Have a mitsubishi WD-60735 TV. Replaced the DLP chip because of white spots. When I turned it back on I have sound but don't have a picture. Just a white horizontal stripe with black spots.

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.

No, but you can replace it.

A common issue and it may be your problem is dust and dirt inside the unit---the set intakes air from the front and exhausts it out the rear==I have seen several of these sets where removing rear cover and taking stthe set outside and blowing it with a air compressor clears the issue.

Fans and other critical items that get clogged or coated with a moderate amount of dust will cause this issue.

This is the reason I do not nor will our shop do this, considering cost of engine rebuild versus this not worth the trouble---only thing I can suggest is go over all you did to make sure no bad connection etc.

SOURCE: we just replaced the DLP chip in our mitsubishi 1080P tv because we had white spots all over the screen. Now after replacing the DLP chip we have no picture at all but we have sound. Help?

Likely you either forgot to reattach your color wheel ribbon connector, or have it on upside down. It's the tiny ribbon cable behind your circuit board that will come off as you pull the board away from the DLP chip.
