I have a Samsung HL-S5679 LED DLP TV. I am getting some green shadows showing up from all sources. I found someone having similar issues in a user forum, who said the tech replaced the "digital board". I want to make sure I get the right part. Which of these is the part I need? Digital Video Board, LED Driver PCB, DLP Chip, or DMD PCB?

Its the DLP IC chip itself that is bad. The DMD board is where the chip resides but if you order a board, it will come without the chip. Its not cheap and the replacement is tricky because the DMD board must be removed and then an alignment of picture centering will be necessary.

Before I can suggest anything its best if you can get me an image of the screen with the tv on so that I can see for myself.

This is something of an urban myth....The "DMD chip" is actually the LCD display IC for the set; yes I have seen some listed on EBAY---still a myth----they are replaced (when a light engine is rebuilt in a space age lab or environment) under exacting conditions----if positioned a micron off in any direction picture will be tilted in some way---this is also not like changing spark plugs in a car, if you have a optical engine issue like spots etc, either get a rebuilt engine from Mitsubishi or buy a new set.

They usually require some parts for old engine (mounting brackets etc) be installed on new or rebuilt engine.

I did see the "chip" for another model listed on ebay today.(100.00 PLUS)

I understand the engine is expensive, I replaced a lot of them when the sets were in warranty---more Mitsubishi than any other brand with Samsung a distant second.

I am sure Mitsubishi does not offer the part for sale--they want to sell a tested rebuilt engine only.

I wish you luck but have little hope you will find a "part" other than the whole engine.
