Re: Samsung DLP HL-P6163W vertical black lines

Hi, I am not sure if Samsung will repair it for free. But I am sure what the issue is..... On your post you mention that the lines have a mathematical arrangement, 8 dark lines and 1" of light. This is a issue with the DMD board (Digital Micro-mirror Device), this board contains the DLP chip. P...

Re: samsung DLP SP50L7HX

Hi,

Clicking noise is definitely the ballast, if we already replace it and still doing it, check the voltage coming from power supply to ballast it should be 350V, power supply might be sending oscillating voltage and might be shutting down if it goes under 350V. :geek:

Hi,

I will definitely try the lamp first. This TV lamps do have a lifespan of about 6000-8000 hrs, and by 5 yrs is most likely that we already reach that limit.
Ballast also clicks when is not able to turn ON the lamp. 95% of the time replacing the lamp will make the trick!!

It might be a bulb issue, or related with the DMD since this board creates the picture.
