    Samsung LN40B500P3F - I Think I Screwed Up

    Hello All! I recently aquired this tv because it had an issue with the picture coming on for a split second then going dark again. I pulled the back cover to poke around a little and have done some damage in the process. I removed the PS/Invertor board to have a look at the back side, but in the process broke the end off the very top lamp. Are these lamps/bulbs replaceable? A quick google search came back with nothing. Will the picture still work with one dead lamp (assuming i fix the original problem)? Thanks in advance for the advice!

      That's excellent, thank you! Will I be able to continue testing for the original problem before i replace the lamp, or does the lamp need to be in working order to perform any tests? thanks again!

        The lamp really needs too be replaced first do any of the other lamps look bad ie black ends etc.
