LG LCD TV Standby/Power light keeps blinking red

I have an LG LCD TV (model number 26LXD). Now when the unit is off (or standby) the led on the front of the tv is a steady red. On power up it flashes green and then stays green. I just came home from a short vacation to find the led flashing red (non stop) and I cannot power up the unit. I tried unplugging it and let it set for a few minutes, nothing. I tried a different plug, wall socket to no avail. Now there was a fan running constantly in the unit even after power down (had been doing that for some 8 months) now that fan is not running. Anyway, could it be that, that fan burned out and has caused the unit to not power up? Or is it something else? and what does the flashing red light mean? Thanks for any and all help.

Could be your Ballast Board that fires up lamp or Fan is bad that cools Lamp there is also a Fan mounted up under Light Engine if it stops running set will not come on. CK Fan Behind lamp first if it is OK then replace Ballast Go to E-Bay for Best Deal on that part .

LG will sell you a new lamp. It may resolve the problem but just as likely it's the contacts where the lamp unit plugs to the TV. There's a few types of connectors. The early ones are dodgy and cause the problem you describe. A faulty lamp can also cause it though.

This is vcaused by a relay similar to a fluro/ neon light starter switch. This part has failed so it cannot get syncronization You will neede to have a serviceman replace this part.

Hi richgpilot,
May I know how many blinks does the led light before it goes to standby mode. It will help diagnose where the exact fault came from.

TV turns itself off, then on automaticlly


The fan should run for a few minutes after shut off to cool the lamp down.

If I read and understand correctly somewhere in the cycle you are getting 5 red blinks? that is an error code........

Either you or I can Google the model number of the set with 5 blinks.....or visit the Sony site to see what it means.....

I have a Sony KDS-R50XBR1 that has no picture. When I turn on the TV, the green Power/Standby LED light blinks for about 30 seconds, then turns red and blinks five times. The Power/Standby LED repeats...


  • 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 A2 slightly.

Sony wega kdf42we655 power led blinking red


If lamp light is on at tv front then replace lamp as existing lamp sounds dead/ broken.
Lamp replacement procedure would be written in user manual of tv.
And if lamp light is not on but standby light is blinking then let me know how many times it is blinking to find out problem cause as standby light blinking is an error code.

Tv wont power up Standby light keeps flashing.


First step in any Sony LCD projector repair is bulb or lamp replacement. Fixes 95% of problems.

Taking apart and trying to measure things without a known good bulb is a waste of time and effort.

My sony 50" wega just quit. No picture , no sound , no nothing ?


Hi,
If you see standby red light blinking on Tv front with 3 seconds interval then count its blinks from pause to pause and let me know, its an error code.
And if TV does not even show standby light then check fuse in power supply that would be blew off for some reason, replace it.
Still problem? let me know with exact model number of your Sony TV.
Thanks.

Sony 50 Wega LCD flashing red light


Hi

How many times is the red light flashing? The number of times the red led blinks means---


  • 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.
  • No blinks(Unit is dead) - Problem in the standby power section. Might check fuse, R607, Q601, IC601, R612 and VDR601 (should show open).
Please do rate this solution as FixYa and revert for further assistance.

Thanks

The STANDBY light is flashing on the television and there is no picture or sound. Solution
sp.gif sp.gif 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.
