ViewSonic VT2230 TV - Answered Questions & Fixed issues

I had the same problem. It appears to be due to a bad tv tuner. Turn on your computer and leave the coax unplugged. Leave it for a while (15-30 min). When you see "snow" on your screen, you will be able to use the source button to change to another input and see if you can get a signal. I am running my cable through a dvd recorder and using the AV input to watch tv. Also, my HDMI, component and RGB work fine. After thank don't try to access the TV source until you have had your tuner replaced.

Hi,
This kind of problem related to bad firmware saved in ROM that is part of main board so main board will be rpelaced to solve this issue.
It has nothing to do with power supply board that was replaced.
I'm not sure if main board is available some where as I could not locate it.
Thanks.

it could be your flux capacitor is out. you might need to plug it in goto menus and check to see if ur runnin 21 gigawatts if not leave it plugged in and off for two days and it should refresh it

Full instructions and codes here. For what it's worth, no one buys universal remotes these days, you buy a facsimile remote which is an exact copy for the television model you have. www.remotes.com. https://universalremote.codes/viewsonic-tv/ ..

Have a viewsonic n3246w but can't get it to tune in on dtv

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.

Some Viewsonic monitors have a Power Lock feature. However, these tend to be on the monitors (like the Viewsonic VA2265Smh) with only 5 control buttons. To toggle off the power lock, press and hold the button labeled 1 (Menu/Save/Exit) and the down arrow button for 10 seconds. The N2201W TV has more buttons than that. There is no Power Lock identified in my Viewsonic TV manuals. However, you might try the press and hold Menu/Down arrow combination. I hope this helps. Cindy Wells

To toggle the OSD lock off, press the Vol + and Vol - buttons on the Viewsonic N2011 simultaneously. This is shown in the manual on page 8, see https://www.manualslib.com/manual/306712/Viewsonic-N2011.html?page=8#manual . I believe these buttons are on the back of the unit on the right hand side as you face the TV. I hope this helps. Cindy Wells

Do a reset to this TV, and then check. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here.

Never forget to exit the service mode, after all adjustments have been done./

EXACT remotes are often VERY expensive... I would recommend a NEWER "Universal Remote" that will not only empower your TV, but enable you to use FEWER remotes! Here is a EIGHT FUNCTION REMOTE Starting at $7 from Target! GE Universal Remote Control 8 Device Fully Backlit DVR Functions Black Anthony

This sounds like a configuration issue to me, which your user manual should explain thoroughly. If not, Home Depot sells a small, cheap switch that you plug into your electrical outlet, and then plug your TV into that. I guarantee that if you get one, flipping the switch WILL turn the TV off. Maybe not as convenient as you might like, but highly effective.

Sounds like The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
