Vk20 speaker fault

Post by punkdaddy » Sun Mar 18, 2018 8:54 pm

So I just bought my son a cheap second hand vk20 as he fancied coming out with me

Problem is the speaker only works when the headphones are connected

So I have no sound or both working simultaneously

Any suggestions?

Thanks

If you're competent with basic DC wiring, you'll need to check the jack socket, jack plug and also ensure the speaker wires are not loose/shorting out whlst giving a general visual inspection for and obvious or potential faults. The alternative is to seek out a competent person to do this for you. Regards ss47

Almost certainly the contacts on the phone jack have corroded.

Sometimes you can get them working again with some switch cleaner spray and inserting the headphones a few times. Sometimes not and a new jack will meet to be soldered in.

Don't use WD40 it dries sticky. It works in the short term but 9 times out of 10 it will fail shortly after and your back to square one.

Cheers. I have some contact cleaner I've used before. Will give it a go

At the top of this page is a link to 'MDF Guide', click it and scroll down to 'Posting Pictures' which should provide the solution! Good Luck. Regards ss47
