    Its a Vision Plus / Nikkia (10.4inch from Maplins) DVB/ATV/VGA etc ... Model No.JV-TV104A several of the boards inside have 104---- as a reference.



    I have now progressed to a white screen no sound or menu etc just bright white screen, no standby light during its "off" setting either.

    I am sorry. I cannot find any information on your TV whatsoever, other than its a digital TV. It sounds like a video transistor or a solder joint. Look inside and try to find some numbers stamped on a 4 or 6 legged IC mounted to a heat sink and I will cross reference them to see which ones are video ICs. thats about the only option left due to not having any service info for that model hope this helps.

My old tv has its own power switch on the set can I buy a new set with this type of function?


all tv's have their own power switch, but most are electronic in that it relies on a pulse from that switch to the microprocessor to turn set on or off.

Power up problems


It sounds like the power is pulsing - that would explain your speakers. Speakers wouldn't make that sound if they were getting power at a steady rate. Look for a bad capacitor. It's possible you have one or more capacitors that have gone bad. They charge to a certain point, then somehow complete a circut momentarily and discharge, giving a pulsing flow of electricity. You can look for visible signs (leaking capacitors, or capacitors that are leaning over), or you can just start testing them with a voltmeter. If you find a bad one, you'll have to get a replacement and solder it in place.

LG 17LX1R flashing red LED - TV won't power up


Try changing the input device to something you are sure, works such as a DVD player.

Switch off TV manually, switch off power, remove plug and retry after 48 hours.

If problem persists, please refer it to a qualified service technician.

The panic alarm sounds


it sounds like one of your door switches is setting off the alarm. Or you hood or trunk switches.

Anti-Theft -Perimeter The perimeter anti-theft system consists of the following:
  • door lock cylinder disarm switches
  • liftgate lock cylinder disarm switch
  • generic electronic module (GEM)
  • door open warning lamp switch
  • pulse stretcher module (wagon only, is located between the rear license plate housing and bracket)
  • keyless entry remote transmitter
  • hood switch/bracket assembly
-----------------------------------------------------------------------------------------------------------------------
Principles of Operation
Perimeter Anti-theft
The perimeter anti-theft feature provides an audible and visual alarm when unauthorized access to the vehicle is detected. When an intrusion is detected by any door or liftgate ajar switches, or the hood and trunk tamper switches it sends a ground signal to the GEM. When the GEM receives a signal indicating intrusion into the vehicle, the GEM supplies a ground signal to the horn control relay and the park lamps relay. The relay closes, supplying the power which activates the horn and the park lamps. The pulse stretcher module applies to wagons only. Due to the distance between the liftgate disarm switch and the GEM, the disarm switch signal is not present long enough for the GEM to recognize. The pulse stretcher module receives pulse input when switch is turned to unlock. The pulse stretcher module holds the pulse active for about 60ms so the GEM can recognize the signal and disarm the system. The perimeter anti-theft feature does not arm until 20 seconds elapses after locking the vehicle. The perimeter anti-theft device will disarm only when
  • unlock is pressed on the keyless entry remote transmitter.
  • keyless entry keypad code is entered.
  • door, luggage compartment lid or liftgate lock cylinder is turned to unlock.
  • ignition switch position changes to run or start.
Inspection and Verification
  1. Verify the customer concern by operating the system.
  1. Visually inspect for obvious signs of mechanical and electrical damage.

  • Lock cylinder disarm switches
  • Hood switch
  • Luggage compartment lid switch
  • Loose or corroded connections

    1. Remove the E-clip.
    1. Disconnect the latch lever.
  1. NOTE: The door disarm switch can be installed in more than one position. Before removing the switch from the cylinder it may be necessary to mark the position of the switch in relation to the lock cylinder.
    Remove the door disarm switch.
    • Disconnect disarm switch electrical connector.
  1. NOTE: The door disarm switch can be installed in more than one position. Use the reference marks applied in the removal procedure to index the new door disarm switch to the lock cylinder.

Picture pulsing, tv turns off and on


Sounds like a power supply problem, If you are competent with electronics, you may find some blown capacitors or resistors on the power supply board. Equally you can probably buy a new power supply board.

WARNING: the power supply board contains lethal voltages even when switched off and unplugged. If you are unsure what you are doing take it to a repair shop.

No power to fuel pump no hum when key on and inj not pulsing


Fuel Pump Relay Circuit...
There is an Oil pressure switch in this circuit that disallows the relay to complete the power supply to the fuel pump. It is for safety purposes , it senses engine oil pressure upon cranking of the engine and then completes the ground circuit to close the relay sending voltage to the fuel pump at start up, and also functions as an engine kill if you loose oil pressure opening the ground circuit which in turn opens the contacts in the relay shutting off the power to the fuel pump.... Invest in a vehicle specific repair manual with wire diagrams... hope this helps..

VTech 5.8 mhz won't work


I found a solution that fixed this problem (at least for me). On the vtech site they said to unplug the base unit for at least 5 minutes. Previously, I had only unplugged the base unit for a few seconds. This time, I left it unplugged for about 10 minutes or so and when I plugged it back in, everything was working fine. Apparently there is some sort of capacitor that must discharge long enough to completely remove power from the circuitry.

Good luck and I hope this works for you!
