I bought a non working second-hand tcm-77v and I thought it would just be a regular fix, clean some contacts, change a belt. But when I turned it on everything seemed fine the screen lit up the buttons seemed to be working and displaying on screen the options but then when I put the tape in the whole screen glitches for a moment fading in and out and the number on the tape counter goes up until like three hundred and then it's bricked until I remove the battery. When I press play with no tape the screen shows the signal to put a tape in. Can anyone help?
Ok, update the problem only happens when the tab 2 is pushed. I don't really know what to do with this information, thanks in advance,
