Hi there
Try resetting the TV by unplugging everything, and wait 3 minutes, then plug in the power lead only, and turn it on.
Hope this helps

Samsung 42'' HCM4215W image looks like it's in #D


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

Samsung HCM4215W,shuts off.


Sounds like a short in the power wire, it takes about 10 to 15 minutes to warm up then shorts out and when it cools down you can watch for 10 to 15 more minutes before it shuts off again, you need to take it in and have the powercord replaced because this is very hard to do from home and one mistake can make the whole tv not work.

Practice visual acuity technique!Check signal PCB for CRT coolant leak.Cleaning circuit board may restore normal operation,but one or more leaks will cause problems to re-occur.Change leaky CRT(s).
