Hi.
If the light is shutting down, and you get dark screen for few seconds, then problem can be PSU, lamp or CRTs power board, or a digital board fault.
The board that supplies power to lamp must be tested. If that is testing ok, then the PSU higher voltage connector must be tested.
If the TV remains with a blank screen with light, then it is a faulty digital board, or depending on the model a problem related to optical group fault.
In both situations this is not a common fault, and testing and troubleshooting may be quite complex. Unless you are a technician, you should call the phone number listed on the owners manual to get support. If you are a technician in this case you may still need to follow the service manual to diagnose the fault.
Regards.

Try connecting different video sources to the TV such as a DVD player or a cable box using different connection such as HDMI or component cable to isolate the issue.

If the issue is occurring with any particular connection type (such as HDMI or component) then you may contact the manufacturer of the TV to check for the availability of any System Software update to address this issue.

Good luck!!!!!!!!!!!!!

It sounds like the projection lamp is getting ready to burn out, or there is a problem with the lamp driver circuitry. Something could be overheating. Make sure the ventilation ports are clean and clear and that the television has enough room for ventilation.

Screen goes blank, audio still works


I had this problem on my 42" Philips. Just got it yesterday and worked fine on the tv stand. As soon as I mounted the TV to the wall via wall mount system, I had the exact same issue you did. Figured it out today.

The wall mount was putting pressure against the center of the back of the tv (tv set had a slightly rounded back plate, and the mount was a flat plate). As soon as I put spacers (part of the wall mount hardware set) between the wall mount braket and the tv so there was no contact except at the mounting holes, the tv worked fine.

My theory is the pressure pushed the tv back plate against some board components which caused them to overheat (no air flow); or put pressure on internal connectors. I dont know.

Hope this helps, may not apply to your situation.
