Sharp LC-40FG2241KF smd resistor values

[Judderman69]

Hi, I'm trying to repair my grand daughters Sharp Aquos LCD TV LC-40FG2241KF which died suddenly. I have repaired a blown pcb track from MOSFET driver IC (LD7537) pin 6, replaced the IC, MOSFET, current sense resistor RB148 (0R27), RB106 (68R0) and fuse FB1. Smd resistors RB107 and RB105 are also open circuit, does anyone know the value of these and anything else I should look out for. Your help would be much appreciated.

Bump. No Sharp techies about? The main PCB TP.MS6486.PB711 seems to be in very short supply, and it would be a shame to bin the whole set just for a couple of smd resistors.

I think the chances of getting an answer to such a specific, technical question on here are fairly low, unfortunately.

Have you tried searching online for a service manual ? There are also specialist sites that you might have more luck on such as the 'Technical Forum' on badcaps.net which I have used for TV troubleshooting in the past.

Thanks for your comments mikej I have found a similar schematic online but it doesn't show any component values, dam you Sharp! I will defo try badcaps.net what do you think of [H]ard Forum?

I've not heard of that one. I think Badcaps is an American site, so you might be reliant on the same (or a similar) model being sold in the USA or posts from owners from other parts of the world with similar issues. Worth a quick look at least, either way. There were some VERY knowledgeable people posting on there when I was looking into my Panasonic plasma issues a few years ago
