Sony Boombox repair no power

[@herby4215]

Sony products of this range are great

[@FrankJCarver]

Nice repair! Well done! One thing I hate about these boomboxes, is how close the record button is to the play. There have been many times that I have accidentally erased a favourite tape.

You will have to start breaking out the record tab on cassettes so it doesnt happen.

Thank you, mate!

love your work, im assuming you are based in Australia. Do you do work on laser disc players and dvdo units ?

[@StevesElectronicRepairShop]

Yes based in Australia. The only Laser Disc players I have ever seen were a couple I purchased second hand and resold sometime around they year 2002. They are rare in Australia. I have repaired DVD players but mostly under warranty, as they arent usually economical to repair given their low replacement price.

i had to clean my boombox and restore it as i got it from a garage sale and it had moths in it. after putting it back together it started overheating. I am 99% sure everything is in the right spot. Any suggestions?

[@StevesElectronicRepairShop]

Does it still work at all? What part is getting hot?

My Sony cfd-s22 won’t turn on, but I don’t want to mess with it a bummer

[@ParthChauhanMusic]

Hey, I am based out of India and here the power voltage is 220V. I plugged a Sony boombox from the US here without using a step-down adapter, and now it is busted, doesn't work. Do you know what part needs to be repaired specifically for this? Your help is appreciated.

If you are really lucky it might have just blown the fuse if it has one, or there could be a thermal fuse in the transformer. The wires going into the transformer will have two copper and two silver ones, the silver ones are the thermal fuse and can be bypassed if open circuit to test it. Just testing for resistance across the power cord pins will tell you if something is open circuit there. Sometimes though it will blow various things such as the amp IC, motor drive chips in the CD player and things like that due to roughly twice the normal voltage coming out of the transformer, and then the transformer may burn out as well.

@@StevesElectronicRepairShop thank you for such a detailed explanation. I will try to check this.

[@ParthChauhanMusic]

@@StevesElectronicRepairShop Thank you for your response. I will check once. Do you know if this model that you worked on in this video had a fuse?

[@StevesElectronicRepairShop]

@@ParthChauhanMusic I cant remember if it had a fuse, but most of them have at least the thermal fuse in the transformer to meet safety standards

​@@StevesElectronicRepairShop Same thing happened to my vintage JVC RC-X610. It was plugged in but not turned on and then I heard a sound similar to when you clap your hands, and now it doesn't turn on at all - CD, tapes, radio - all dead, worked perfectly before that though. Any ideas what that could be? 🤔
