LC-24LE250

Standby On/Off Problem

Problem:

Device can not boot, TV hangs in standby mode.

There may be a problem about power supply. Check main supplies with a voltage-meter. Also

there may be a problem about SW. Try to update TV with latest SW. Additionally it is good

to check SW printouts via Teraterm. These printouts may give a clue about the problem. You

can use Scart-1 for terraterm connection.



No Signal Problem

Problem:

No signal in TV mode.

Check tuner supply voltage; 5V_VCC, 3V3_TUNER and 1V8_TUNER. Check tuner options

are correctly set in Service menu. Check AGC voltage at IF_AGC pin of tuner.

14.

Service Menu Settings

In order to reach service menu, first Press “MENU” buton, then write “4725” by uisng

remote controller.

You can see the service menu main screen below. You can check SW releases by using this

menu. In addition, you can make changes on video, audio etc. by using video settings, audio

settings titles.
