If you feel you have isolated the problem board, you might check here for a replacement:

One very common problem encountered on many Philips models, old and new, In some cases, the SSB board has to be replaced as the resistor on the PCB on the back of the CRT had to be fixed. In other cases the Y Sustain board had to be replaced. If the problem is not due to these two issues, then the capacitors will need to be replaced as they only have a fixed guaranteed life. Thus, it would be wise to take out an extended warranty on Philips due to this common repair issue which often occurs after the limited warranty has ended. Or you could just call your local repairman. There are lots of websites on how to fix it yourself on google. There could be many reasons. Hope this helps!

This is quite tricky as it was working until last night and suddenly stopped receiving signals. What can happen wrong?
Do you have any other Player or other HDMI cables to try out. Sometimes the cables would be damaged or PC may fail to detect the HDMI.

Try this out from Philips helpdesk where there is new SW and FAQs are available.
