It can be caused by many things such as cold solder joints, loose connections, failing components such as capacitors. Unplug it for about an hour tolet it reset itself to see if it will help, if not, you will have to open it and inpsect he inside, take the voltage reading before and after the problem.

My 3 year old Proscan 42" LCD TV picture suddenly


On the far left and right inside the back on panel are inverter boards. Replace or look for capacitors buldged, swollen, or cracked on their tops. Replace defective caps with original value and make sure replacements are 105 degree for longevity. Common problem, let me know if this helped.

"No Signal" Message when using HDMI Inputs on 26" Proscan LCD TV


You MUST get HDMI Driver for your Video Card, it is NOT standard. You need to go to PC makers web site and download latest Video Divers for your PC, then you must set up Multiple Desktops, To do that you must first connect the TV, but leave OFF, connect up to PC, reboot, setup Video Card, turn ON TV, TV will have already been detected, On PC, Share the desktop, or Clone, whatever you wish, now reboot after saving settings. Now you set the TV for HDMI already and it should show you a desktop when chosen. You must select and setup TV, FIRST, then connect the PC. From then on, Turn the TV ON, then turn the PC ON, that way it will Always detect the HDMI port.

Remote not working


If this TV came with an universal remote, try pressing the TV key. Sometimes it works.
If that did not work any other RCA, GE, Proscan universal should work.
