    The TV will not turn on. The light blinks 9 times and no picture. We bought this TV on December 3rd, 2005 and it quit working on December 18th, 2007. Any suggestions on how we can fix this? The warranty just ran out right before the TV stopped working. There seems to be quite a few TV's with the very same problem and pretty much same time span, just after the warranty runs out.

According to all of the local repair shops, 9 blinks on the stand by light means that the power supply is shot. eand and every one told me that the set had to be taken to a service center for repair, since the power supply is in a board, not seperate. cost around my area is between 50 and 150 for the parts, labor from 100 to 200.

My view is never buy a sony again! 90% of the service shops will not touch sony, saying thay cannot be authorized by sony unless they pay sony for the certificate.

    Just an update, sent my television out to a repair shop. $200.00 is the cost (parts, labor, pick up and delivery). Thought price is worth it, seeing as tv was just purchased 2 years, 1 month ago. The thing that sucked was that the warrenty expired november 1st of this year, and it died on november 26th! Nobody would stand behind warrenty, or anything. Thought repair cost is still cheaper than purchasing a new unit.

    Still say, dont buy sony tv's again!

I have a Toshiba dvr620ku. It won't turn on correctly. The power light flashes along with the vcr-dvd lights. These just keep flashing.

Those 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.
If blinks continue without any pause, the main board is faulty./

is the voltage selector set to the

correct voltage?

I have a denon DRA-397 receiver and when I try to bring it out of standby, it attempts to restart then returns to standby after the tuner starts up. The standby button has a flashing red ring rather

When the power indicator is blinking red, there are a few possible issues. 1) The unit has overheated internally due to insufficient air flow around the unit. Let it cool down and then make sure that you have it in a well-ventilated area. (If you keep your home theater devices in a "closet", make sure that you have good air flow so that the heat from all the devices doesn't build up.)

2) The speaker wire cores are touching each other or the back of the unit. The DRA-397 will shut itself off if it detects a short of the speaker wires. Check the connections and make sure that the wires are not touching where they shouldn't.

3) An internal short or fault has been detected. In this case, contact Denon for repair.

I hope this helps.

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.

Standby light is flashing rapidly and I cannot turn on

In some cases, the STANDBY indicator may blink slowly, twice per second. In this case, turn off the unit, unplug the power cord, and check the following points.

Make sure the speaker cables are not reversed and connected to the wrong sides (+ and -) on the unit.

Make sure the speaker cables connected to the unit are not shorted. (Check both the unit end and the speaker end.)

Make sure the volume does not exceed the level that the unit is capable of producing.

When using the unit in a rack or other enclosed space, heat may build up inside the unit and cause a fire. When installing the unit, be sure to leave suffi cient space between the top, back and both sides of the unit and walls or other AV components to prevent the internal temperature from rising.

After checking these points, plug in the power cord and use the remote controller to turn on the unit. Turn down the volume before resuming playback. Confirm that there are no problems with the speaker connections and playback performance.

If this symptom recurs, request service at your nearest service center.

In rare instances, the unit may enter standby mode and the STANDBY indicator may blink rapidly, 8 times per second. In this case, unplug the power cord and request service at your nearest service center.

Bulb Reset issue

I had the same problem and called Sony, they just said to keep trying what the manual says to do, but make sure the unit is in standby mode. I tried in powered mode and in standby mode many times and it did not work. Then I tried again the next day when the unit had been in standby mode for an extended time period. I hit the four buttons like the manual said, all four in quick succession. I also tried the four buttons in many different sequences from what the manual said. When I powered back up the lamp timer was set to zero, finally! I think having the unit in standby for an extended time was the key. The Sony rep really emphasized the need for the unit to be in standby.
