Sharp Aquos LC42D77X 2 short blinks

[Tommy2shoes]

Hi fellas have a 42in Sharp Aquos with 2 short blinks on standby light. what I've read on cpl other posts is 2 short blinks is inverter/lamp error. This model has only one long inverter board and looking at it I noticed a brown burn mark. Closer look showed on back of board notice the arc hole just wondering if the lamps in picture are stuffed having that seeing they have that black little ring around them. My guess is Yes and its a throw out ?

Well i've been looking everywhere can't find a pic of a blown backlight . Anyone tell me if I should try replacing inverter board or not waste my money. Thought about building a test jig like Bud has shown but don't have a spare PS and doubt I'll use it much. Any advice appreciated. Cheers
