[QUOTE="mindfield, post: 694380, member: 350855"] Hi from Christchurch, New Zealand.... The Dreambox clones have three generic problems:- 1. The tuner modules suddenly go deaf; the Signal to Noise Ratio (SNR) dies and you ain't gonna get nuthin' on THAT Dreambox. Ever. We have just purchased and installed a new tuner module from China. They don't cost much but the installation does involve some very gentle and fine soldering skills with a quality electronic temperature controlled soldering iron (Weller tools make an excellent one that won't burn up the surrounding printed circuit board). It is a reasonably big job that also requires the use of personal electrostatic discharge protection straps while handling the Dreambox. The replaced Tuner is now giving me a provincial New Zealand Rugby match in the repaired DM500 on the workbench beside me. Other generic faults are that the voltage regulator transistor (Q72), at the back of the tuner on the PCB give up the ghost and won't supply the volts for the LNB or the positioner. Replace Q72 for about $20.. and it'll go again. Another common fault is the loading of bad or incorrect images and the Dreambox suddenly looks like Monty Python's dead, deceased parrot!. Do a google search or YouTube search for the cure and JTAG it, make your own JTAG Cable, It's really easy! A German trader at also sells a JTAG cable but why spend the money when you can easily make your own. I'm on Skype if you need to talk... regards, zl2rob, Robert. [/QUOTE]
