Hi, The number of flashes (on/off) is indicative of a code. The code represents a particular problem. For example on some versions, 3 blinks indicate diagnostic mode where the builtin protection has kicked in (very likely a powersupply problem), 5 blinks indicates a video controller fault (possibly picture tube drives). Unfortunately this require the services of a qualified TV professional very familiar with Sony WEGA. In some cases this type of errors can be corrected by a hard reset, while others still would require board replacement (expensive) or hopefully component level repair. Good luck and post back should you need further information. kind regards.

Hi again,
By hard reset, you have to unplug the Sony from the mains for a couple of hours (about 5 hrs)

Check the power supply mainboard if there are inflated electrolytic capacitors, to replace them.

The flashing timer light blinks out a code, where it flashes some number of times, pauses, then repeats. The code indicates what fault is keeping the set from coming on. Unfortunately, all the codes tend to mean that there is some electronic problem with the TV. Unless you have some electronic servicing skills and the necessary equipment to troubleshoot the problem, you'll need to have set checked by a professional. For any code there can be many causes, so I can't offer any other advice.

This might be a good time to check sale prices on LCD sets. Let a technician check the set and give an estimate for the repair, then decide.

TV Won't turn on, Has flashing red light.

Flashes of standby light is fault indication. Count it and confirm the number of flashes occurs at one time switch ON. If you wish to get more details about these blinking codes to Toshiba sets, check this link. Pull up older posts there.

I have a Sony Bravia LCD tv an it won't turn on at all the standby light is not even there I've tried turning on an off and leaving unplugged for an hour still nothing.? Help,

You either have a problem with your power supply board or main board. I would start with having the power supply fuse checked as well as the power supply board!

Lcd tv light flashing but no picture or sound

If you removed power by turning off power itself to the set instead of turning it off by turning the set itself off---that is not a good thing to do.

When power is restored a surge can and likely hit the power supply in your set---time for a tech or shop to open it---I suspect they will find the standby or main power supply is damaged or now bad.

Sony HCD LX20i audio shelf sysyem won't turn on. Standby light flashing. Disc stuck in it.

Check the speaker wires for shorts, if okay! suspect the audio output ic's, the protection circuit won't come out of standby because there is a short.

TV won't turn on. flashes a series of 5 red lights instead of turning green

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.

Doesn't power up. Red standby light flashes.

How many times does it flash?

Odds are the A board components. Let me know how many times the stand-by light flashes, and I'll tell you want the fault might be.
