Seeking a 12V plug for the JVC RV- NB90 , who knows what plug you have to use it?

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.

1. google
2. ebay
3. ask maker.

need to notify the camper manufacturer or an rv shop because most camper / rv are not cookie cutter designs -[ multi options ]

sounds like a dry joint in the power supply wiring inside,probably the printed circuit.easy to fix for an radio shop

hi i know it a bit late but wated you to know. to find service manual(has schamatics) google your model (JVC RV-B70 service manual) dont pay for one as i found on for free on hifimanuals.com i think. google is your friend. good luck

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

Sounds like the Fuse on the power supply board. Gonna do an R&R
of my fuse in a few days.I purchased the .PDF service manual for about ten bucks.

tune into the station you want as normal. Then on the remote, press & hold the number key for the preset number you want. This will flash in the display to show you it's set. You can preset 30 FM & 15 AM stations.

This is the backlight, bulb 9V. must be repaced, i suggest to replace by a 12V. bulb
Unit has to be disassembly. Good luck
