Hi Guys
Remember I'm a novice ... .. ..
I bought myself a faulty DAB radio on Ebay for 99p to see if I could find the problem and repair it .. .. I must be learning something from you people because I went straight to a blown chip on the power board. I took the power board out and ran 5vdc through the set from my bench PSU and the radio leapt into life. Simples !!
Now, my question .. .. The hole in the blown chip ( see pic ) is just where the ID would be and looking at the solder side, judging from the amount of flux and solder on the pins, it has been replaced before, so maybe there is something else going on causing the chip failure ? I'm planning to replace the whole board with this .. .. ..
**broken link removed**
My bench PSU measured load with all leds on and max volume at just a tad over 200Ma and the output on the old board is marked 5vdc .. .. .. ..
Will this do the job OK ??
Thanks
