You can open it when remove all screws at the back, from the stand also (under the TV).
Then carefully remove the snap-in shell ( front and back). TV is one compact part and plastic shell is snapping ( front and back) + stand, on the screws.
Picture goes out after 1 second, audio is fine
the problem is not the mian board but the DC to DC inverters that drive the lamps behind the panels some manufactures make them available seperate from the panel but most are a part of the panel. so the whole panel may have to be replaced.

You could order a power supply yourself and install it, but if the tech
on the phone was wrong it would cost you a lot. Better to at
least inspect it yourself.
If you are not familiar with electronics it could be tough to pin down
the fault. Over-the-phone diagnoses are really only 50"50.
It COULD be any of the following:
Power Board
Main Board
Control Board
Control Board Wiring Harness
IR Receiver Board and or harness.
Visually inspect the power board for any capacitors that are vented or
have shrunk cases on them. Check it for brown spots on the board
itself. If there are brown spots you may have an overheating component.
If it's s discrete component like a resistoror diode you can replace
it. If it's an IC, you may have trouble finding it and might end up
replacing the whole supply.
On the main board you can check all the connectors to make sure they
are plugged in all the way. Make sure there are no overheating
components.
On either of these boards, if you find dark brown spots you might want to consider replacing that board.
You can replace any bad capacitors you find easy enough.
Our shop would charge $75 labour and the cost of the part for a repair
like this. A few hundred dollars for a circuit board is not unusual.

Connecting a FLat Panel TV to me PC
Check your owners manual.
You need either a 15 pin VGA cable or a DVI (Digital Video In) cable.
Look at the back. If you have a small D-Type connector with 3 rows of 5 holes you need the VGA cable.
Of you have a rectangular connector with rows of angular holes and two slotted holes on one side then you need a DVI connector.
If you're current monitor cable is removable from your monitor you can likely use it.

Greenish tint
First of all component inputs are analog as the only digital inputs are the DVI or HDMI inputs on a TV. You might have color adjutments in the menus somewhere that allow you to compensate for color weakness on one or more colors. If not you most likely have a bad digital board.

on the bottom of the monitor there is a audio input. you must connect you pc output(green) to the monitor input with a male to male audio cord.
you can also use a rca cord with two adapters.

First make sure that the current input Source is set to TV to see the option for scanning for channels. There is a Source button on the front of the TV. (It's on the right side as you look at the front of the TV.) The Source button on the original remote is on the left side below the number keys.There are two RF (coaxial) cable inputs near the VGA port on the back of the TV. The digital RF signal needs to go to the port above the VGA port.
To scan for analog channels, press the Menu button. Then navigate to the TV setup option with the Up/Down arrows. Press OK to enter the menu. You can use either the Auto search or the Manual search. However, the Auto will be faster. You can set your country or leave it to Auto. Navigate to Start and press OK for the Auto-scan. There is a DTV menu button above the Volume + button on the remote. Use this menu and look for the Installation section to scan for channels. Again there is an Auto or Manual option.
ManualsLib has the manual for the Viewsonic N3246W here:
https://www.manualslib.com/manual/306714/Viewsonic-N3246w.html. See page 23 for the start of the analog TV channel scan information. See page 30 for the digital TV scan.
I hope this helps.

(For any channel provided by a set-top box, you will not be able to use the TV to store the channel lists.)
