40H80 Problem TV will not switch to non antenna inputs
My toshiba 40h80 projection will not switch from the antenna input to the video 1 or video2 inputs. When selected the TV just flickers and stays with the same inputs. Both coax antenna inputs seem to work fine. It is only the other inputs which I have a problem with.
Anyone have a similar experience? Or an easy fix?

Sounds like you have a bad tuner. It is not uncommon for solder joints to deteriorate over a period of time and loose continuity. If you are handy with a soldering iron, you can try to fix it yourself but I really recommend leaving it to a professional.

Ur convergence is dead.U must know how to solders?Must replaced 2 STK convergence ICS and some or all it resistors.Tries Websites Tv repair World.com,Tvrepairkits.com to buy a convergence kit to repair it ur self.The shop will cost U $300 for parts and labors.
The only thing you can do is to unplug the tv for 30 min. Then turn it back on and see if that fixed it. If not call a repair man, you are most likely missing a power supply voltage or deflection voltage.
try to replace all the 10mf16v surface mount caps in the next-hyper unit. it is the digital scan card which is why you could get the higher res output devices to work. you can replace them with regular electrolytic caps if you cut the legs short enough. i would recommend using 2 soldering irons to heat both sides of the surface mounted cap at the same time then let gently pull the cap off.
******make sure you check the polarity of all the caps after you are finished****
