Sony bravia 32ex320 red led blinking 2times .what can I do


2X Blink - Main Power Error
A loss of REG12V from the power supply triggers this protect event. The usual cause is a failure of the main switching supply. In some instances, excessive loading on the secondary supply lines can cause the switching regulator to stop, or fail again, if a replacement board is installed. I would advise that you replace the main board. I hope this helps.

42PFL5332D/37 does not turn on red light flashes 6 times.


Don't have a "solution" yet, but found this table that decodes the blinks:

Error Code Table


0 = No error
1 = X-ray protection, E/W protection, and/or Vertical protection active
2 = High beam current protection active
3 = Reserved
4 = +5V protection active
5 = Signal Processor (IC 7150) register corrupted
6 = Signal Processor (IC 7150) error
7 = Total failure
8 = Internal RAM error (Microprocessor IC 7000)
10 = NV memory (IC7088) addressing error
11 = NV memory (IC7088) size error
12 = Histogram (YUV) (IC 7770) error
14 = Sound processor I²C error (TDA9855)
16 = Main Tuner I²C error (IC 1125)
17 = PIP Processor I²C error (IC 7350)
18 = PIP Tuner I²C error (IC 1127)

I, too, have the 6 blinks of a red light. I found another person online that suggested that perhaps the power cord was "defective" as it's a common issue. I replaced the power cord with one from an old computer (they're the same cord) and it seems to be OK now. That's all I can offer you at this time.

65 INCH PROJECTION SCREEN IS SUPER BRIGHT


super bright is due to failure in video section. 1 video supply might be absent. 2 g2 voltage mighi be high gue to some part defective at ground side. 3 chroma or jungle ic not getting supply or defective. 4 luminance section defective. BUT AS you are also saying that it came once after hitting on top so there is also possibility of loose contact also. good luck.

This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source) 1. Self-diagnosis error 2-3 indicating deflection failure. Check for shorted or leaky Q5A37 part # 260P818050 located on PCB-Main. If found defective replace only the transistor instead of the Main PCB.
