I have a Coolmax CATV converter on my old tv. It is less than 2 years old. It has always worked good. Last night I was trying to hit the LCR button on the remote while watching tv in the dark. Somehow I hit a combination of a few buttons and the converter box will now only let me view channels 2 thru 13. The box will only go up to channel 69 now (it's always went up to 102)by using the up and down buttons, but there is no picture for channels 14 thru 69. The box will not allow me to punch in 2 digit channel numbers from the remote. To the left of the channel number on the converter there is a u or v with channel numbers 2 -13. Somehow I have locked it up and I have tried everything from the manual for deleting channels from memory and favorites. Any suggestions? Is there any way to reset the box?
