Hi I have a Samsung 2043 NWX which recently stooped displaying picture.
It started displaying blue and black screen when connected with VGA cable and "Check signal cable" when no input connected
I opened the circuit Board and replaced the blown Capacitors with same ratings.
( The power supply circuit Board)
When connected with input like TV tuner
( Input connected)
( Input connected, menu options working, but picture adjust does not work like horizontal and vertical adjustments, only brightness and some other options seem to work)
( No signal connected )
Now also the problem persists, I see that the voltage reading against each capacitor is less than what it is designed for, example 16 volt is reading just 6-8 volts and the voltage across the 3 diodes is just 2.5 volts.
