Haven't really heard that flash ROM and RAM would go bad over time.
If you do decide to burn new chips, do it by copying the old chips.= Don't know if you can also copy over the EEPROM data too (tuning data). Bu= t that would save you from having to retune everything. Cost of chips and P= ICKit 2 or 3 should still be well under $100.

Per Jeff Whaley - we are also going to check to= make sure the A & B chips are completely inserted in the sockets.


We will look for any cracks on the circuit boar= d traces also.
