All Sony 125x/127x projectors have digital convergence, on screen menus, come with a wireless remote. The performance of the series of sets is quite similar in both setup and operation.

The Sony 1270 came out first in 1990, and was Sony’s answer to the Barco 800. The Sony 1270 scanned to 75 Khz, and used the Sony 07MP electrostatic focusing tubes. Depending on whose literature you read, the 07MP tubes either were 7” or 8” tubes (we tend to call them 8"). The lumen rating also varied from 650 to 825 lumens depending on who you believed.

The Sony 1252 and 1272  models are the newest in the series.  The 1270 has 9 points of zone convergence as does the 1251 and 1252. The 1271 and 1272 have 21 point of convergence, which make the later models a bit more desirable. HOWEVER… if you do a careful convergence job, the sets with the earlier 9 point convergence can look just as good as the later sets. 21 points of convergence is handy if you're too lazy to do a careful set up… :)

The Sony 125x/127x series are complete workhorses, failures on these are relatively rare. The internal layout are all very similar.

Extra information:

How to enable progressive scan component on an IFB12 optional input card: On the dip switches located on the input plate turn on switch 2 and 3 and leave all others off. Jumpers 3 and 4 are labelled Sync on one side and Video on the other. The default is Sync but you want to move these to Video. Jumper 5 is labelled HD on one side and GS on the other. HD is the default and you want to move this to GS. Then just install the board and hook up the cables according to the labels on the rear of the IFB12 (Y, Pr, Pb). You don't need to adjust anything in the on screen menus. This will allow your older Sony 125x/127x set to accept 1080i and 720p over component.
