Samsung HCM4216W Power Problem

I have a Samsung HCM4216W TV and it now won't respond when I press the power button. The "timer" light blinks for a short while before it too, quits. Could ther be a fuse to replace or is this more serious. I cannot say what it did before this. My brother bought it used. Thanks in advance. Vern

Re: Samsung HCM4216W Power Problem

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!

I have a Mitsubishi WD-52725 DLP TV and green light (timer) is rapidly blinking after a power outage and set will not turn on. The bulb was replaced a month ago and it has worked fine since. Now it will...

make a System Reset process. To do this;
If the TV will not respond to either the remote control or the front panel controls and/or will not power Off, press the SYSTEM RESET button with a pointed item like the end point of a paperclip. The TV will turn Off and the TIMER light will flash quickly for about one minute. When the TIMER light stops flashing, you may again turn on the TV. The changes you made the last time the TV was on before you used the SYSTEM RESET button may be lost, however, the changes that were previously saved are not lost.

Timer light blinks on and off and tv wont turn on

Resetting the TV
If the buttons on the remote AND the buttons on the TV case do not work (channels do not change and you cannot open or navigate the menu), the TV has stopped responding. Reset the TV as follows:

Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.
1. Unplug the TV power cord from the power outlet.
2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the TV power button for five seconds.
4. Plug the TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the TV is responding again.
6. Turn off the TV and reconnect the devices.
7. Turn on the TV.
If ever resetting is no effect then the problem is in the "DM board"
The constant blinking green light means that the TV is not booting up. This is a common problem on this set. Hope it may help you; Regards, VOTIT

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.
