winner ad-9800b
Hi
Have a Zeberg (Tone Winner) AD-9800B that will not start up.. It's the data part that's not working, have checked all voltages and clocks and they are ok.. The JTAG interface is working on the uP (S3C44B0X Samsung ARM7)
Then pushing the on button or remote the sets relay clicks and the display light up with a black screen and blue led some seconds and then turns off, read led. Two times has the set start up after latching a lot with the JTAG but after turning it of and trying to start again it is as usual..
Any ideas what could be the case or more fault finding tips/tools?
