SOURCE: Hello There!, Where can I get a T.V. Picture
You could try KOTHARI ELECTRONIC HOUSE 75, Sadar Patrappa Road,, Bangalore - 560002 (Karnataka) India Phone(s) : 080-2223351 Should cost around Rs.2500-3000. But, as the model you are mentioning is pretty old, is it worth replacing a Picture Tube? Think about it

It sounds like the magnetron may have
either failed or is not being supplied with the extremely high
voltage required to run it. YOUR
SAFETY IS PARAMOUNT This is a job for a professional but if
you are safety clued up, here's instruction. Load
test. A
simple safety test.
Make sure the !!!!any
capacitors are discharged!!!!! before attempting any sort of
repair.
Check the door interlock switches first then the high
voltage diode with either an AVO model 8 or moving coil meter on high
resistance range for short circuit, (DVM's won't show the fault!),
the capacitor can fail and go short circuit, the feed fuse on the
primary of the high voltage transformer and then finally, the
magnetron is best checked by substitution.
Hope that helps.
Place 1/2 litre of water in a glass container.
Measure the temperature of the water.
Place in microwave and heat
on full power for 1minute.
Measure the temperature after it has
stood for 1minute.
If the temperature difference is more than 9
degrees Celcuis the magnetron is working and producing about 700Watts
of heat.
If your microwave is labelled with 900 or 1000Watts. That
is about right.
If the temperature is less then the magnetron is
not working properly and may need replacing.
This
a only a rough guide and any doubts you should consult an authorised
service agent.
