Question about Samsung HCM4215W 42" Rear Projection Television

1 Answer

HCM4215W SAMSUNG TV TURNS ON AND TURNS OFF AFTER ABOUT 5 SECONDS

I have a hcm4215w tv that I got from a friend with a convergence problem. I replaced the complete convergence board about 8 months ago and has been working fine. Over the weekend, the tv was on and it just turned off, then it powered back up and turned back off. It will keep doing this until you turn it off or unplug it. I unplugged the connectors on the convergence board and tried it again and still does the same thing. Is there another common problem with these units that I can replace or is it more involved to repair? Also when the set turns on for the short period of time, the audio turns on and you can hear the station that it is on but it turns off before the picture comes on. Thank you.

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Low ohm resistors are open or poor solder connections on the bottom of a convergence IC.

You need to look at resistors in good light with magnifying glass. Bad ones may show as discolored or burnt.

The repair needs someone that has the schematic for the convergence cct, and can replace the burnt resistors or replace the whole convergence board.

If you are near Calgary, call me, if not, find someone that has done it before, preferably many times.

They are parallel in circuit and measure around 2 ohms when ok. Check the fuse associated with that circuit. FD101S 3.5 A

It's simple. Your TV does not like you. Perhaps you need to speak kindly to it before you force it to watch BBC for hours. Buy it a scone.

Ill have to look up the part numbers , but it is a common problem caused by the convergence board at the back of the device. replace the TDA*** for the color that is faulty and the problem should be solved.
After replacing the TDA*** you need to adjust the convergence again and perform an auto-fucus and convergense adjust again

Cannot not line up the red and blue lines on my samsung projection tv. it is a 2002 samsung tv


Needs new convergence amps and possibly a few low ohm resistors.
Those Samsung amps usually run hot to the touch and sometimes only last 4 to 5 years depending on usage.
