Power issue Put in the Tv Repair kit which includes the C707 and the e944 Pico everything went in fine.checked with meter good continuity..any other help would be great..Board lights up green led then just shuts down..next Step??

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.

hello. sorry it took so long to get back to you. well. the first thing to do is to check the fuse. did you.?

You can get the parts from www.TvRepairKits.com. They have put together a kit that includes the parts and instructions to fix the following models (50UX58B, 60UX58B, 50UX58K, 60UX58K, 50SBX78B or 60SBX78B). The kit includes the E994 pico fuse and the C707 capacitor.

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.

If you have Hitachi model number 50UX58B, 60UX58B, 50UX58K, 60UX58K, 50SBX78B or 60SBX78B and you have the following symptoms you may want to grab a repair kit from www.TvRepairKits.com. They have put together a kit that includes the parts and instructions to fix these models. This is a fairly common problem with the above model numbers. It is typically caused by a blown capacitor and pico fuse. Again, you can get a kit from the above address. 
Here are the symptoms...

Primary Symptom: No Audio or Video. Power light will come on briefly then shut off.
Other Possible Symptoms : The green LEDs on the circuit board light up for a few seconds then turn off.

Hope this helps,

You need to check E991, E994, Q777, for more info ctechnicians.com

Linda,
A VERY common problem with this unit is a small blue disc cap C707 (102 @ 2kv) tucked in front of the horizontal output transistor. It usually has a small pin hole burned in it when it goes out. The cap is actaully part of the scan circuit and it changes in value over time and becomes unstable then opens, usually taking with it E994 a small pico fuse.
I wouldn't spray too much duster in there for all the dust it will create. You'll be dusting the house for days. But it won't hurt using a can of duster or air to blow it out if you want...

Common problem. You can get a repair kit that includes the C707 and E994 + repair instructions from www.TvRepairKits.com

RED light is protect circuit = do not disable !
Look for C702 near flyback transformer - might be hidden in
glue = check it = if shorted, replace 102K / 2KV with 3KV =
Sony part # 1-161-754-00 and replace E994 pico fuse.....T.
