Sanyo Service Tip
SYMPTOM:
If the power LED on front of the TV is turning ON for 10-20 seconds, OFF for
1-2 second and keeps repeating, the problem is most likely IC5750A. Affected models are
the 2009 & 2010 TVs (LCD and Plasma) listed.
IC5750A is located under the large shield. IC 5750A is a 48 pin NAND FLASH IC with
easy access for replacement. This will fix +80% of the boards with the symptom below.
