Hi,
Try this.
The eeprom in question is IC 1803
(24C256) 8 pin smd and is located on the underside of the main board near the
common interface.
The clock and data pins are pins 5 and 6 and are identifiable by the 100 ohm smd
resistors connected to each of them.
Fit a shorting link (on long wires) between the pins. Reassemble the chassis.
Switch on, and then remove the short (cut the link).
Bring the set out of standby.
Now access the service mode as follows- Using the remote control, switch to
standby, then press info, menu, mute and power.
The set should start and display the service menu.
Using scroll keys select item 8 and enter by scrolling right.
Select "tuner" and set to auto. Revert to previous screen by pressing menu. Now
scroll to "reset" and enter by scrolling right.
The set will revert to standby. Power back on and tune in stations.

Hi Chrissie, the eprom is surface mount on underside of main board below the expansion slot it should be marked eprom, the 2 pins are bottom right as in the legs would be facing into the board not the legs nearest edge of pcb,
I have found in 5 sets 4 needed eprom replaced, good luck
