My LG ref. control has something wrong! it is elctornc setting, with 5 levels! suddenly 5 levels will become on! but the cooling is very less, almost it is not cooling! Freezer is manually controlled, by a weal from 1 to 7. freezer is ok, the ref, only has a problem. thank you

MAY HAVE a bad cold control thermostat, however the setting should never both be set to high. 5 may be a bit to high they should be set at medium. otherwise I suspect u may have a bad control board issue not communicating with the cold control all can be checked with a multi meter

The cold control needs replacing. Thats the knob with the numbers that turn the Ref OFF and ON.
What I do is call my local Appliance Parts Store with my model no. They are extremely helpful .
Get freezer and ref thermometer. Ref is probably too cold.
Freezer should be 0 to 10 degrees. Ref 33 to 35

STOP PAYING FOR EXPENSIVE WATER FILTERS FOR YOUR REF. DO THIS====

WATER SPLASHING IN FREEZER AT ICEMAKER
THE FILL TUBE IN BACK OF REFRIGERATOR CAN SLIP
AGAINST THE FILL RESERVOIR CAUSING A PARTIAL BLOCKAGE
OR BECOME CLOGGED WITH ICE.
REMOVE THE ICEMAKER AND INSPECT THE FILL TUBE.
RUN WATER IN TUBE TO ELININATE BLOCKAGE AND CHECK
TEMP IN FREEZER. IF TEMP IS BELOW 0 DEGREES, THATS
OVERKILL AND USUALLY A WASTE OF ELECTRICITY TO KEEP IT THAT COLD, NOT TO MENTION THE FILL TUBE FREEZING UP

To get proper cool, keep the tips as follows:
1. Check air filter is cleaned. 2. Check indoor coil is cleaned. 3. Checkindoor blower motor is working. 4. Keep in cool mode. 5. Set temp minimum 3degrees less than room temp.6.Check compressor is working with correctpressure.
Thanks. Helpful?

Click start control panel,display,appearance color scheme you can change your colour scheme there also you can change other settings
settings you can make adjustments for more or less pixels or from the drop down list pick the appropriate level of color range

hope this helps

BUT FIRST: Check the ATR SENSOR, left from the developing rotor you have an "rail" with atr sensor - vacume it!!!!! Vacum all dev units, and copier

Have you tried updating the firmware and making sure the inter-key delay for the device that you use to change channels is set to 0?

Yes, the highest number would be the highest level of cooling. Normally you would set the controls to mid-range and adjust from that point to your satisfaction.

This sudden changes in brightness are caused by the change in voltage inside the tv,not in the outlet in the wall but inside the set,The changes are an indication something is going wrong and it needs to be corrected,the set does have a brightness limiter but it only works when the set wants to get brighter than normal,You need the assitance of a servicer to correct this problem.
