My Philips Magnavox TV model: TS2779C221 has a failed video. Screen
looks bright along with the retracing white lines. I don't have a
service manual, but just thinking whether I should venture into
component level trouble-shooting. I believe that it could be just a
matter of a failed capacitor or a dry solder. I had done such things
several years ago and am aware of the safety issues. The other easier
option could be to replace the chassis. I appreciate if anyone could
share a similar experience and suggest me where I could buy the
chassis (27K800 7591) and how much it could cost?

Thanks

Point #1, Chassis replacement is not the easy option as there would be many
alignments required. Plus the set was designed to be repaired to the
component level, if Philips had any Chassis available they would have been
on special order for authorized servicers to fix the oddball problem that
could not be repaired effectively under warranty. Most complete Chassis
from Philips are in the $300 range except for the RPTV sets.

That kind of failure is a simple matter to troubleshoot the crt voltages,
crt drive waveforms, video output supply voltages, etc in order to find and
repair the problem.

Thanks David, I appreciate your response. I looked at the alignment
thing, but couldn't find anything that I could adjust, except for
focus and VG on the output transformer. Things have improved a lot
over years. While the new set itself didn't cost more than $295 three
years ago, I am trying to understand why anyone would buy the chassis
in the $300 range. If I am not sure of spending my energy at component
level, and if the chassis is either not easily available or expensive,
is buying a new TV the solution?
