Retro stereo/ICE/radio trouble Sharp FM!

Experts in Radio Cassette/ICE types!

 

I bought a mid/late 80's Sharp radio for my Cortina shite, mostly cos the Philips didn't have FM. Nice thing with equilizer and digital tuner even put in its original box, once fitted initially fine, but the FM after a short while crackles/farts and fades out and nothing more than noise without leaving it depowered for ages!!! MW and LW still ok but the digi tuner seems to get stuck when in FM, couldn't even get it working again on sunday when I ran out of sunlight. Arrgh! /No FM, means no decent reception and no connection to my FM DAB player!

 

Whats the issue anything fixable?

 

 

 

Also in the case of a a permanent positive connection, would this go straight through to the battery or would you pick this up elsewhere?

 

Thanks for any help

Possible capacitor burnt out?

Warms up, circuit board changes shape a tiny bit and a broken solder joint moves and bye bye FM. Probably.

 

If it was mine and I wanted to try and fix it a good inspect of all of the soldering and rework every slightly suspicious joint would be the first step.

Good suggestions. It's annoying cos its otherwise great even the tape player works. Maybe dropped in transit or brittle 28 year old board/solders. Cheers.

So, I had another play today. One lid screw was stuck so ended up rounding it off and drilling it out! Great start!

Loosely plumbed it in again with lid off and FM lost again but seemed to crackle with nudge of on/volume dial or the equaliser. It went off again and was loads of noise like white noise with the equaliser just adjusting the noise. Strange. It came on again can't remember how but played for ages so it's sort of self fixed, so I plumbed it in a bit more semi permanent and even got away with the shite internal windscreen aerial, hmm maybe it was just a storage issue not being used for a while. Hmm will see....

 

Still need to rig up a permanent live from the battery to keep presets, and better speaker and cables, the standard sharp cable that came in the box look a bit rubbish, and the Old Audioline speakers could be better.

Try spraying any rotary controls with switch & contact cleaner, I've found that can really work. (maybe)
