My problem: LCD display gives out light, but no picture. Presumably moisture has been drawn in. Remote control can be operated blindly.
ATTENTION: four contacts have to be desoldered when replacing. Even with a solder remover it was not possible to pull out the display after removing the solder! The contacts had to be pinched off and drilled out with a 1 mm drill. Extreme caution is required!
After installing and soldering the new display, everything worked perfectly again! :)
