Hello!
Well, this one is a funny one!
A friend on mine brought me this set. The problem is that when the TV turns on, it starts changing channels alone, from 1 to 99 .Doesnt respond to remote , neither touch keys.
It also changes volume, and it's impossible to change input etc.
Opened the set, power board is OK , all values OK.
Disconnected the ribbon from mainboard to touchpad, same behavior.
Mainboard - BN94-02707U code : BN41-01538A
Mesured values on CN401. Photo attached with labels.
TR- 3.3V
GND
A5V1- 3.31V
MSCL- 3.3V
MSDA- 3.3V
KEY1- 3.3V
KEY2- values changing from 0.6V to 2.6V (+-)
LED_STB - always changing values cant even read it
The LED is allways lighnting up when the cable is connected, as when it does when recieving remote commands, but in this case just by herself.
The A5V1 has only 3.3V, what seems to be a problem.
The value of key2 is the one promoting this behavior I suppose.
The other values seem OK to you guys?
The set was connected to antenna, so I removed the Tuner to check behavior.
Still persists.
Any one got any set with these kind of issues?
Or any suggestions?
