You have a bad solder connection in the Vertical deflection circuit. Try re-soldering the vertical output IC and the Vertical yoke pins. You may have to look over the Vertical circuits with a magnifying glass to actually find the bad solder . A hint if the solder looks dull re-solder it.

    trace the wires from the yoke on theCRTs back to where they plug into the chassis. There will be 6 plugs 3 horizontal yoke plugs and 3 vertical yoke plugs. Horizontal are usually larger plugs where as the vertical are smaller.

How to replace power supply

unscrew the screws on the back and open the chass. then draw a map about the connections where those power cables went into inside the chass. then unplug all the power connections and unscrew the screws on the back which fasten the power supply to the chass. remove other components if necessary to alow space for the power to come out. then replace the power and anything else in reverse order and reconnect the power cables according to the map.

No raster, no audio, CRT filaments lit, 20KV high voltage, B+ 136V.

most likely you are missing one of the scan derived power sources; most of these sets when HV is present produce some secondary voltages for other things---look at diodes and resistors around the flyback (HV) transformer--if you find an open resistor there--follow it back to the diode that supplies it---also try to check all the smaller voltages from the main power supply

When you plug in the tv the tv appears to come on and you here a click. The timer light stays lit red and the screen will not come on.

There is a fault in your tv, if this is a crt type could be at high voltage section.HOT is shorted , flyback is shorted or both. But atleast your standby power is working. The click sound could be the relay in action.

sounds like the LSB is defective as that controls all the high voltage and deflection circuits. If you go to the following link and leave them a email with your model number they should have a LSB board for your model.

resolder the vertical IC that is whats making the CRTs go blank. Its a safety issue where the CRTs blank when there is no vertical deflection. Just resolder the output IC that should cure your problem

Volume buttons stuck inside

hi , first i want to say that the tv is not a game it is hazard set very high voltage inside so if you don't have any experience please dn't try to , but you can do it your self just took outlet off and took case off and try to draw the chasses towards you to behind then look inside to the place of the buttons you will see aplastic tips which will push the volume switches that are soldered on the chasses and with your fingures try to push out the plastic tips to relocate it to the original state it is too easy and the please try to be away from the cable that is fixed to the screen cause high voltage is it, refix chasses and cover and give me high rate insted of £40:) regards

The high voltage should be around 29.5 KV and not fuctuate between 20-30 KV that would indicate a high voltage regulation issue then. Are the filaments lighted up in the neck of the CRT? If so then yes you are probably looking at a low voltage issue such as a 12 volt source or a a/v switching IC issue.
