    Dear Nuwan chinth, thanks for your answer.
    This is helpful, but it is so global answer : )
    Could you narrow the problem ?
    If the problem on the power supply or power amp, which the component was broke ?
    Any body,s suggestion are welcome




  • patno72 Jan 15, 2009

    I have checked the connection , and no problem.
    When problem occured , I hear sound like mousquito sing at power supply part.
    But when the unit working properly, the sound (mousquito sing) is mute
    is it problem problem caused the condesator or ic or transistor or zener diode ?

    Thanks



  • patno72 Jan 15, 2009

    Dear Nuwan, Thanks for your suggestion.
    Where is the position of the relay, on power supply board or on Power amp board ?

    Thanks


  • patno72 Jan 15, 2009

    Thanks for your fast respone.
    A little question : on the manual guide said, if we close the ventilasi of the fan, the standby led will blinking.
    What is the sensor on the unit to detect it ? Is this temp sensor or light sensor or other ?





  • patno72 Jan 16, 2009

    I'll try to send the manual to you.
    I will explore the unit to check the relay, and inform you for the result
    Thx

I have an Alba 32947HD TV. It was totally dead. The PSU board was faulty. I have replaced the PSU & now the standby light flashes - sometimes slowly, sometimes faster. There is no sound & no pictur


Those 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.

If blinks continue without any pause, the main board is faulty.

Error code by led indicator samsung SP67L6HX1X


<img src="mas_baz.jpg" /><br />There are three LED indicators. LAMP, TIMER, STANDBY/TEMP. Each Led or combination leds indicated problem.<br /> <ul> <li>LAMP blinking : The picture will automatically appear in about 15 seconds.</li> <li>TIMER and STANDBY/TEMP blinking : A cooling fan inside the set is not operating normally.</li> <li>LAMP and STANDBY/TEMP blinking : Lamp cover on the rear of the set is not properly shut.</li> <li>STANDBY/TEMP blinking : Check if the ventilation hole on the rear of the set is blocked, because if the inner temperature is too high, the power will shut off.</li> <li>All LED blinking : Lamp may be defective.<br /></li></ul>It takes about 30 seconds for the TV to warm up, so normal brightness may not appear immediately. The TV has a fan to keep the inside lamp from overheating. You'll occasionally hear it working.<br /><br /><br />

My TV lost the picture. Pushing on the indicates no back lighting. The Standby LED was giving a single and intermittent flash but now nothing. All PS voltages are present.

Why won't the tv come on, just get intermittent flashing red standby light?


Most likely it's a capacitor fault.

Google "Capacitor bulge" and then search Youtube for your make and model to see if anyone has done an instructional video. You'll need to be comfortable dismantling the unit and be able to use a soldering iron. If this isn't you then take it to a repair shop.

I have LG 32LC46-ZC TV. It suddenly stopped working, no picture, no sound. The LED blinks 5 times after turning on, but nothing else. Any suggestions?


These blinks (flashes) are fault indication. By the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside the TV. Count the blinks occur at one time switch ON, carefully. Do it once again, and make sure about the number of blinks. If the flashes are continious, non-stop, the main system control IC should be suspected. If you wish to get more details, check the site linked here. It has blinking codes detail to many brand TVs. Pull up older posts. Check the site in 'Mosaic' view. It will make search easy. http://electronicshelponline.blogspot.com/

SUBJECT: Counter measure for Intermittently 5 times standby LED blinking
SYMPTOM: Customer may report that intermittently after AC OFF/ ON (or Deep Standby/ ON), TV will shut down with LED blinking 5 times. If set is placed in Standby, then On, symptom will re occur. If AC is removed, set will work normally when AC restored
CAUSE: Timing mismatch of I2C communication causes interrupt signal inside TV. This causes TV to shut down with error 'Standby led flashes 5 times'

SOLUTION: This is a user correctable issue -
Where possible, please refer customer to Sony Website -(or ) and search for relevant model to download correct update. If the unit is in Workshop, please perform update as per Instructions.

TV won't turn on and standby light blinks 9 times... what can I do to fix this? Thanks, David


Nine blinks - Indication of shorted/leaky diodes - D6116 and D6301 on the "G" board. Panel Module Error or Thermal Error. Unless you are technically experienced, this can only be repaired by an authorised service centre. Obtain a quote for this, the parts are inexpensive, but labour costs might not be.

If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing, then change the switching IC regulator on the "G" board or check connections. Make sure the regulator is -12V or -13V (negative rail).

If the repair is done by an approved workshop, they will clear the error codes (standby LED blinks) as part of their 'soak-testing' and it should reset the TV back to factory condition. Remember to ask about what work was done and if the errors have been cleared/reset before you pay their bill.

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
