I am getting a "no signal" on the blue screen on DTV mode of my Protron PLTV-3750 LCD. It has worked until I moved it to a different room. The signal is good on other tv. Anything I can do?

First make sure you have your cables connected securely, then try to move your antenna around and rescan your channels everytime you move the antenna.

Power supply 3750 protron

These cicrcuits boards are no longer being manufactured. The only option at this point is to get the defective power supply repair but most service techs do not want to fix them.
I can repair it for you but you will need to remove it and send it to me.

Using protron as a monitor with mac

Need to set resolution and refresh rate on the Mac before plugging in to the TV set - had this same problem with a WinVista machine. According to the documentation, the only supported resolutions are:

640x480 60Hz
800x600 56Hz
800x600 60Hz
1024x768 60Hz
1280x1024 60Hz
1280x768 60Hz
1366x768 60Hz

In all fairness, I cannot get the unit to run in 1366x768, though - get out of range. 1360x768 seems to work OK though. Only real problem with the VGA input is that regular text mode on a video card (more of an issue on Windows machines) does not work.
