in supplies with that high a voltage out .. syncronous rectifiers make sense when the output voltage is low .. like 3 or 5 volts .. the parts are designed for that range .. but in this supply an IC is over stressed and fails frequently .. you might hear a chirping sound as the supply cycles thru an overload condition .. i modified the power supply to eliminate the syncronous rectifier and replaced it with a single shottky diode .. dissapation goes up slightly but reliability goes up a lot .. i have written an article on this. if anyone needs it i will try to find it . ..

Viewsonic N2750W...wheres the inverter?


I'd say it's more than likely built into the power supply on this model, take the back off, the inverter plugs into the back of the panel on both the left and right, if not, you can take photos of it with the back off and send it to me and I'll identify it for you

You have a bad inverter board.I have seen this in quite a few units,various brands.Call electronica 303-322-3037.This is the only place i have found that can supply the part at a resonable price.The part usually comes as a display assy.
