Verify that the set is set for the correct input by pressing the source button on the remote to check if the cable is selected as the input. If not use the arrow keys to select the proper one and press OK

Setup proscan tv


Newer tvs have a lot of input connections ( holes) and can be very confusing. With out knowing what kind of plugs you have I will try to help as best I can. First ,if you have a coax cable hook it to the corresponding connector. The coax is a pencil sized cable that has a center wire and a threaded nut. It will screw onto the threaded connector on the back of the tv. If you have RCA cables these will be color coded yellow for video red and white for audio plug these into the corresponding connectors. There may be more than one set of these connectors and may be marked input1 or input2 etc.make sure to write down which input you plug these into.you may also have colorstream cables there are three green red and blue. Some of the newer tvs don't have inputs for these but if yours does plug them into the corresponding colors. Another cable you may have is a s-video cable this is a single cable that has a multi pin connector on each end. Again find the corresponding connector and plug this cable in. The newer cable is called a hdmi cable and is a cable with a rectangular end. This one cable takes the place of the multi-pin s- video cable or the RCA cables. It also replaces the colorstream cables. If you were able to connect all your cables up. Turn on the tv. You may get a blue screen that says no signal. Don't panic take the remote and find the input button. Pressing the input button changes the tv to the various sets of inputs on the back on the tv. Press the input button several times waiting in between each press of the button for several seconds untill you find the input you connected your cables to. If your connecting a vcr make sure you have a video playing so there will be a signal for the tv to find. I'm not sure what a PVR is, but make sure it is playing some thing when you scroll through the inputs on the tv with the remote. Hope this helps.

Vertical blue line has appeared in the middle of the screen


Hi, is the blue line from top to bottom or from left to right?
is it on all inputs all the time, or just one input sometimes?
if its there all the time all inputs sounds like a bad panel, probably damage to the tiny ribbon cable on the edge of the screen, probably not user fixable, Viewsonic does warranty there monitors for 3 years by serial # though worth a phone call. good luck

My cable box is hooked up to the HDMI input on the TV. The signal is going out for a second fairly often. The screen goes blue and says no input.


A weak or interrupted cable signal will cause digital dropout. Have your cable company increase the cable signal level to your box from their main office. They may have to send a technician out to measure the signal level to see if it is a problem.

Tv has no reception.


Make sure you have a signal to the tv, dvd player, cable or game console.
Press the input button on the remote or the control panel on the tv.
You may have to press it several times until you get a signal. Let me know if this helps and please rate this solution.  Lone99star

Screen remains blue with "no signal" written on it, inspite of a cable connection and, of course, the input set to cable


Probably a bad video processor board

But, 1st try using a different type of Cable such as IRC, STD, or HRC different freqs and channels

Also, try using a vcr or dvd on one of the inputs to see if that works

Can't pick up all the signals


I always tell people to carefuly read their instruction manual and consult the product tech support before determing that there is actualy a fault with their unit.

If sounds like the tuner module or the controler board for the tuner may be failing, or there is a power supply distribution fault to the tuner section and or its controler. This has to be service by the manufacture.

One of the criteria I recommend when people buy an expensive appliance or TV is to make sure that there is local authorized service. I also recommend an extended warrany for expensive items. The warranty is like insurance. You may or may not need to collect!

TV Picture cuts off.


The blue screen means that you have lost signal. If the set don't have signal for so long it turns itself off. "power saver feature" Check all connections or replace cables, If that don't work the signal board may be going bad.
