Replace tuner REV K with L3, problem

[carddreamer]

I have a DM800 with a tuner Rev K and this tuner gives me many problems with "tuner failed" errors. I have bought a second DM800 with tuner Rev L3 and this receiver is much better, absolute no "tuner failed" errors. My question is that I have then bought a Rev L3 to the old receiver, but I can?t install it. It is rebooting all the time after I have installed the new Tuner L3 instead of Rev K. Is there any problems with changing those 2 tuner?s. Maybe a motherboard problem or something else. Has anyone have had succesed with that change?? and how did you do it. I have no problem with the installing only the constant reebooting

yes old rev j motherboards have problems with newly made tuners as there built for the rev L motherboard

basicly you need a old L3 tuner
