The standby keeps flashing but the power doesn't turn on

I know power is getting to the unit but doesn't turn on.  I'm not sure how to dismatle the set but am willing if it will help.  The set was made in august of 2004?  any help would be great

TV shut off or no apparant reason. When I try to turn it on, you can here it trying 3 or 4 times but not actually coming on. Just a clicking from the back.

Is it a Sony?.That is usually caused by one of the two switching transistors.They are a matching pair.Test your HOT and those transistors.I'll bet one is bad. Let me know. - edcarson

Why my Sony Wega tv standby light blinks 10 times?


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/

The TV was working, and then randomly just shut off and won't come back on. It still makes the click noise when i turn it on, but only once instead of two. The standby light keeps flashing four times....


Hello melanie Hi, in my experience as a TV technician, that would usually be a shorted part, the horizontal output transistor, that part powers the HIGH Voltage section. Very Lethal, the power supply detects this bad part which in turn makes the unit go in standby so as not to damage the TV much further. mMy advice is go seek a tv tech to repair the part.

I have a flashing stand-by timer with a green screen. The stand-by timer doesn't flash all the time so i get a picture when it's not flashing. Is there anything i can do to rectify the problem or do i need...


If you can let me know how many times the licht flashes, I can tell you roughly where the fault lies. If it flashes in groups of 5, then it has a tube tracking problem possibly due to a weak tube.
Here is a list for you to decide what to do;

  • Unit is dead, No blinks - Problem in the standby power section. Might check fuse, R607, Q601, IC601, R612 and VDR601 (should show open).

  • 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, check T603 and R672.

  • Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505

  • 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. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. 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. Check C515 & 516 and the jungle IC, IC206.

  • 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. Check IC406 audio amp, PS401, and 402. On some projection models of Sony TV sets, this code means that T8005 (flyback transformer), or the associative components in the high voltage circuits are defective on the D board.



  • Nine blinks - Replace D 6116 and D 6301 on the "G" board, do not resolder as this will fix the problem temporary. Or Panel Module Error or Thermal Error. If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing, then change the switching regulator on the "G" board or check connections. 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.
Hope that is useful.

No picture or sound, standby led flashes 11 times when first turned on after AC plug has been removed and reinserted into the AC outlet. Every attempt to turn on after the initial attempt yields 6 flashes...


It seems that your unit has some sort of PSU fault, or a problem that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur. The flashing LED is justa coincidence I would think.
You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done.

Doesn't power up. Red standby light flashes.


How many times does it flash?

Odds are the A board components. Let me know how many times the stand-by light flashes, and I'll tell you want the fault might be.

TV turns off by itself after being on for 60 seconds


Led blinking Three times means 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, check T603 and R672.
Hope this helps.
