 Unscrew the HTC and detach the pins. You may also have to unscrew the heatsink from the metal shroud. Then plug the new HTC back in and tighten all screws firmly. Unscrew the HTC and detach the pins. You may also have to unscrew the heatsink from the metal shroud.

If this doesn't help, try the other direction. Otherwise check the connections of the potentiometer. If you haven't simulated, that the display is floating (see Power Supply), this may be the reason. |
