Dead - Replace c707 and e994
power light blinking fuse open Replace C707 (1000pF/2kv)
No power, power supply geen led light on then shuts off E994 protecter 2Amp open. C707 SHORT
No power Replaced open protector E994 and blown C707

A place to start. Sounds like c707 is shorted or dry.

After reading the posts on this site, I felt obligated to post. I ordered the service manual for my 50UX58B TV, found the C707 cap with a hole in it and smoke on the cap next to C707. I replaced C707 first and had the same LED power up symptoms as other posts (no B+ LED and flashing red service LED). Next I check the E994 and it was open. Replace it and the TV is operational again. I did both component replacement without removing the main power supply board. Just clipped the leads and soldered onto the exiting posts. Thanks for your posts. Saved me about $2,000. Gonna order a High Definition Tuner for this TV this week because I just found out that it handles 1080i input. Ahhhh!!!! Should have read the users manual a few years ago!

I have the same problem with my tv. I have been looking for these 2 fuses. can anyone please let me know where they are located? If i can change these myself, I'd love to try.

Can the 50ux58B really handle 1080i? I know it says it has 1000 pixels vertical, but I cant get it to sync to any "i" modes?

Thanks

Same problem, and same simple fix. TV works great, as before. The shipping cost more than the parts!

Thanks for the posts.
