    I have a Samsung DLP Model HLN507WX/XAA This Television will not turn
    on, except on rare occasions. Three LEDs labeled temp, timer, and lamp
    start blinking a few seconds after I attempt to turn the set on. I
    just replaced the color wheel, tested the door safety switch, and the
    thermo switch next to the color wheel, and they check good, I don't
    hear the lamp ballast attempting to come on, but because there are
    times when the TV AND LAMP will turn on, am I wrong to assume the
    ballast and the lamp must be good, and could they be intermittent?
    The only voltage I was able to measure going to the Ballast was about
    385 volts DC.
    Any tips would be greatly appreciated.
    Thanks

    What does the user manual say for that LED pattern?
    what is the button sequence to reset the bulb expiry?

    Customer didn't have a remote, but Samsung thinks its the DM board. If
    I find any additional information, I will be sure to post it here.
    Thanks for attempting to help

    My Tech friend told me to point a hot hair dryer on the DM board to
    see if this made the TV start working, and it did, but now need to
    find our why.
