Black screen but still here shows


only about two possible reasons bad solder connections or the picture tube is not getting the 6.3 volts for the filaments in the neck of the picture tube.

If set is opened carefully and turned on look to see if 3 faint filaments are lit or not. If not that is your problem.

No video only sound on CRT TV


possible no filament lit in the neck of the picture tube (there are 3 and not real bright as source is only 6.3 volts.

Possible no High voltage but most that have sound have high voltage.

You are going to have to remove rear cover to LOOK--be careful and let me know what you find, if no filaments are lit it will be a easy fix and should be easy to find---if no filaments let me know.

Hi Louise.
My HAZ upright kettle did the same thing recently.
Sounds like your element-tube has a rust-hole, which allowed water to enter the normally dry and cozy filament area. The water that seeps inside hits the red-hot filament, vaporises to steam which violently expands out of the pinhole.
Remove element, check for corrosion, renew.
Hope this helps. Clive.

Sounds like the ground wire for the battery is not making clean contact. Trace that wire and clean both ends and the area it connects to the engine block. Good luck!
