TV on Standby

Its power supply I will tell you how to fix you need to get few things first

that is standby mode! maybe you have defective power supply in oscillation circuit! at hot side..

when in stand-by mode then red light's blinking. Try to turn it on not from remote but by pushing a button on the set.

Two blinks - B+ over current protection (OCP), unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits. Check this link to get more details about Sony Blinking codes.

Usually Sony and LG Blinking Codes are the same. Here is what I have.

• Unit is dead, No blinks - Problem in the standby power section. Might check fuse,
  
• Continuous blink once a second, no pausing - No reply from the jungle IC301 (data bus is busy, shorted to ground, or held high), IK video path is defective.
  
• One blink - not used for the self-diagnosis
  
• Two blinks - B+ over current protection (OCP), unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits.
  
• Three blinks - B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit,
• Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted.
  
• Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. In addition, unit could be in IK blanking, try turning up screen slightly.
  
• Six blinks - No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately.
  
• Seven blinks - High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.
  

• Eight blinks - Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code.

• Nine blinks - Panel Module Error or Thermal Error. If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing Make sure the regulator is -12 or -13 (negitive).

• Ten blinks - Check Q8014 and Q8013 for shorts, leakage, or bad solder connections on the " D" board. If the transistors are bad, check R8051 and IC8005, also on the "D" board.

The Sky+ remote should automatically default to Sony TV's. Leave the batteries out for a few minutes and try again. The Code for Sony is 0000.
Or try this :-

With TV and sky box on.
Press the 'TV' button on the remote.
Hold down the 'select' and the 'red' button (of the four coloured buttons) together, until the red light on the remote blinks twice. (takes 2 seconds)
Press the 'TV' button again.
Now enter four zeros, the red light on the remote should blink twice.
Press the 'standby' button (top right).
If the TV turns off, then press 'select' and the light should blink twice again, job done.

If the TV does not turn off then press 'TV' followed by 'standby' again.
Alternate pressing 'TV' 'Standby' until the TV turns off.
When it does, finish by pressing 'Select.
Check the red light on the remote, if it blinks 3 times, then it has run out of options for 0000.

4 blinks is bad backlight inverter. Download the service manual here:

Depends on how many times it blinks,just count the blinks Example: if it blink 2 times then pauses and blink 5 times then the code would be 25 and so on

Once you have this code,please post it.

Hi, this is an issue with a sensor on the power module. To fix it you must replace that part.

The blinks can tell you the problem , is it 4 blinks that could be 3 different ics IC1509 Q1505 or IC502
