Bit of a long shot, but i thought i'd ask.
Our 6ish YO Bush CRT TV has been losing the picture, but the sound remains. A quick thump to its side normally brings it back with a pop.
Took the cover off it last night and it seemed quite dusty, losts of dust on cables and boards, but it looked like it had been attarcted by static, you could see the dust was perpendicular to the wires etc.
Is that normal?
I've given it a good dust and hoover to clean it out.
Any ideas why a thump would sort it? I couldnt see anything obvoius loose, checked any cables to make sure they were secure, had a look at the PCBs for dry joints etc. Is it just getting to the end of its life?
Any useful advise or thoughts would be appreciated.
