I do not know anything about these specific tuner, but I got the service manual of the TV chassis G90B SVHS. If, as Declan wrote, there is not much changed, you have the chance that things will be similar. The tuner used in that chassis is UV816U944L. The connections: pin6= +12.6V pin 16 and 17: IF out, drawn as a differential signal out of an amplifier and going to a band pass filtering circuit. pin 5= a feedback signal to the tuner, so probable the agc pin 13= I2C clock and 14= I2C data pin 12=+5V pin 11= connected to +33V via 22K. The blok in the tuner, to which it goes, is indicated with 2 diode symbols in opposite directions. pin 15=ground (or reference if you associate ground with soil). If you know the type number of the TV set in which the tuner was used, you can try to buy the documentation of it. In the passed I could easyly get the technical documentation of Philips devices. I do not know how this is now. I believe they organised the service out of their company. You can try the "klantenservice" or some firms who sell these documentation. (There was a firm in Nijverdal or Rijsen where in the passed I bought service manuals of several manufacturers). When you are interested let me know, I will search my archives. Recently I found also sites with repair information and sites who sell service manuals of several brands. If you want you can borrow my service manual of the G90B SVHS chassis. Let me know.
