TV will not come on andthe red power light starts blinking in a short series of 6 blinks and a pause of approximately 2 or 3 seconds.
The TV will not come on, however, the red power light starts blinking in a short series of 6 blinks and a pause of approximately 2 or 3 seconds, and then repeats this pattern over and over. This has to be some type of code indicating what a technician should start looking at to repair the set. Does anyone know what this code means? This set is just over a year old and I would like to repair it.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

green led means tv powered on and status ok.
Red blinking light almost always means defect, overcurrent or overload.
6 blinks for Sony lcd flat tv means trouble in backlight circuit, or backlight inverter (backlight illumination or lighting makes your tv screen visible).
common problems in the inverter circuit, which drives the backlight, or shorted drivers, or short-circuit transformers or open circuits. You should find the problem in the inverter circuit, or in the power supply board or in the main board.
Also look for bad capacitors (electrolytic caps) which are bulged and swollen on top.
Decoupling plugs from printed circuit boards can help you in finding the problem board by elimination method.
If you power up the set after unplugging certain plugs on f.e. the inverter board , this could result in getting a green power led and concluding that this board is faulty.

"Timeslide" or "Flipcard" option, which can be selected
from the drop down box menu by the [Sidebar] tag, at the top left corner
of the display window. It will make
search easy. There are more than 1200 posts to different brand TVs now. Pull up
older posts there. Blinking codes to so many brand TVs are described in detail here.
wait for the light to go out then press power. Then if it doesnt power up hold the menu and the Device/input buttons on the set both in together for 5 seconds the light will blink a series of blinks pause briefly then blink another number of blinks then pause then it will repeat the same two digit blink sequence a few times . Let me know the two digit blink sequence.
Usually Sony and LG Blinking Codes are the same. Here is what I have.
Unit is dead, No blinks - Problem in the standby power section. Might check fuse,
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,
Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted.
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. 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.
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.
Nine blinks - Panel Module Error or Thermal Error. If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing 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.
Its 2 times blink error code that shows +B volt supply (+135 volts) is shorted, most probably horizontal output transistor is shorted, replace it. If you are good in soldering parts in circuit board then take out horizontal transistor, check it, found shorted then replace it with same number.
Horizontal output Transistor Q502 number is 2SD2578 and available in Part Store for $10 Let me know for further query, if any. Thanks.
Please intimate exact model of your Sony TV and also mention how many times red light blinks as there would be pause of 3 seconds in blinks so count pause to pause and let me know to find out problem. How old is this TV and did you replaced its lamp? Thanks.
hello it sounds like a main board issue but try this number and explain exactly ur issues to them they may say they only give info on parts but trust me just keep working ur way up and ull get some answers 800-833-9626 pannys parts and service their service manuals are horrible and not very much info that is really valuable is included in their service manuals another way to make money imagine that.
ill keep researching ur problem let me know if u get anywhere
