Question about JVC RV-B90 Boombox

1 Answer

NB 90 will not power on after turning off unless i unplug it.

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?

Good day!!!!

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

I just purchased a toshiba mini notebook NB 505 it has about 5 hrs. of time on it. Went to turn it on the other night and when it starts up the screen was lite up but nothing else. I can not shut down...

It happens when the NB was not properly shutdown, NB was turned off due to battery drained and left idle or worst there is a problem with the mother board. You may try this; Turn OFF the laptop, remove the power sources (ac adapter and battery). Without power sources, hold power button 10 secs. Put back the power sources, and power ON the NB. If the laptop will not boot by doing this, take it back from the reseller for replacement.

What exactly does the anl nb/anl button do on my cobra 29 wx nw st

ANL stands for "Automatic Noise Limiter" and NB stands for "Noise Blanker".

The ANL gets rid of a lot of interference noise caused by mechanical noise from motors and other electronic components in a car.

It also gets rid of noise from other sources of interference.

The NB is for extreme cases of noise, but can slightly lessen your receive sensitivity.

Basically both functions help decrease interference noise.

My Acer Extensa 5420-5687 laptop did not boot already..if i turn on the power button it will turn on but after a few seconds it will turn off automatically. What is the problem of that? I hope that i can...

First thing is make sure the Notebook is not Overheating if, the NB is hot turn it off until the unit is back to normal room temperature and the check if the fan of the NB is functioning and make sure your using it on a flat surface and if the NB is overheating or the fan is not working then BIOS update will help resolving the issue

if the issue is not due to overheating or above steps does not help to resolve the issue then Boot the NB to BIOS then check if the NB turn off Automatically in BIOS screen as well then if it does then its a Hardware issue you should contact the manufacturer

Note: while doing the above steps make sure the ac Adapter is connected to the NB

My hp pavillion was no power, please give an advise.

There could be a problem with the battery. A fast check to determine whether you have a problem with the power adapter, power cord or the laptop's battery is to turn off the laptop, remove the battery, connect the power adapter, turn on the laptop & see if it works.
If the laptop works directly from the power adapter with the battery removed, then the power adapter is good. In this case we can suspect that the battery is defective & needs to be replaced.
To verify this, unplug your laptop & try to run it on battery only. Watch out how long it will stay on (if at all). If it didn't work on battery alone, or worked but for a very short time, then your battery is defective.
