How to remove c707 - Hitachi 50UX57B 50" Rear Projection Television

The Bearings are SEALED BEARING and are not lubricated externally.

Look here:HP-Compaq.

E 994 is a orange pico fuse---and the c707 is a cap----I can email you photos of both and tell you exactly where to find them on the circuit board--this is a very common and easy repair if it is your problem---I carry the caps and fuse in my tool kit wherever I go---You will have to unbolt the chassis and tilt it up--10 minutes--each of these parts has two leads that need to be unsoldered and then resoldered after you replace the parts.

I do this here for free so if you want the instructions take a moment and give me a vote here.

First what kind of monitor and model.
Second, don't use the monitor if you can hear and or see problems, have the unit repaired or replaced.
The caps are easy enough to replace if you have the savy.... With no model number I can't tell what kind of unit you have but if you mean C5707 and not C707, you have a Dell or BenQ monitor.
The C5707 is a 8 amp NPN transistor.
I have removed and replaced about 20 sets and used a TIP3055 which is a 10 amp rated.
You should have 4 to be replaced.
You also may have to watch what size the caps are, as if too long, they will hit the shield.
Good luck.

repaired two sets, both had a blown fuse (E???) and shorted capacitor (C707). These parts cost me $2.00.
Search for the keywords Hitachi and C707.

If cap value is 1000 pf ( 102k ) 2KV, beef it up ! I use Sony part # 1-161-754-00 ....102k 3KV.......Note: sometimes shorted cap
is hiding under dried gob of placement glue............
Make sure pico fuse is correct amperage.......T.

1. if you choose windows vista instead of xp you can solve this issue. the drivers are available for vista only. visit www.hp.com for further proceedings. else 2. when you use xp the drivers must be updated from device manager. if You give the installed location of the specific drivers you can easily get what u need.....
