Question about Televison & Video

6 Answers

I have a problem with a double DIN 7" Touch Screen in car audio/DVD/GPS/Bluetooth/MP3. Car battery went flat whilst parked(due to Parking Lights left on)and had to be push started. When clutch started, touch screen went blank(although sound was still evident. I have not been able to obtain any improvement in this condition. Power button works and is illuminated. All function buttons illuminate when unit is turned on. Screen Tilt function operates as intended. No sign of life on screen. Any ideas would be helpful. This unit is a Chinese manufactured item that was working perfectly for the past six months.

    Unit has been removed from the car for several days, checked for visual signs of damaged components, and replaced in vehicle. No sign of screen coming to life when plugged into wiring and switched on, however Automatic Radio Antenna extends when Power button is activated.
    Any more ideas?

    Further trial and error testing reveals that the Radio,DVD,CD,and
    possibly GPS touch screen buttons and sound are all functioning, but
    not visible on black screen. This would seem to indicate that there is
    some malfunction of the video output.
    Ideas please.

    There isn't one solitary name or Model No. to be found any where on this unit(except some circuit board Part No.s). Unit is NOT factory fitted, it is an aftermarket item. Would these pico fuses be easy to identify and/or test?

    Very helpful thanks.

Hi

You didn't happen to get any make and model numbers of the unit whilst you had it out. Certainly sounds like the unit has a logic lockup caused by the battery going dead flat. I don't suspect the subsequent clutch start has affected it, more the brown out effect of the dead battery, or same when trying to initially start the car. It is possible that is has blown one of those pesky circuit protector pico fuses internally in the power supply switching stages. They can be problematic with interrupted voltage problems. If you can give me more info on the unit, I may be able to get a better diagnosis or a reset procedure for you. I take it you have inspected the front panel for any small holes that may have a reset switch behind it. If it is a factory fitter, there may be something in the user manual about doing a reset.

regards

    They come in many shapes and sizes, and can be surface mount devices(no leads soldered straight to the board, small 2 pin black plastic device that resembles a transistor in shape. They can be as low in value as a few milliamps,and are designed to protect circuit stages if a problem occurs and can be numerous and plentiful through out the unit, A good bench technician that is familiar with car HiFi/electronics should be able spot them and diagnose the problem for you.



    You say the screen is black, but is it actually blank. Can you see anything on the screen when you shine a torch up to it. It may be a backlit screen that the power supply stage has failed to.



    The lack of brand names on the equipment points to it being a "back door" end of production run product. It may well be a decent brand that was bypassed off the production line before branding. A not uncommon move for smart importers and sneaky manufacturers. If there are any numbers anywhere... :) then we may be able to track down the donor brand of the gear and assist with some more info.

Hi, I had a problem something similar to this. But it worked fine after sometime when my car was running.
The problem was that the battery was weak / not getting charged properly. Once when I fixed it everything went fine...
Sometimes the solution may be simple... Check the battery once please ...
Thanks, :)

Hi,

If this had been jump started from another car battery to battery or put on a battery charger without removing the fuse to the player I'd say it was suffering from an over voltage surge. I don't think that can happen from a push start, but it is possible. But, what can happen form a jump start is a loosened connection to the video screen dislodging.

This connection needs to be checked for breakage and not just looseness leading to a disconnect. The connection should be BNC to prevent this by design, but that doesn't mean it was and is. Unless over course this has been checked and you didn't say so.

OK?

    So, the unit was in the on position when the car was jump started?

    There still may have been a voltage overload from the jump start, although I think this is far fetched personally.

    As you now state, the unit was removed for component problems and reassembled and inserted. This precludes problems that I had suggested with a connector (a rather obvious conclusion you also considered already). As this problem may still be a result of it being in the on position while jump started by motion and a clutched popped, I'm going to defer further troubleshooting to an automobile troubleshooter who is up to code on current technology. My knowledge ends with the early 90s when I left cars for computer assisted devices.

    Sorry I can't be of any further assistance.

    There is no need to rate this solution, although a Helpful would be nice. As you refuse and move on to the next (you actually do not need to repost every time, you can add information, but you don't have to restate it, we can see it all) the system gives an automatic Thanks for Trying. A Helpful from you will not obligate you to any payments until you hear from one of our car geniuses here at FixYa. We have many. You'll know one when you hear from them. The one that comes to my mind is Toyota Ed. He is amazing.

    Best Regards and good luck,

you can not play dvd's when the car is not in park with the e brake on.

I grounded my Jensen to a screw inside the dash. I had to put a switch on it though - Jensen requires an on-off-on sequence with the parking brake, which applies and removes the ground. I duplicate this by throwing the switch. Check the manual or online references to see if you have to do this. If you do, you'll need a switch. If not, you can just ground the wire.
