VC500 - windows 7 - video shows up fine until "record" button is pressed. Then as soon as record button is pressed, I can't see video because of horizontal lines and bars. Video records fine, and can play it back on computer, but I want to see what I'm recording while it's recording. I have already installed the new "one touch video capture" software for Windows 7 to replace the "grabber" software that came with the unit. Same problem. Any help would be appreciated

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.

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.
