Veon tv manual

The eject button on the remote appears as an upward-pointing arrow with an underline - see below image. The eject button on the TV has a similar symbol.


However, I suspect that in your case, you might not be having a Remote.

This link says that your TV doesn't come with a Remote and DVD cannot be ejected without the remote :

Power supply problem no switching

( "Power Supply Problem Not Switching "???? )

How do you know it's Not Switching? Do you mean the TV wont turn on when you push the power button on and off on the TV and also with the remote control unit? Is that what you mean? If YES! Then, If your Vizio TV wont turn on and has NO-PICTURE, NO-SOUND and a BLACK SCREEN, Then the TV has an AC or a DC Voltage Problem.

1 - First, check the wall outlet socket by pluging in a lamp to see if you have 110 AC-volts there. If the lamp works, the wall outlet is OK! That means the problem is inside the TV.

2 - Before, you remove the back off the TV. I want to *(CAUTION - YOU)* The Power Voltages inside your TV are Very, DANGEROUS!!! There is 110 AC Volts at a 20-AMP-Rating ***CAN BE A LETHEL DEADLY SHOCK HAZARD to HUMANS!!!*** Also there are DC Voltages ranging from 3.3 to 24 volts. And R-F- VERY-HIGH-VOLTAGE of 20,000 Volts or More.

3 - You will need hand tools and a Digitle Volt Ohm Meter to check AC & DC Voltages and the OHMS Meter section to check resistors, capacitors, coils, grounds and contacts.

4 - With the Back removed, and no-power to the set. Inspect the power board for any signs of BURNED, LOOSE or BROCKEN parts like resistors, capacitors, coils, fuses on all boards. If you discover damaged parts, make a list of them. Then you must deside if you are qualified to do the on board repair or just order a new replacment board.

5 - If on the other hand you didn't discover any damaged parts by your inspection, It's time to put the Meter to good use. Plug the TV power cord to the wall outlet. Set the Meter for AC - voltage range of 200 or more. check for 110 AC volts going to the power supply board fused inputs.
If NO replace the cord. If YES, look on the board for voltage test points marked on the board. (SAMPLE!) 3.3 vdc, 5 vdc, 12 vdc, 24 vdc, and so on. Set Meter for DC Volts now, range 50 to 100. Put the black lead to ground and the RED lead to each test point marked on the board while repetetedly pressing the TV power on & off button..

6 - If ANY of the DC voltages were LOW, WRONG or MISSING, The Main power board is defective and needs to be removed and replaced with a new one. Write down the board number that is on the board and use that number to order the new one. You can order it on the Net!

*****(NOTE)***** If you are not an electronics tech. don't try to fix the old defective board... but, keep it handy, you might need it for parts later. :-)

Hope This helped... GOOD LUCK! NOW, GO FIX YOUR TV!

How to use

Voltage testers and volt meters are two different things. A meter will provide a an indication of the exact voltage and type AC or DC. A tester on the other hand simply provides an indication of presence of power with little to no indication of how much or type.

AC power is what is provided by most power companies in the world. DC is a type of power provided by batteries and DC power supplies. If your tester or meter has provisions to check for AC and DC, you should check for BOTH. If AC power is present and you are have set your meter to test for DC power, your meter will indicate 0 volts. You can see this can be a dangerous condition. Most simple testers will not care if AC or DC power is being tested and the types that use neon lamps will usually glow differently for AC and DC power.

When setting up for testing voltage, you must test across the power source (or in "parallel") or load (such as a light bulb), as opposed to "in series" with the power source. Across would be from the + to - post of a battery, into the slots of an outlet, etc. "In series" is when the tester would be completing a circuit - such as testing across an open switch.

First, check the meter's operation by testing a known good power source by following the next steps. Set the meter for the type power to be tested. Choose AC if unsure. Next, set the meter for the highest voltage range supported. Make sure this range is higher than the expected voltage, otherwise damage to the meter may result. Connect the probes to the power source. Read the meter. If the meter moved only slightly, adjust the range of the meter to the next lower value. You can keep adjusting downward as needed to get the most precise reading possible - but do not set the range to a value less than the voltage present. A 0-300 volt scale is the lowest to measure a 240 volt outlet - switching to a 0 - 150 volt scale will damage the meter. The 0 - 150 volt scale would be fine for measuring 120 volt outlets.

If the meter did not move, change the type from AC to DC. and repeat. If it still does not work, the meter is not working correctly (if testing a know good source) or there is no power present (if the meter worked on a known good power source).

Good luck!

The batteries is charged but won't start

This can be complicated. You must have, on most power chairs, at least 22 volts DC to turn and 24 to 26 volts to drive. Check voltage to power module and joystick. Check fuses in battery wiring harness.

I have a 50 inch lcd tv,the sound works but no picture. What could be the problem?

your problem is in the video section check your video ic 201 the number 1 pin should be getting 5 volts dc input if the voltage is absent then checkQ 210 it could be bad replace it.if the 5 volts is present check the ic output for 125 volts dc if absent replace ic.good luck.

For use during an extended power outage, where of course you wouldn't be able to recharge the battery after it drained initially, I'm wondering if anyone has tried using a 12 volt lead acid rechargeable...

You simply need a DC - AC Inverter, these can be obtained from somewhere like Radio Shack, or the like, pretty cheaply. These convert 12V DC into 115/120V AC (Some are 24V - 115/120 V) for use with your household appliances. You can get them from 100 Watts to over 1 kilowatt (!000 Watts) They can be used on almost anything at all, except things with big motors in them. Then you can simply plug the AC adapter into the inverter and you are good to go. not having to worry if your laptop is getting correct power.
Often the DC input into a laptop is between 14 Volts DC to 22 Volts DC and a high current too, up to 5 Amps. So the inverter is your best option.
Anyway you would need to use at least TWO 12 Volt batteries and then you would have to make it the exact voltage the laptop needed.. if it was say 19V then you are still going to have to find a way to drop the 24 V to 19 V, anyway so.....
