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.

1 Check the M4 connectors for proper connection, and correct as necessary. 2 Check the fan for possible overload, and correct as necessary. 3 M4 operation check PWB-A PJ33A-1 (REM) D-5 4 Change PU1.
The temperature of the fixing assembly is abnormally high.
While startup control is under way, the reading of the main thermistor is less than 30 deg C continuously for 200 msec or more 1 sec after the start of power supply. While startup control is under way, the reading of the main thermistor is less than 70 deg C continuously for 200 msec or more 2 sec after the start of power supply. While startup control is under way, the reading of the main thermistor is less than 120 deg C continuously for 200 msec 6 sec after the start of power supply. The startup control does not end 30 sec after the start of power supply.
check the power supply unit first, if those output voltages are present and no voltage drop, which supply the mother board as will as for the hard drive. if power supply failure it will not continue to reboot the system. removed the power supply then repair it, however you can replaced with new refurbished power supply unit. hope this will help thanks for using the fixya good day.
Power failure as in whole house power failure? Or the computer's power supply failure?
Whole house failure, nothing, the computer will shut off and require rebooting, at which time you may receive a message the computer was not properly shut down, just continue as normal.
Computer power supply failure, same thing, nothing, except the computer will not reboot as the power supply has failed.
200 watt would mean it is a few years old so it could eb a few things. Power supplies can be prone to heat damage if never cleaned out. It's cooling fan gets plugged up just like your cpu fan. The ehat will kill off weak parts.
Generally what fails on these are the big power transistors (mosfets) and sometimes the power capacitors. Easy to replace if you can solder. There is also a fuse on the board that sometimes goes out. If you can't solder then its not really worth trying to fix as a new power supply is so cheap. You can find a 350 or 400 watt for about $20 brand new.
you will need to use the power supply that came with the zhone
router......other power supplies are not interchangeable.
make sure all other items that are pluged into the other phone jacks
have inline dsl filters....do not filter the router...if you have the whole
house filter on the outside of your house you will not need to put inline
filters inside ...
This power supply is a standard power supply that will handle 200 plus watts.
It can be replaced with just about any ATX supply and really would be a waist of time trying to trouble shoot it.
Any 24 Pin ATX supply will work just fine in its place.
