I'm working on a Rotel RX-875 with a non functioning tuner. It just scans for stations and finds nothing on FM and AM. I found that the supply voltage for the AM tuning chip, LA1245 was low, only about 2V, schematic says it should be 12-13V. I pulled the chip and it went up to 6. Replaced a cap and transistor (Q113, C171) and it is still around 6V with the chip pulled. The voltage entering the board is correct. I put the chip back in and it went down to 2V again.
Any ideas?
