Trouble Diagnosis
8-2. Typical Symptoms of PCBs problem or bad connection
A. Symptom of initial latch up
- Define initial latch up : When turn on the power, both LEDs light up red and
TV is not working.
- Repairing method : This is typical symptom when ROM(ICU3) is incorrectly connected
at socket. So if you find this symptom, you must try to that ROM(ICU3) and socket
have correct contact.
- As this method, TV set is not repaired, replace MAIN PCB.
B. Symptom of No image when LED and Back Light are working.
- Define No image : LED and BACK LIGHT of panel are correctly working but any image
does not display.
- Repairing method : This is typical symptom when LVDS cable incorrectly connects.
So if you find this symptom, check LVDS connection.
- As this method, TV set is not repaired, replace Main or Sub PCB.
C. Representative Symptom caused by bad Connection between PCBs
=> Note: Dust or extraneous material may cause bad connections. Most of the time,
applying soft brush, AIR FRESHIER, or breath to clean dust or extraneous
materials can solve it. And then reassemble the Connector.
