I have an older Panasonic 26 inch tv the screen was a bit warped at the top off and on then the picture shrank to a bright horizontal line then went black the sound remains.

This is a common vertical circuit failure and if you had distortion at the top before,that was the capacitors in the circuit failing which filtwer the voltage to the vertical ic which has now failed as well.A lucky fix maybe just resolderingm the ic pins! A reputable shop may able to repair for less than $100 or I can guide you further to fix your self if you have technical expertise.

I have re-tuned my TU-CT20 Panasonic set top box several times, successfully in that I have a new list of stations, but every time BBC1 and BBC2 are omitted. It starts with ITV1 at channel 1.

If you have all the cahnnels updated then you will have to manually edit the station list and change the order of the channels. refer to your manual for instructions.

AWA set top box STB232 connected to Panasonic LCD

Loss of sound is often a SCART connection problem. Check that the SCARTS are pushed in securely. Or if the SCART is old, it may be faulty. Try a newer one, or one that you know is definitely ok.

Panasonic model CT-36SL13G TV

Your problem is most likely the thermistor , or degausser, is going bad. It is a little black box with pins and says D1R5M on it. It can be found by following the wire from the degaussing coil around the picture tube. The location number is CF803( i think)the Panasonic partnumber is D4DF1R50001. Also, I believe your fuse is 6.3A not 3.6A.
