sharp lc-30hv4e backlight

[wsdgss]

hello,

the last three days my lcd tv turns dark at the right side of the screen, the left side looks oke. sometimes it give this error and sometimes it works just fine. i have look at the inverters, the output of them is about 1.285K.Ohm. Does anybody know what is happening here? Is there a service manual, or some sytematic?

greet,

Sander.
