    Same here. Same exact set. Just happened. Set quit while it was on. I smell smoke. Please email me at dot_calm@hotmail.com if you find a solution.

    Same here. I unplugged the power cable for 1 day. Turn it on, it actually works for a while, then the same problem again.

SOURCE: Samsung HCM4216W Power Problem

Vern,
The most common problem for those symptoms are convergence amps. That unit takes two stk392-040 Sanyo Ics and will most likely require that several low ohm resistors (3.9 ohm-2w) be tested and possibly replaced.. There is one last thing also, a pico fuse at Fd102 (3.5a) that sometimes opens and would need to be replaced..
The convergence board in these is easily removed, so an in-house service call could be done...
Hope this helps!

SOURCE: red blinking light

It's most likely convergence -- the small board up and to the right inside the back of the TV, which has two large amp Ic's attached to it..
Unplug the +/- 20v line on the fron left corner of that board (red in color) and then try and power on the set... If the set comes on the board needs to be repaired and it's an easy unplug and two screws that mount it inside.

SOURCE: HCM4216W...replaced convergence board...still no

Do not take this the wrong way--I have seen several people make this kind of mistake--why on earth replace the board when you can buy the pair of chips for under 15 dollars?

At worst--there will be other than the chips a fuse on the board near them bad...

Look at the old board if you have it--this model should use STK-392-040 chips--I can tell you a seller who has them on EBAY---my point is these sets it is almost always better to just replace the chips and fuses if needed--

Do you have the old board? Can you return the new one for a refund?

I have repaired hundreds of sets with convergence problems and only a very few needed to have the board replaced.

I understand why this happens--people think it is easier to replace a board but they are wrong--it always costs more that way and presents problems.

Give me as much info as you can and those chips are readily available. I can tell you name of the seller I buy mine from--got several of the chips your set uses on hand right now.

If this helps you rate this solution as I do this here for free.

If you have questions or need any help ask me--I am here to help.

The red "on" light is blinking and the TV


a suggestion: unplug set and try to turn on again; if power light blinks does it blink in a sequence?

3 blinks repeated will mean a problem in the Convergence area.

5 blinks repeated will mean a short on the 140 volt line.

These are the two most common error codes.

Red and Blue convergence issues cause triple-image


This sounds like your convergence chip is bad. If you are good at soldering you can order the replacement kit from www.tvrepairkits.com and do it yourself.
