NEW SERVICE JUMPERS, NEW WAY TO READ ERRORS
INFORMATION: Due to parts availability there will be a change in the layout and operation
of the E8 and F8 chassis. This change can be identified by the location of the Service Jumper
pins.
Service Default Mode pins have been in coordinates D-3 since production start.
The pins are close to the memory IC 7601 (8 pin DIP). The pins are marked 0224/0228 in the E8
chassis and M24/M25 in the early F8 chassis. Later F8 use the same marking as the E8.
To Use:
Remove AC power and short the pins together.
Apply AC power.
A TV in shutdown (protect mode) will self-start and flash error codes on the power
LED.
Count the on flashes after the long flash and look up the error in the service manual.
SDM Pins moved to front of chassis (C-2 in E8, C-1 in F8).
The pins are close to the Micro-P IC 7600 (52 pin DIP). The pins are marked 0225/0226
in the E8 and M28/M29 in the early F8 chassis. Later F8 use 0025 and 0026 for these points.
To Use:
Remove AC power and short the pins together.
Apply AC power.
When the power LED is lit steady, remove the jumper.
A TV in shutdown (protect mode) will self-start and flash error codes on the power
LED.
