Question about Philips 60PP9202 60" Rear Projection HDTV-Ready Television
No picture dark screen,sound and system operational, tubes lit,no screen and focus voltage vertical circuit has complete negative and positive supply,is it possible if one of the crt's are deffective may cause similar problem?
The vertical circuit may have its positive and negative supplies, but is the output waveform correct? I have seen many of those TDA vertical outputs open up and cause exactly what you are seeing. The + and - supplies are there but there is no output. Replacing the IC usually cures the problem.
