    Would the control board be the "D" board?

  • WSLuck Mar 17, 2008

    This problem is intermittent, as long as the TV is plugged and I attempt to turn it on it will not come on. If I unplug it for a period of time and plug it in before trying to turn it on, it will come on.

    Could the LOT give me an intermitent problem?

  • WSLuck Mar 18, 2008

    I agree 110%. Thats why I came to you guys with questions and acquired a service manual for the set. Thank you all for your input. I really do appreciate your help.

Sir this is not a big problem at all. its just a LOT problem.

this can be solved easily.

just remove the board.

if you look at the board then see if it having a large black colur component. this is called LOT- line out transformer. (tis is what johny mistyped as lvt i think)

this will have 4 to 5 pins i think. i dont remember exactly because i did this before few months. so forgot. cant recall exactly.

you will have to replace this component.


manner solved sir.

you will get fixed.

thank you sir

good luck

    well..what I've learned in working with TV's and high voltage electronics, is not to GUESS at what's going on. And, without the proper diagnostic equipment at hand, safely conducted with good prints and diagrams, makes for a potential disaster.

    I strongly recommend you get your hands on a service manual for this product.

Here's my suggestion , unhook all the external components to the TV and leave the TV unplugged for more than a few minutes (a day/overnight). The next day plug the TV into the wall outlet (not the powerstrip) without anything hooked up to it, and turn it on. See if it comes on. Sometimes unplugging for a few minutes/hours is not long enough for it to reset itself.

TV does not turn on. Stand By LED blinks 4 times and pauses and blinks 4 times again Tv will not turn on...when plugged in the red stand by light flashes 4 times...you can hear the tv turn on but a black...


On older Sony, sometimes a power surge causes the set to be in shut down mode. Try unplugging for 5 minutes and then plug in and try. This many times will fix.

Sony Vega Service Codes


KV-32HS510 and KV-27HS420, seven times blink error code shows problem in Horizontal deflection circuit.

There are many possibilities like dry solder joints, weak capacitors, Horizontal transistor short or flyback transformer fried etc.

If you have little experience of TV repair and good solder skills and have necessary tools to test / check defective parts, then you can make it. you also need to have related service manual to see board location, schematics and part numbers.

Stand by light blinks 6 times, wont power on


Here you find sony blinking codes

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.

Sony tv wont turn on, standby light just flashes


I had the same problem guys! This is what I did:

My T.V. wouldn't turn on. The standby light was flashing six times, then four, then seven...I called Sony and they told me to unplug it for a couple of minutes, then try it again...didn't work....BUT, I have found a solution:

Try unpluging your T.V. for 4 hours+, then turn it back on. Worked for me! It's called a "hard reset" by sony. I had my T.V. unplugged for the whole day though.
