Question about Sony Grand WEGA KF60XBR800 60" Rear Projection Television

1 Answer

Turns off turns on standby light flashes

The same others describe. I read your solution and wonder how much it will cost to have the horizontal sweep adjusted or the vertical power supply replaced. Thank you.

    Hello,

    Yes I have the same problem, after 2 minutes the Sony will turn off, if I do nothing it will eventually come on then off again and repeat the same thing. When it goes off and I turn the power off the power light will blink 5 times and will do this a few times then the set will shut off. The picture is as bright as usual when on and I can hear the fan running.

    Is it possible the light can be drawing too much current, or some kind of sensor for the fan that can be plugged?

I have a 55" sony


According to the manual (you can see it here) page 122 that describes 3 red flashing lights:

"The lamp cover is not attached securely. When you secure the lamp cover, the POWER / STANDBY light flashes in red and the LCD projection TV enters the standby mode (see page22)"

Page 22 says:

"... if the POWER / STANDBY light flashes continuously, this may indicate the display unit needs servicing..."


Most DLP displays make use of a "color wheel". These small motors spin at many thousands of RPM. They often begin to make scratching sounds when they are beginning to fail. Some manufacturers make it difficult to change yourself - and others make it pretty easy.

I hope this was at least a good starting point for you & good luck. Please rate my reply. Thank you.

Replaced bulb on sony KDF-42WE655, When power turns on then turns off with 3 flashs of red light continuouis?


SD Tech,
With your kind permission if I may provide info...
3 times red light blinking shows that lamp cover has not been fixed in its place securely after lamp replacement.
Make sure lamp cover, its the first plastic cover that was removed to replace lamp, is back in its position properly then turn On tv.
This plastic lamp cover engages safety micro switch inside tv cabinet.

I have a sony 64 inch not sure of the model but as we was watching a show the tv shut off and now the green light flashes for a few seconds and then turns to a flashing red light but the tv wont come on ....


Many of the later model Sony TV’s have a built in self-diagnosis function. If the timer/standby indicator is blinking, this could be an indication of a problem with the unit. The diagnostic blinking will occur automatically with no action required by you to engage it.
The timing of the blinking you see would be as follows: two to nine blinks, (depending on the fault), about a third of a second apart, then a pause for 3 seconds, then the two to nine blinks about a third of a second apart again.

Here is a list of the problems that might have occurred indicated by the number of blinks. The words in parentheses are those, which you will see for each of these faults on a diagnosis screen described later in this article.

  • 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.

  • GA_googleFillSlot("TL-IMU-Article")       Eight GA_googleFillSlot("TL-IMU-Article"); 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.

Intermittent problems? This is a great feature. You can also bring up these fault codes on-screen to see a list of the problem numbers with the abbreviation of the problem and the number of times this problem has occurred. This is slightly different than entering the service mode. To see the diagnostic screen, press the following buttons: Display, Channel, 5, volume Minus, ( not plus ) then Power. This brings up a screen with a list of the problems and number of times they have occurred. Each of the problems named, are abbreviated as, "OCP", "OVP", "V STOP", ETC. We have repeated them in parentheses in the text for the "Blinks" described above so you can correlate between the diagnostic screen and the blink codes.

Now that you know about these self-diagnostics, how do you use them? Say that you have a set with a black screen. You see that the LED is blinking four times. This would tell you that you have no vertical sweep, which is why the video is muted. If it was blinking 6 times, you would know that you have a horizontal fault. It's not a sure cure..

IMPORTANT: After you repair the unit, you MUST clear the values on this diagnostic screen. These codes do not reset themselves after the fault is corrected, so if you don't clear them, you'll be seeing "old" fault codes the next time you enter this screen. Clearing is done by going into the service mode (display, channel, 5, volume plus, then power ). Press 8 and Enter, which returns everything to the factory preset condition.

I have a Trinitron KV-40XBR800. Won't come on.


the indicator lamp flashes a determined amount of times then there is a pause, then lights the same amount of times again, by what you describe there is a power supply or a deflection circuit problem.

Flashing red light


The jungle chip is the main IC processor. It is very complicated and has hundreds of circuits surrounding its complexity.

Six blinks is a diagnostic code for loss of horizontal sweep. Thus there is no raster and no high voltage.

Cure requires a look at the jungle chip and the horizontal synch signal to see where it got lost. Cost of repair is not so much unless the jungle chip must be replaced which is rare, but very expensive.

A good repair place can fix it quickly and under $100 so beware of who works on it.

Standby light blinking


Set has problem in one of the circuits, possibly sweep or video. All modern sets have a diagnostic mode when turned on, such as flashing standby LED. If there is a malfunction, such as a voltage loss or short in one of the circuit boards, the power supply will prevent further damage or fire hazard. Take unit to pro/tech for repair.

The power supply or sweep power supply blew up, or the Horizontal/high voltage circuit went bad. If you have no tV repair experience, call in a pro to assist you in this repair. Good Luck

The unit powers on and off.


There is a short somewhere in the sweep Horizontal, or vertical, or the sweep power supply has a fault. not really a job for the consumer , unless you know about solid state electronics.
