There could be a problem with the picture tube itself, or a fault in the High Voltage protection circuit, or a beam current overload fault. These arfe the type of repairs thats going to require the know how and trouble shooring skills of a trained tech. It depends on the age of the set and how much your willing to invest into the set to see if its worth it or not. Good Luck

My Sony Bravia TV - Model #: kdl-52z5100 no longer powers on. There's a red light that blinks twice whenever I attempt to power it on. Please help


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.

Sony Bravia KDL-52XBR9 wont turn back on red led flashes unless I uplug and plug back in. Did firmware upgrade to newest aa0143pn, still happening.


There is a error in TV.Count how many times blinking the red light.

  • 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 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. GA_googleCreateDomIframe('google_ads_div_TL-IMU-Article' ,'TL-IMU-Article');

  • 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" boards

How do i key in code for digibox


TO PROGRAM THE remote USING THE 3 DIGIT CODE:
1. Turn on the TV receiver
2. Press TV on the Sky Remote Control
3. Hold down SELECT and the RED buttons together for approximately two seconds, until the RED LED on the Sky remote blinks twice.
4. Enter three digit code from list for the receiver (early versions now flash twice).
5. Press select to enter code structure (the LED will flash twice if a valid code has been entered).
6. Now press the STDBY button and test other functions.
Repeat if necessary until a code is found that works most common functions.
TO PROGRAM THE remote USING THE 4 DIGIT CODE:
1. Turn your TV on.
2. Press tv on your Sky remote control.
3. Hold down select and the red button together for about two seconds, until the red light on the Sky remote control blinks twice.
4. Press tv on your Sky remote control again.
5. Key in the four digit code for your brand of TV. The light on the Sky remote control blinks twice. If the light blinks once only, recheck the code for your brand of TV and start again at Step 1.
6. Press the standby button on your Sky remote control. If your TV switches off, press select. The light on the Sky remote control blinks twice (code stored). If your TV does not switch off, press tv, then press the standby button. Repeat this (press tv, then standby) until your TV turns off, then press select (stores code).
If at this point the LED on the Sky remote control blinks three times then all possible codes for that make of receiver have been checked. Repeat from step one, ensuring that you enter the correct manufacturer code.
At the end of the sequence, if you see the TV Guide screen, the remote control setup process is complete. If you did not see the TV Guide screen, you must now complete the following steps.
8. Press tv on your Sky remote control.
9. Hold down select and the green button together for about two seconds, until the red light on the Sky remote control blinks twice.
10. Key in the number of the channel on your TV that you use for watching satellite TV.
11. Press select on your Sky remote control. The red light blinks twice. The remote control setup process is complete.
If after trying this, you still have problems, call your broadcaster's help desk. For your broadcaster's help desk number, select the Telephone Numbers option from the Services screen.

TV won't turn on, red light flashes twice


Fortunately, Sony, of all manufacturers, has built in a diagnostic tool to help you decide what the problem is.

Below is a text on these codes. This is not your model, but the basic diagnosis remains the same. You can count the number of blinks and then look up the problem and solution below:

-----------------
Sony Blinking Codes
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 the 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 eight blinks (depending on the fault) about a third of a second apart, then pauses for 3 seconds, then the two to eight 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 and there are 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 As Discussed Above---

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 Vert. Deflection (V STOP), Screen goes to a single
horizontal line then the video signal muted. Check IC1509, Q1505
FIVE Blinks---AKB circuit (AKB), 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. Also unit be in IK blanking,
try turning up screen slightly.
SIX Blinks---No Horizontal (H STOP), no raster, goes to the blinking selfdiagnosis
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.
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, Vol 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 problem names is 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.
So, 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
4 times....This would tell you that you have no vertical and that 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, but it's a little better than a poke in the eye with a sharp
stick.
IMPORTANT: after you repair the unit, PLEASE clear the values on this diagnostic screen. These codes do not reset themselves after the fault is 0 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 ) then press 8 and Enter, which of course returns
everything to the factory preset condition.

----------------

As a general rule, the blinking standby light means serious problems and you would be better off getting a technician involved.

This set is a very expensive one and it has some life left in it. Further it is a Sony, so you will be wise to get it fixed.

After studying the blinking codes, let me know if you have any further questions.

Have a great Holiday Season,
Cleggsan
