DLP Chip Replacement, Picture\Focus Adjustment

by jwkoeberlein / April 3, 2010 2:19 PM PDT

I just had the DLP chip replaced in my HLS4266XW tv due to the white dot issue. Service was excellent, called Samsung and they opened servce ticket(100% paid service for my oow tv), repair shop called me that day, repair guy was at my house in less that 24hrs and white dot issue is gone thanks to the new chip. HOWEVER, the picture on my tv is now fuzzy\hazy especially when there is text on the tv. I wrote my settings down prior to the chip replacement and I set them back up after the chip replacement so I know they are the same as before. The picture just is no where close to as crisp and clear as it was before the chip was replaced. The picture just isn't sharp now. I've read that the repair guy should have re-focused and\or adjusted the picture after the chip was replaced as it is standard to have to do this after any chip is replaced? Is there any truth to this and if so any recommendations as to how to do it myself or is this something a tech will have to come back out for. I have the HD package and the fuzzy\hazy picture is obvious on all HD channels and with both HDMI and HD Composite connections. Please help!!

DLP Chip Replacement, Picture\Focus Adjustment

jwkoeberlein,

As quickly as possible, I would call back the service technician who worked on your television and request that he come back out to adjust the television.

If that's not able to happen, you may have to contact Samsung again. But I would strongly recommend you call back the technician, as they usually warranty their work for a period of time, and particularly because the unit is out of warranty.

Ditto. DLP chip replacement

I just replaced the DLP chip on my Samsung HL67A750 and I am also disappointed that the picture is not as sharp as with the old chip. I am trying to find out how to rectify this.

Blur on screen after DLP chip replacement
by joeinhb / September 27, 2013 1:48 PM PDT

ronrak and others with the blur on the screen.... I just watched a video on Youtube by Shop Jimmy, they said that you need to ensure that some ring needs to be aligned (go see video)... I am about to replace mine myself, it does not look hard to do, just be patient and take your time.
There is also a different video by a regular guy, both are worth watching to help out
