I've got this digibox with 13V present at the lnb output with "No Signal" on screen. I've confirmed the dish is ok with another digibox. What could be wrong here?
Thanks

ZIF chip or PSU caps ?

I've changed the psu caps in this digibox already. Whats the circuit ref for ZIF chip? Do you know where I can obtain a service manual for this digibox?
Thanks
The ZIF chip is the big fella in the digital tuner module, and requires specialist infra-red top and bottom soldering equipment to replace. Friend of mine used to have all the gear for it and did lots of them on various manufacturer's boxes, and I'm pretty sure that Grundigs were amongst them. Don't know whereabouts you are, but if in the UK

offer tuner and I think whole digibox repairs. Check out their very helpful website. You might also like to take a look at Martin Pickering's very good website with technical help forums
