My dcb-p850z won't switch back on. flashing red lights

SOURCE: tv wom't switch on

Replace capacitors on power board.

SOURCE: my panasonic th-50px60u television turned itself

Tries tv unplug,replug it back like about an hour later for the tv to do it resetting itself back to the factory setting,tv might work again.If not still same problems.The tv 90-95% it is the board that call the tv power supply board is having a problems.That the board where the tv power a/c cord plug into it.U have all tools and know basic electronic and also can do basic soldering works too?Yes,take the tv aparts,check the tv power supply board carefully for dying and soon to be dead capacitors components parts.These capacitors components parts are alway bulges up or puffing up onto it tops.These dying and soon to be dead capacitors components parts are bulges or puffing ups on to it tops must have to be replaced will solved ur tv power unstable and flashing red light.Or try website like Ebay.com to buy a whole new refurbish tv power supply board for the replacement.

Does the tv make a clicking noise like its trying to turn on before the tv goes into standby and the LED starts flashing? I suspect this is due to a shorted component, most likely to be in the 5V(switching) line and just want to be a bit certain before we start testing the power supply.

SOURCE: My tv won't turn on. There is a red light

Replaced any capacitors on the power board that have domed tops.

SOURCE: TV won't turn on. flashes a series of 5 red lights instead of turning green

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.
