Hi Matt,
The dim screen is actually a pretty easy fix.? What happens is that there is a mylar film that acts as a reflector around the lamp that ages and curls up around the lamp over time.? All you have to do is remove the front panel (about 5-7 screws, top and bottom), unplug the connector to the unit, remove the LCD module (4 screws I think) and then finally the backlight (2 screws).? You carefully remove the florescent tube then replace the damaged mylar with a little strip of aluminum foil which can be held in place with some tiny pieces of foam at the end if you like to keep it from moving around.? It's about a 15 minute job if you know what you're doing.? I actually recorded a video of the process that I'll try to get up on youtube.? ?You can replace the light for about $20 as well, but I find that this is rarely required.? The mylar replacement usually does the trick.
As for the reversed screen, even easier.? It turns out that there's a connector inside that front panel that goes bad over time.? It is a 8 pin flex to board connector (z axis) that is about 3-4 inches in length.? It goes from the keypad side of the panel over to the LCD.? Just unplug it and replug it in 2-3 times and you should be good for at least 2-5 years of additional use without any issues.
By the way, I still have two 8753ES 6 GHz units that I repaired up for sale at the bargin bin price of $2500 per unit (or a fair offer).? I still think that they're a great way to go if you don't need a lot of speed.
