I have a wacom cintique 24HD, an expensive monitor i got fairly cheap in a scam of sorts, i was sold a dying monitor, the tubes are on their last legs, they only really reared their weakness once it got really cold, which took a while since we had unseasonably warm weather from since i bought the monitor over a year ago until now. I cant send it in for repair because im poor and i have no warrantee, the thing weighs a ton, and i have to cover shipping, with no guarantee itle be fixed.
Anyway, monitor works fine (displays a picture) but the backlight, which operates almost completely independantly, often fails to start and leaks HV from the cables, indicating that the tubes are bad, i tried replacing the capacitors but it didnt work, although oddly heating the capacitors up sometimes helped it start i think this was just coincidence, or, causing leakage that helped somehow.
Ive opened the monitor several times. everything is attached to an aluminium plate which sits on the backlight i asume, which appears to have its edges all wrapped in something like packaging tape. There are 6 inverters powering 6 pairs of leads, i asume that there are 6 lights.
what do i do? is there a proper procedure for replacing the tubes? like, in general for backlights?
Ive been told i should be able to just yank it out and stick in a new one that its that simple. Is it?
if it comes to the point i cant identify the tubes ill just replace them with LEDs, when one tube fails it doesnt cause uneven lighting. The driver just takes PWM and has a single feedback port which outputs 5v as long as the inverters are running to indicate its ok.
So, how should i go about taking apart the backlight and accessing the tubes? This is actually a common problem, this model of monitor failing in this way after a while.
I forgot to mention that i need to do this non-destructively, ive spoken to wacom, they said as long as i dont cause damage suggesting i caused the failure, they will repair it. I want to keep that option open which is why im not just arbitrarily cutting and prying things apart. Ill post some photos if neccesary.
