Re:
I have the 51 inch of this model and I have found that usually it give you some indication before going completely out. Like color problems, sound, or just video disappearing. Most of the time it will be the convergence amps going bad, but you should have seen some color distortion. If not then it could be the vertical output. TDA8177 needs replacing and check caps around and diode, If not this then look for open fuse in HV line to crt's. Also power supply fuse like 1900, 2004, 1300, etc.

Here is th elink to Philips support page fro your TV. Turn on the TV, if it is working you should see the light of the back light lamp. If you are changing channels and hear audio from different channels it is a good bet you lamp is open. http://www.p4c.philips.com/cgi-bin/dcbint/cpindex.pl?ctn=60PP9202/17&slg=en&scy=US
I hv philips 21RF vardaan TV ,there is sound on AV channel. and the picture is blinking. even some menu setting have changed.. i tried using the service menu but cudnt understand anything. 2 new av channels have come.. av2 and front which were not present before. sound is not coming even on the other channels but picture is fine on them. only on the av1 channel it is blinking., the philips technision had solved this prob once by pressing some code by remote and i don't know the system code
the problem is in your tuner section or video if section
check for its proper voltage.
if you are not tech. person get the help of tech person
it is not a major problem.
