Acquired a samsung LN40b60r3fxza that had sound, all input, and a quick backlight flash when powered on. Used a Xenon bulb to check inverter and everything looked good. I continued disassembling and got into the backlight case. Maintaining all connections was able to power up the tv and notice that 1 bulb was out and one was yellowish. I changed there locations to confirm the inverter operation and the bulbs maintained the same. Ordered 2 new bulbs and we now have a nice 40" tv. Thanks for the trouble shooting tips(the xenon bulb) from Badcaps..
