No Remote Function Service Tip:
No Remote Function Service Tip:
TIP:
SYMPTOM:
When the set turns on and a picture appears, the bottom of the picture
shows the Input selection screen.
The Remote did not work.
The Front Function Keys did not work. (Except the Main Power Switch).
CHECKS:
1. Main Board: Reading the Key 1 and Key 2 lines found that Key 2 was at 0.8V.
Key 1 read normal at 3.3V.
(See page 124 for more details).
2. Feeling the Function buttons found that the right hand button (as viewed from the
rear) did not feel the same as the others. It was stuck.
FIX:
1. Removing and repositioning the button assembly freed up the button. The set
return to normal function.
(See page 116 for more details).
