I know we have alot of tech experts on these forums so I thought I'd ask for suggestions here.
I have a Memorex 32" LCD HDTV connected to my grandson's X-Box 360 and his computer.
His X-Box is set at 1081i using an HDMI cable to connect.
His computer is connected via a standard VGA cable with the resolution set at 1024 x 768.
When he plays games on his X-Box, after about an hour, the screen will go blank at random times. To fix it he has to bring up the TV menu, then close the menu, and the screen resets it seems. The game continues to play while it's blacked out.
This does not happen when he uses his computer.
I have tried keeping the TV hot with a blanket folded over the top, (as was suggested at the Memorex tech support site.)as well cool with a fan drawing the heat away and it continues to black out no matter what I do. I have also tried each screen resolution setting on the X-Box with the same results.
Any suggestions would be appreciated. I did purchase this TV as a close out model and all warranties have expired. It did not start doing this until recently, ie: the last few months.
