Help,
My Ferguson W7022U TV won't come on.
The red standby light is working and the set monentarily comes to life when
I use the remote.
However during the usual delay that the set takes to check all is well
before the CRT fires up, the set switches back to standby and it makes the
usual 'plop' in the speakers as it did when normally switching off.
Over the two days before completely failing it took to switching itself off
and on at random.
Can anyone point me to the 'STOCK' faults.
Thanks....
Dave

which chassis is this? if you intend to solve this yourself or ask
for assistance, you'll need that info. Likely a Thomson. Look for
something starting with an ICC or TX on stickers on the rear of the
chassis.
You will also have to take some measurements and do some basic fault
diagnosis- start with the most likely - remove the horizontal
transistor and connect a 60-100 w bulb across c-e, see if there is b
+: if so, measure it.
chances are the set is protecting itself due to a short, often in the
horizontal /line stage or on the vertical/frame output chip - 2
common culprits.
Anyway lets not get ahead of ourselves - post results of the tests and
we'll take it form there!

Note that there are safety hazards involved , if none of the above
makes sense to you then don't play about, take it to a tech. You could
screw it up beyond economical repair or kill yourrself if you go
poking around!
