Then removed the batteries in the remote control, the fault still exists, thus excluding the possibility of remote control button problem. Ask the user remote control for his family has two SAA3010T chips, after the two remote control button is pressed at the same time, this symptom occurs. From this analysis, is the microprocessor (PCA84C4841/177P) program appeared disorganized failure.
Adjustment method is as follows: two at a television remote control the remote control window, a remote control, press the mode selection key, a remote control, simultaneously press programme + and-keys, two remote controls to press these three keys simultaneously until brightness symbol is stationary, then the minimum brightness of the TV. Then release the program key is still used two simulation function and program + keys of the remote control, the brightness in normal status. Using the same method, adjusted the color, contrast, volume, etc simulation program. Typically repeat the above adjustment method three to five times to return to normal.
