Sharp CD-C3800 won't turn on

How about when the radio is on & the key is off or
in your hand,if you open either front door does the radio go off
& do you lose the delayed window feature assuming you have that
If so you problem is a delayed accy relay
Next would be the front door switches
I will give you credit for what you tried
but fail to see why you would switch motor
from door to door,they work powered directly or they don't
I would think your battery would have gone dead by now
if the relay failed to time out or go to sleep

I have seen the current gas eat away and melt fuel lines. I would bet there is some gunk in the carb which is why you are not seeing fuel on the plug. You will need to remove, disassemble, and clean the carb. If you haven't done it already make sure you replace the fuel filter too.

Could be a few things.1.) Have you ran a firmware update lately? If so, I'd suggest reverting to factory settings.2.) If you haven't updated, it sounds like it's internal. Could be faulty hardware (4 years is quite awhile). Contact nintendo.

Hi Kolya, Check around for a loose or broken cable especially around the battery connections. Regards John

Try returning it back to Walmart, the camera maybe covered by warranty, otherwise it won't be worth fixing as it may cost more than $20.

Hello!
If you have used your TV 24/7 for the past year, the issue might be in the power supply. If there are "bloated" capacitors, set will not start up. If you haven't unplug it for a year, it might be staying alive. Once you unplugged the set, those capacitors won't let your set back to normal. That's a big project and requires technical background. If you think you can handle that, open your TV set and inspect TV's power supply board. It will be located near power cord plug or wire. Also, it might be covered by tin shield, which must be removed for further observation. If you see any "bloated" electrolytic capacitors, replace them with same value and voltage. But it might be main board's issue, as well. what is your place's ambient temperature? If it's lower, than 75F, try to warm up the back of the set, before even trying to poke it open. Use hair dryer. First, point it on main board's in/out connectors. Do not overheat! Few minutes might be enough. Then, try to plug the set in and observe the behavior. Any change? turns on? Main board is bad. Same with power supply. If heating up main board area does nothing, try power supply area. If it makes a difference, start looking for bad capacitors.
Good luck,
Let me know results.
Thanks,
Alex.

the only thing you can try to do: unplug TV, let it "reset" for a minute or so, then plug it back in. If that won't help, means: surrender to repair service. for 1 year, even with 24/7 usage, there is a slim chance for "bloated" capacitors inside of TV's power supply, but quite a good chance of your main board failure. Now a days they quite compact, packed with high temperature producing IC chips, led-free solder, which has drawback of "fatigue" failure. Or, there might be power surge involved. In any case, except "lock up", appeal to TV repair service.
good luck,

If you already have your dash apart, have you looked for a fuse directly on the radio itself? There should be one somewhere near the power wiring on the back of it. If this is blown, you will be getting power to the wiring, but not to the radio. Replacing this fuse should help you out.
If this is not the problem, use a voltmeter to check the wiring where it goes into your stereo. If there is no power here, then the power overload that blew your 10amp fuse is probably related to a short circuit somewhere in the wiring between the fuse and the stereo. To repair this, you will likely have to run a few new power wires (you should replace both the positive and negative to make sure you have fully bypassed the problem) from the fuse to the stereo. If you have checked these wires with a voltmeter and they have power at the back of the stereo, but the stereo itself is not still not working, then the problem is with the stereo itself.
If you find that the wiring to the stereo all has power ... the fuses are all good (which you have already stated) ... the fuse on the stereo itself is in good shape ... then there might be a short within the workings of the stereo itself. If you are not experienced with repairing electronics this could be out of your ability to fix -- you can bring it to a shop or buy a replacement. If you are experienced with repairing electronics, open up the stereo and start checking the wiring (starting from the closest point to the power input and moving towards the stereo's face. This could be a long and arduous process ... so if you are not experienced with it ... I recommend taking it to a professional or just replacing it (your hair is probably worth more than the $100 you would spend on a decent replacement stereo ... and if you are like me, you would be ripping out your hair after checking the first few hundred possible connections within the stereo itself).
Hopefully it is just the fuse on the back of the stereo itself, and you can have that fixed in short order. Good luck!

You must 'reset' the remote. I've had it happen quite a few times.
1. Turn off power to fan. Then back on.
2. Using remote cycle the following fan buttons from high to med to low, then from low to med to high again. That 'should' fix the problem.

Hi, That`s an easy one, you have a bunch of broken solder joints on the sweep board, if you are proficient at soldering you can fix this yourself, if you are NOT then call a tech out, this is a cheap, quick repair, get it done and start enjoying your set again, hope this helps, Happy Holidays.
