Question about Sony VPL CS4 Multimedia Projector
Power cable is good and so is power supply tried in other sockets. Not getting even a stby light. Please help.
Ok - So i finally located the problem for the Stby lights not coming on......
Mine had the same procedure as all the other posting this - Could take up to 48 hours for the light to come on but this time only the whistling sound from the fan house on the front was present.
So i dissmounted the power supply located on a standing card at the back of the housing and found the faulty component :)
The solution for this problem is a IC in that board called IC MCZ3001DB changes this and all your problems with the projector not starting will be solved.

Kudos to kowe for this solution!
My CS4 had the same no power and no light problem...eventually got to where it wouldn't power on at all. I located the A1316568A PCB after disassembling the unit (this board is located near the rear of the projector when looking at with the lens pointed toward you). The entire board is expensive to replace (i.e. over $200), but all you really need to do is replace the MCZ3001DB IC on this board (provided you have some soldering skills). I found this IC on eBay for $20 (3 pack), and some 18-pin sockets @ hobbyengineering.com ($.99 ea). You don't want to solder the IC directly to the board. After replacing this IC, wallah...the unit powered right up! If you need any specific help with this repair, just email me...hi_bandwidth at yahoo dot com.

The board is right underneath everything, near the back. I agree with kowe, regarding the IC number.
You need to lift out the whole optical assembly to get at the relevant circuit board A-1316-568-A (but note that mine had a sticker over the circuit board number with a different number on: ...-576A) - It is mounted vertically along the back face of the projector, but you need to remove the optics to access one of the two screws that holds it in place.

I have the excat same problem. I have been through the whole projector, but could not find the A-1316-568-A that you are writing about. The close I can come is A 1316-575-A. Where exactly is it placed in the projector, and how does it look like?

I can confirm to you that the problem is caused by the A-1316-568-A since i had two CS4 in shop for repair and was hable to swap boards. now i will let you know if i can fix the board because it sells for about 300$ Canadian

Check out the fan cover switch just behind the vent grill.
next to the input panel. you do have the vent grill fitted ....
the switch is almost invisible but must be made by the
peg on rear of vent grill

Ok so I don't persay have a final solution, but maybe something to help you troubleshoot the issue. I tore mine completely apart, checked the lamp, the fuses, any loose connections, all of that. When I plugged it in I got the same problem as before..BUT this time I left it plugged in overnight (about 20 hrs maybe) and finally the lamp/cover light came on. So our problem might be as easy as replacing the lamp. I will check this theory at some point, just need to get the money first. I'll let you know when I replace it.
