jvc does not sell it. so only used parts now. ask them ?
and using ebay ,you might get lucky
it is not a computer. (it's a BOOM box stereo noise maker)
JVC re-invents portable stereos with the RV-B90GY Kaboom. It's the highest power portable
stereo ever offered;
or goggle the while earth for it.
battery cover
JVC RV-B90GY
we sell no parts here, all we can do is point to the obvious.
inside there must be a transformer for the ac and i would assume that it works fine but that a component on the circuit board that runs both AC and DC has failed. look for 4 diodes or a 4 legged voltage rectifier and or a resistor after it. Look for burned circuit traces on the under side of the board.
Could be a blown fuse... it's located behind the right end woofer when looking at the unit face. Remove the round plastic molding and then remove the actual woofer. You will then have sight of the fuse... it's really hard to reach, will need something like long tweezers to reach in, grab and remove. Replacing is also challenging but you will figure it out (1x 250v 1.25A glass tube fuse)
Perform a manual power reset by following the steps:
1. Turn off the camcorder. 2. Disconnect AC power adapter. 3. Remove the battery pack. 4. Move the POWER switch to the A position for 15 seconds. 5. Move the POWER switch to the OFF position. 6. Reconnect the AC power adapter or reinsert the battery pack. 7. Turn on the camcorder.
whenever I run into a memory issue with a portible unit that uses a battery backup I have found battery corrotion on the battery cointacts! also remove the main power source the batteries the wall plug and let it set for several minutes and hit the power switch a few times then retry everything again

It is not much difficult.Look for AC supply cord. Test it on Ohm meter and then look for AC voltage.Look for continuty of mains transformer,look for DC voltage, 12 volts and 5 volts if both the voltages are present then set should work.
