Phillips 20GR1252/75B no picture

Hi all,
My TV Phillips 20GR1252/75B has the red light to say it is in standby and
seems to accept the remote signal to bring up the picture (red light goes
out) but it doesn't bring up the picture.
If you fiddle around trying different power and remote switch on/off it
sometimes comes on.

This isn't the first time it has happened and then I didn't have time to fix
it myself so paid someone. The repair didn't last long and cost me a
bundle - oh well, live and learn.

Suspect it isn't an easy fix and as I don't have a circuit I am not sure
where to look.
Has anyone a circuit or suggestion on where to start - power supply etc.
Any help appreciated.

Brian,
Well should I thank you for your welcome to this newsgroup.
I have an been working in electronics for 25 years (process control systems)
but agreed don't know a lot about TV's - have a bit of a clue as I have
fixed 3 computer monitors and figured it should be similar.
I kept the message short to make it easier about the fault.
The set has been back 2 times since the original repair - same problem each
time.

I only wanted to give it a try myself before I dump it.

Cool down mate the Freebee has no Freudian links - it was only to stop
spammers.

This is one of the worst chassis Philips ever produced.
To be honest, I would try a repair shop again -- just having circuit diagram
will not help. One needs experience with this chassis.

Common faults include horizontal transostor failure, inductor next to FBT
fails, zeners in PS, FBT itself, etc.
