Hi, welcome to Just answer
How old is Sony mhc ex66 ?
Purchased around 1997... ish
try to reset it
unplug the unit and plug it back in after 2-3 minutes...simultaneously press and hold the Function & Power button for around 20 seconds
let me know if it resets or gives a different error
The function button doesnt push in... the cd player still shows "REPAIR!"....
It appears that it has encountered a fault with a higher current drain which had triggered it to a protection fault condition. The fault can be with the mechanism (which moves the cd)...it seems that has gone bad and will need replacement...the cost of repair will be around £65
the fuse seems to be fine as it still shows an error
the unit is almost 16 years now...I recommend you can take it to a repair shop to get a estimate because it may just be cheaper to replace it....just my honest recommendation
I thought that might be the case..., many thanks
You're welcome....Excellent feedback is appreciated if you are satisfied with my assistance....Have a Good Evening
