Hello; You probably have a CRT type set. Something has magnetized your CRT/Picture tube. The set has a built in degaussing system that will only work when you turn on the set when it is COLD ONLY. If after several cycles of turning on the COLD set and the green color hasn't gone, the circuit in the set for doing this has failed, OR you have the set near strong magnets, such as speakers. PUT ALL speakers at least 4 feet from the set and go through these off on COLD cycles. The deflection yoke on the picture tube could have moved due to Sony using crappy adhesives to hold the yoke positioning wedges in place. I am so glad to be done with Sony!!!!! John

The standby light shouldbe blinking is a pattern of a count followed by a pause then the count again repeatedly. If you can post that count here, we can use that to indicate the circiut in which the problem exists. That will determine the probable cost to repair.

Thanks

This tv have two power ICS left side of the FBT-The Flyback Transformer.The big black block of plastic with a red wire with a cap hook to a CRT(tv tube).Replaced those 2 power ICS,tv will solved this LED power light flashing,tv will have stable power again,tv will work.

trouble in power supply try to look swollen capacitor or leaky transistor.

Hi


Thanks for using FixYa. If its flashing continuously and you are unable to count the no# of blinks then the issue is with the bulb going bad and should be replaced. Please do accept the solution if the issue is resolved or post a comment for further assistance.

phillips has the same problem but if your tv actually turns on it could be a short or just a fuse sonys a better tv than phillips should be an easy fix call a repir guy going price for that problem is 75.00 dont pay any more than that. the economy is bad everyone needs the work be smart. make sure if you say yes to the work that the repair guy will waive the consultaion cost of usually 35 to 75 dollars, if you chose to have the work done.

Hi

Thanks for using FixYa. It you are away for a long period then turn it off to avoid any damage to the TV. Resolder the flyback transformer (FBT) as this transfer the power to the TV. A bad switch, power supply failure or a blown fuse as we know fuses blow due to high current event, possibly a shorted component on one of the low voltage rails. The shutdown circuit could be activated. The problem most likely will be that a component has become thermally sensitive or some capacitors that have become puffy or bloated and needs to be replaced. From what you have described it seems the issue is with the power board or the main board we’ll need to check few things. When you open the unit up; take a look at the power board-the board where, the power cords/plugs goes into. You might see some filter capacitors a little bulged up in the top-If this is the case-this is your defective part(you can try to replace them-but some soldering equipment is needed). If not, then probably the main board has gone bad. This is the other board-where all the inputs are going into. Also check the Backlight Inverter Board if the sound is coming fine from the TV however as it’s shutting off so it should be either the power board or the main board. All this is only recommended if you have electrical expertise and know how to solder/re-solder components.

Please do rate the solution if the issue is resolved or else revert for further assistance.

Hi

Thanks for using FixYa. Blinking Red Standby light indicates a issue with the internal circuitry of the TV, as you have not mentioned the no. of blinks so please check this:


  • 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 go to the standby mode then display 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 go to the standby mode then display 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 (fly-back 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 (negative).
  • 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.

This is from the Sony support site...

URL to page

"The STANDBY light will flash if an issue is detected within the television. This can sometimes be resolved by simply following the steps below to reset the television.
  1. Turn off the television. IMPORTANT: For a projection television that uses an internal lamp, wait 5 minutes after turning off the television to allow the lamp to cool before continuing with the following steps.
  2. Unplug the television power cord from the electrical outlet.
  3. Let the television remain without power for 60 seconds.
  4. Plug the power cord back into the electrical outlet. NOTE: If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
  5. Turn on the television.
If the issue is still unresolved after following all of the troubleshooting steps, service may be required. Please note the number of times the STANDBY light flashes and relay that information to the service center."

Turn it off u leave on to long ur CRT Tube will dies soner.Resolder the FBT,the flyback transformer, the big block of plastic with a red wire with a cap hook to the and the transistor beside it.This transformer is the HV to the CRT to get power.

Sony FD... | Answered on Jan 15, 2010


Good day.

try to check for loose contacts along the power supply section then resolder. Also, check for shorted vertical IC.

if its an LCD or plasma tv, it sounds like an invertor problem. (the invertors run the backlights to light up the screen). I would advise getting this repaired sooner rather than later, because if the invertor fails completely, it may damage the backlights and render the TV useless. if it is a CRT (tube) TV, then its possibly a bad solder joint near the HT area of the main board.

I'm having the same problem. My stand-by light blinks 3 times though. The tv clicks as if it is going to turn on, but it never does. Is there a simple solution to this problem?

Sony FD... | Answered on Sep 18, 2009


Turning your tv off did not cause this issue, so don't blame yourself for that. A 6 or 7 blink shutdown is because one of the two switch mode power supply control ic's have failed. the part number on them is mcz3001. They are located on the "D" baord, i don't recommend replacing this yourself because even with a tv unplugged from the wall high voltages still exist in the set.

A repairman may preform one of the two following things, he may change the whole D board or he may replace the individual components. The repair will cost around $200 if they replace the components, and if they replace the board it will cost more.

Sony FD... | Answered on Sep 05, 2009


This is often caused by a faulty transistor, they breakdown over a period of time and can continue to work by shcok treatment ( like unplugging etc) but eventually collapse. The srvice center for your Sony may repair it or replace the whole board to the video section. Its a Bravia so expect a pretty expensive callout, somewhat cheaper to take it to a technician in this case
