Hi,
I guess my earlier post fell thru the cracks, but if anyone has any idea how I might fix this problem it would be much appreciated.
After faultless operation for some years the screen is now completely dead. On switch-on, the green light flashes 10 times and then goes solid green but there is no life at all on the screen, but I do receive sound. I'm sure it's a power supply problem, but here in Andorra there are no repair facilities. The plus 15 on the Powerwel board is up at 200 volts and the other voltages are close to zero.
Monitor is MZ-42PZ24 (ABLLKS). Full part No. PDP42WVSN3. The three PS boards are:-
PDP 020417. 42SD3_YSUS
PDP 020417. 42SD3_YSUS
PW 1450 Rev E (Powerwel)
There are no fuses that I can see on any of the boards except for a soldered in fuse on the Powerwel board with an adjacent thermistor. Both components appear to be ok. I presume I will have to replace some boards.
On a UK web site I have found the following replacement boards, but they don't quite match the numbers in my monitor. Are they likely to be suitable? Finally, are the boards directly "switch-on" interchangeable, or
are there technical adjustments required after replacing the boards?
Original Board Numbers

YSUS:6871QYH036A

ZSUS:6871QZH041A
6871QZH041B New Version Supplied in Kit 6871QZH041B
Any assistance greatly appreciated
