Question about JVC RV-B90 Boombox
I bought my nb 90 off ebay and it seemed to work great until i turned it off. The stand by light stays on; however it will not power on again until i unplug the unit. This even happens if i try to turn it on with the remote. Could this possibly be caused by a fuse shortage of some fashion?

That problem is usually cause of faulty capacitors on the power supply board..
Just follow this instruction to fix your TV..
1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter
