In reply to Imoud.O.

The backlight power on requires a 3V apart from the 12V as its VCC. Some circuits would not work if DIM is also given a volt like this, in some other circuits it would not work if DIM is connected with a Voltage. Strange are the ways the circuits are designed. Such requirements have already been explained by me in several articles before! Many thanks for your comments!

Making board level repair more and more complicated; this is the motto seems to be adopted by the manufacturers, so that the customers will be forced to either go for an exchange or go to them for service. Many thanks for your detailed comments, dear Yogesh Bai!

Just one note. CRC 2-26 is not the best for freeing rusted on knob screws. Get a can of PB Blaster to add to your kit. Will come in handy, especially in wet climates.
