Question about ViewSonic N3752w 37 in. LCD TV

Open Question

How to repair my viewsonic N3752W. It has limited response from the remote and no use of the manual controls.

I have a viewsonic lcd tv that was zapped with static electricity while turning it off manually. It will now only turn off or on with a remote. I can use it as a monitor with hdmi, and pc mode.

Yeah, my 19 year old daughter did the same thing. I found a solution on the 2750W thread

Solution - just press Menu, Enter and Power buttons at once.

SOURCE: TV wont turn on with remote or the power button

ONE: The protection circuit has taken over the power managment of the set. When you unplug it for a couple of hours or so and plug it back in it will start up because the circuits have all been reset (unplugging the power cord is a reset operation.)

TWO: The protection circuit goes into action whenever it detects an excessive amount of current being drawn from one of the 10 sections of the tv circuitry.

THREE: When it won't turn on it is because the protection circuit has captured the ON function and holds the power relay OFF until it is reset.

FOUR: So, the problem area could be any one of the 10 or so sections of the tv. The most common of which is the high voltage section because it uses the greatest amount of power. If so, this could be very expensive.

FIVE: On the other hand, it could be one of the other sections and a small part such as a resistor or capacitor shorting down. In which case the cost of repair may be only a few dollars.

SIX: However, you will need a tv tech to come to the home and diagnose the set because we cannot tell where the failure is without a hands-on diagnosis by one who knows how to test the circuit sections.

SEVEN: Usually a shop will send out a tech who will do a quick check and tell you what is wrong with the set and how much the repair cost is going to be. A house call such as this will cost from $40 to $80 depending on the distance and the price they set. I suggest you call a few shops and get their best response before deciding which one to employ.

Let me know if you will need further assistance

What is the code to use on a universal remote


Each brand of universal remote could have it's own code for the TV so without more info, no one can help you.
You can also check to see if you have a search feature on the remote which will allow you to try every code until one works.

You may have bad main logic board, http://www.shopjimmy.com/catalogsearch/result/?q=n3752

The back light is working for sure, you may want to check if the Power supply on signal goes to 5v when you push the power button.

It sounds like the LCD panel is badly damaged, if that is the case, it will not be worth it, sceen is the most expensive part of the whole TV, you may be able to sell each parts of the TV on EBAY. Post the pictures of the screen will help.
