I bought a 8753ES about a year ago and yeah Im about to deal with those issues.? I think I paid around $3500 for the 6ghz model.??
My screen is dim so I have a new led backlights to replace the tubes with.? However I maybe needing to build a 5vdc boost converter to run the led strip lights.??
I also have had once my screen invert on me.? Annoying to say the least, but have yet to break the cal stickers to opener up to work on it.??
