Question about Audio Players & Recorders
The display only shows ''tuning'' flashing on and off. i have had this radio for a while and it has always worked great, but something happened to make it stop working. i cant use the tuning buttons, it doesnt respond and there is no sound playing at, even white noise. It is a CMT-spz90db model can someone tell me how to tune into the stations again?
This is not a solution but a suggestion - My Dad has this Hi-Fi and also has the same problem, unfortunately his warranty ran out 6 months ago. So, because of this I opened the stereo up. Inside there is a little (4in by 3in approx) PCB at the bottom back of the Hi-Fi above the CD section. This PCB is the tuner board. On this board there is another board (hybrid) with a BGA (Ball Grid Array) chip. BGA's sometimes lose connections between the pads on the board and the contacts under and on the chip. I am away in Germany for a little while but in 3 weeks when I visit my Mum & Dad again I am going to take the tuner board out and take it to work where we have a special heat gun for lifting surface mount chips. I am going to flux and reheat the BGA chip to reflow the joints under the chip. I am a Senior Test Technician with PCB experience so I DO know what I am doing. I let you all know how it goes.
