    I have exactly the same problem - you can hear a relay trying to lock in but as the crackling sound starts you can hear it drop out again. This happens a couple of times before it stops trying to tuen on and the green light turns red.

    It does not happen every time, sometimes I am lucky and it is OK but you always hear the noise and the relays clicking.



    I have ordered a full service manual with circuit diagrams so will attack it if it fails totally - I will let you know what I find.

    I had exactly the same problem, at first intermittent then failed completely. Fault code red led on display flashing in bursts of six. On opening up LCD panel no obvious problem could be seen on the power board G1 but on closer inspection capacitors C6107 & C6108 looked slightly domed possibly blown. About one week later my tame electronics engineer (brother) came to have a look. He changed the two capacitors although not 100% sure they were the cause of the problem. On re-connection set fired up and operated normally, went through a few on/off cycles and all looked good so put set back together and worked fine until last night when would you effin believe it it played up again; started up at third time of asking. time for another strip down and further investigation.

The solution to this problem was the Relay RY6001 replacement. I was able to find a suitable part from CPC check out:-
http://cpc.farnell.com/schrack-components/rtb74005/relay-pcb-spco-5vdc/dp/SW02588
for the details. The part fitted Ok when one of the pins is cut off. You do not need this pin so it is OK.

I have a full set of fix it photos if anyone needs them. It took about 40 mins to strip, replace and re-biuld the TV - there are loads of screws to get at the PCB and then you have to put them all back!!

Thanks again to mgnut for all the info.

Hi, After thinking of buying a new LCD tv because my 4 year old sony kdl-l32mrx1 was having problems starting up, i decided to have a look on the internet to see if i could find out any information as to what was wrong, i found these solutions on FIXYA. Sometimes the set would come on first time but mostely it would take several attempts to get it to work, the screen would go into standby mode and the red led would flash six times, the problem was a relay as described, Part RTB74005 on the power board, i managed to get the part from CPC, cost £3.35. So after a couple of hours dismantling the back of the display unit and a bit of soldering to replace the faulty relay (i`m not a technitian, only i only have basic knowledge of electrics) i switched on the tv with fingers crossed, and the tv fired up first time!, tested it ten times to make sure and everything is ok it starts up first time every time now. Thanx very much to the guys who gave the info.

Well in my case the problem turned out to be a faulty relay. Component RY6001 on the G1 power board. If you would like to read the fault finding procedure carried out by my resident expert (brother) please take a look at:-  www.agoraquest.com/viewtopic.php?topic=34045&forum=34. Or just search the site using the model reference. Hope this will be of use, from once again a happy Sony owner!

Sounds like somthing is shorted (hence the crackeling sound) and the unit is going into error protection mode causing ot to go back in stand by. The most common problem is bad caps or shorted fets on the power supply. If your good with a meter, you should be able to open the back of the set and find the problem quickly. Or look at the back of the set when you power it on and see if you can find the arching.

Sony wega kdl-l32mrx1 10 yrs old. picture wont come on display standby light goes green then a crackling sound from the back of the tv, the standby light then goes red again, and flashes 6 times have


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. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience.

TV WONT COME ON AND THE LIGHT KEEPS FLASHIN RED AN GREEN ON THE STANDBY BUTTON


  1. If your Sony Wega will not turn on, the front green light blinks, you hear a faint whirring sound and the green light turns red and flashes, it probably means the lamp inside the set is no longer working. If you noticed the screen beginning to dim in the preceding days or weeks, this most likely is the cause.

  2. If the green light flashes and the picture comes on momentarily but then goes off, and the green button flashes until the set restarts, then the seal around the lamp mount is loose and needs to be refitted.

  3. If the picture on your Grand Wega cuts in and out and the green standby light flashes, both of the set's STKs need to be replaced. STKs are small chips on your television's circuit boards and are identifiable by their labels. The specific STKs used in your Grand Wega TV will be identifiable by the numbered labels on top of the STKs.

  4. When you plug in your Sony Wega and hear a loud popping sound, it's probably caused by a defect in the high-voltage circuit. Let the professionals take care of this one.

  5. If, after turning on your Sony Wega, you can hear your set but the screen is black, you most likely need to replace your projection lamp.

Most likely this is caused by a defective main board. Changing the main board will fix the issue about 95% of the time.

To be absolutely sure, the voltages need to be checked on the power supply. If they are not the values listed in the service manual, then you should replace the power supply instead (accounts for the other 5% of the time).

Usually resetting a device like that is done via it's On Screen Display (OSD). Maybe you need to contact Sony Tech support.

You can do this by clicking the below link:
