Hello ! I'm looking for the RGB2CRY algorithm. In fact, in the Jaguar Technical Reference Manual, it is advised using a 32768 element lookup table but I don't know how makes it. How could I make it ? Thanks. SCPCD.

I am making my new website and I add tomorrow the tutorial with more informations for this reparation in french and in english. Regards.

Few years ago, I have bought a died Jaguar. This Jaguar was died as yours : an error of polarity of the AC/DC converter. I have repared it and now it is my special development and test Jag. I think that it is possible to repair yours as mine. To prossess to the reparation, you must have experiences in SMT soldering : It's very important because componants on motherboard are very little and 2 componants to change on 3 are SMT. 1) First, you must open the Jag (and the iron cage). 2) Once the Jag is open, search the capacitor C134 (330uF 16V) just above the U38. In my Jag, this componant was blow up. You must remove this capacitor. Do not replace it before the next instruction : it will be easier to replace the next componant. 3) You can see the U38 (MC34163DW) in the right of the MC68000 and below the C134. This componant is a power switching regulator (9V->5V 3A MAX) and it doesn't like very well when the polarity is inverted. So, it is it that toast. Maybe you could see a distortion on the surface of this componant as shown below (maybe not as important as mine): You shall replace it with the same part. !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!WARNING : BE CARFUL WHEN YOU SOLD SMTs!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! If you don't find the MC34163DW you can use the MC33163DW, the difference is in the operating temperature range : the MC34163DW = 0 to 70°C and the MC33163DW = -40 to 85°C. When you have replace the U38, you can replace the C134. 4) Another componant shall be replaced : it is the REG1 (LM78L05ACM) (in the sound circuit). This componant is a DC/DC converter (9V->5V 100mA MAX) and it is used for the audio power. As the U38, if it is died, you can see a distortion on the surface as below : If it is died, you don't have sound when the Jag works. You shall replace it with the same part. Normally, if you replace their componants with success, your Jag could work. The reparation cost 5,2 euros HT for the France. Regards.
