ERRO1: No CA found!

[Julez101]

In desperate need of help guys please! I was told by somebody that the max232 chip might be faulty and to replace it. Does this make sense.

I have looked at my dreambox and I have a max3232 cse1125 chip and then I have found another component laying around which has a max 3232 cse1108. Can I replace the dreambox chip with the other chip that I have found. They are both 16 pin and from what I can see, both are used on the rs232 connection on both boards. I really hope this might help. I can also upload photos if you like to show you that the board is in new condition with out any visible fuses blown. Also I have tried 3 different serial to usb cables with the null modem, I have also tried an old pc with the null modem only and no luck. I would really love to get to the bottom of this problem!

Problem fixed! I did as I was told and replaced the max232 with an extra that I have and then used Optiflasher to fix no ca and imediatly the box was found! Soo glad that it worked! After all the problem was the max3223! Anybody with the same problem and no success on this matter just replace the max232 chip, The U17 and all will be brought back to life!

This here was an easy to follow diagram with the schematics for the dreambox dm800hd box. I removed the max3223 chip from an old ck3 pro that I had laying around and replaced the dreambox chip. This solved the lan light problem as well as sorted the communication out between the box and the PC both with hyperterminal and dreamup within seconds! Only things needed for this repair are soldering skills as well as a max3223 chip with 16 pins or some boxes are different so read the chip under U17 on the motherboard and replace it, problem solved
