Title: Sharp stuck in stanby
Post by: Vlad on February 01, 2011,16:20:03

Hello
I got a Sharp LC-26D44E-BK stuck in standby.  When I conected the TV to mains the green light is going on for 5 seconds and after is going to standby. There is no sound or picture.
I check the PSU and is looking ok.
Any idea?

If you could see the picture in a sec. and then black screen,
you got a inverter problem. When you enter the service mode you disable
the protections and thats why the green led is on. Change the capacitor C7554.
Look at page 4

I change the capacitor but the TV is till the some. It looks like that one of the tubes will be faulty.
Thanks for all help
