change the convergence ICs also check the resistors right next to the ICs as 1 or 2 of them may be open as well.

Afraid this is a common problem with Phillips, what happens is the coolant in the CRTs becomes contaminated, this is most common in the Blue and green, So what you have to do is have the coolant changed. Here at our shop we charge $250.00 for this. For most TV newbies this is money well spent. We have see coolant changes go horrible wrong, Anything from a coolant leak, broken CRTs, relay bad convergence after the repair, to the relay bad of a small leak that will destroy or burn your TV set down. Best bet is to get a repair shop that has the tools and expertize to do this for you

The adjustment requires disassembling the projector. It's not really something that should be attempted in the field.

It keeps overheating.

Is the fan set to run continuously? Go to the menu and see if it's set up to run. Also we have this problem with mounted projectors in our classrooms, we have to keep the room cool, and make sure the projector gets circulation of air.
Hope this helps.

The projector does not operate the "lamp" led blinks in green and turn red after one minute. The switch on button does not replied.

either it's overheated or needs a replacement bulb.Do not cover this unit with anything as it will prevent cooling down..

How do you get the bulb out of the Phillips ProScreen 4750?

Hi there

There should be a lamp door at the bottom of the Projector that you have to unscrew before you will be able to take out the lamp.
