I try to turn on the tv but all it does is make that click sound that it always does before you turn it on but the screen stays black
Can t
someone tell BMW which board has the cap on it for the +140 problem. Seems easiest to simply replace a complete board than find multiple bad componants
Let me know if the power light on the front of the set blinks----most
of these sets have a error code--Also confirm actual model number to me
and I will assist you.
For example: 1 blink a pause 1 blink etc is short on 140 volt line.
A sequence of 3 blinks pause, 3 blinks etc is SHORT PROTECTION---I CAN INSTANTLY TELL YOU WHAT THIS MEANS.
There is one other very common problem with this model---There is a CAPACITOR in the high voltage
circuit that fails a lot on this set---it is not an expensive part and I can tell you how to find it--on a few sets it will take a transistor near it out--
Usually if the cap or transistor are gone you may not get a error code----if just the cap is bad sometimes you will after a few minutes with the set on see a band of white noise to the middle or right side of the screen----I HAVE SEEN OVER 50 OF THESE SETS WITH THIS CAP BAD.
I can, if you are able to solder etc---tell you the best way to get at the suspect parts.
Let me know what you have found.
