Question about ViewSonic VP230mb 23.1" LCD Monitor
We have about 200 of these beasts at the Hospital. After a year or so of continuous use, the power supplies are crapping out.
I need a schematic and possibly a parts list if possible. These things have recently become a main't responsibility for me.
You are talking about the Veiwsonic VP230mp right!
The supply is 12 volts at 7.5 amps.
Got some here we wit bad smps.
One had a bad PFC chip and the other has an intermitting start up.
Solution is trash the inside ps and hook up an externat one. Any 12 volt-10 or 15 amp ham supply will do.
Inside you have to trace out the main dc connection and solder to these and supply it wit outside supply.
If anyone knows the failure cause on the internal SMPS chime in.

We have detected one faulty chip (DIL8 box ref:13843 from ??)... The problem is that we didn't find any supplier for it.
There is another faulty chip that we found (DIL8 box ref:LM358D from Philips)... This one is easy to get on the market.
Do you have any supplier to propose for this component? Do you have spre component already?
Thanks by advance.
