Double check the input, the simple way is using a good DVD player and good A/V Cable. plug in the A/V cable in DVD A/V output, then plug the other plug into TV A/V input. Then set your tv to AV input. if nothing comes out even though the dvd player is playing. The TV AV switch maybe damaged.

The remote control is an acess to the TV device for example only from a distance. A remote controll for functionality would require to insert batteries a power source making possible communiction with devices requiring reception transmittion of signals. The remote is handheld pointed to the direction of TV requiring signal before button pressed woudl achieve response. a common button to start the remote control experience is pressing on the power button, that displays a signal on the TV.

Faint lines show up when i get dark screens in movies


First check what color of faint lines comes then reduce Screen Volts in TV of that CRT (tube)
Take off lower front cover, speaker grille of TV, there you will see focus control block that has 6 control knobs, upper 3 knobs are focus adjustment of red-green-blue CRTs and lower 3 knobs are screen volt controls for red-green-blue CRTs. Turn screen volt control knob CCW to reduce screen volts of desired CRT.
Put TV on any free AV input so screen will be dark enough to adjust screen volts.
Thanks.

61md10 front panel controls lit uo, but the TV does not respond


With a non responsive remote that would be inpossiable you need to replace the control board inside around $100 bucks then you can have a good tv again but to get to the service menu your controll has to be working.

Screen is too blue


You will have to take the front cover off, usually 3-6 screws holding from the back, when it does come off there will be wires to the control panel attached still. you will also have another panel to undo. after that there will be a block with 3 focus controls and 3 screen controls marked b g and r for the three colors. The blue screen control is the one you are looking for, be very careful the slightesr turn has huge response including shuting the tv off when you turn it the wrong direction to far

Red CRT is dim....


Yes I did. You will need to get a service manual for this TV set to trace the voltage coming from the sweep power supply. If this is a problem that is new after you replaced the convergenbce4 board, you for sure have a broken wire or connection somewhere in the set. Have seen this happen may many times after a novice repairs a TV set. Good Luck
