    My Samsung HCM4215W has the same problem, when you turn it on, the red light comes on for a few seconds then goes off. We put in new stk chips prior to this and it showed pictures clearly but after a couple of weeks it developed this power problem. Took it to a technician and they claim the motherboard is not supplying power. What can we do now??

    I'm not sure if all of us posting here have the same problem, but my problem is at least similar to one of the above. I posted this by itself on the site, but I think it's relevant here. Sorry for the double-post in advance.
    I have a problem described by at least two other users. As stated, the
    tv will look as though it is about to power up, will make the
    "power-up" noise, and then remain black, and then the power-up noise,
    in an infinite loop. In fact, this begins as soon as the TV is plugged
    in, without any prompting.

    Some clicking/ popping does occur
    while the TV is going through this process. I'd describe it as not too
    far from sounding like the normal clicks a TV makes while it is
    starting up.

    Earlier in the day (when the problem first
    occurred), if I would wait long enough, I would hear a second or 2 of
    audio from what I was watching, which would then be silenced, and then
    come back on, with no pattern that I could tell. That is no longer
    occurring, or maybe I'm not leaving the TV on long enough to hear it.

    red light below the word "TIMER" lights up erratically, sometimes
    blinking at an even pace, sometimes staying lit for a long time, and
    sometimes blinking quickly in and out.

    There is no smell associated with this issue that I can tell.

    the problem first occurred this morning, my image was normal and then
    suddenly went black, except for different-colored lines in a bowtie
    shape converging in the middle of the screen, before it went entirely

    Remote functions were still working earlier, as I was
    able to switch from playing a game to antenna A after the screen went
    out. (I could tell by the little bits of audio that came through.)

    sure if it's of any importance, but before this event occurred I had
    only used the TV for approximately 1.5 hours. However, I had used it
    for 4-6 hours straight about 8 hours before I began using it this

    Thank you in advance.

Try unplugging the red connector on the IC board (the board with the 2 stk chips) and try to turn it on, the picture will look pretty crappy but if it comes on it is probably the stkxxx-xxx chips replace with oem parts or you will be doing this again soon.

Sounds like you only have the stanby circuit function on the power supply. More information is needed to help further. Does it have a smell to it? Can you hear any relays tripping over? Can you hear high voltage build to the tubes?

Tv won't turn on. red power light is out

red light is on, but when the tv is turned on, it immediately shut down and goes back to the red light setting. It is like it blows a fuse or something to that effect.Post Solution

You have a bad power supply (AC adapter). Watch closely at the red light while turning tv on to see if red light momentarily flashes green, then back to red.
