I have audio but no video,after 5 minutes the video comes on. After it is on it will blink off and on for a while.

You might try the following:

Clock Setting Procedure

1. Press and hold the time button until the hours blink.

2. Adjust the hours by turning the right side Tune / Audio control.

3. After the hours are adjusted, press the right side Tune / Audio control to set the minutes. The minutes will begin to blink.

4. Adjust the minutes using the right side Tune / Audio control.
5. To exit, press any button/knob or wait 5 seconds.


I hope that helps!

The problem is in the audio out stage in the receiver, but check speaker wires for shorts first, if okay! you will need a pro to assess repair cost.

The blinking red light is an error code. You need to count the blinks in order to find out what could be the issue.

1. Press and hold the time button until the hours blink.

2. Adjust the hours by turning the right side Tune /

Audio control.

3. After the hours are adjusted, press the right side Tune

/ Audio control to set the minutes. The minutes will

begin to blink.

4. Adjust the minutes using the right side Tune / Audio

control.
5. To exit, press any button/knob or wait 5 seconds.

Not sure but I think the radio needs to be off when you do this but don't quote me on that. I hope this helps you and good luck.

Bypass it.

Best video to the HDTV, best audio to the Onkyo. No muss, no fuss.

Clock Setting Procedure (digital clock page 242 of your owners manual)
1. Press and hold the time button until the hours blink.
2. Adjust the hours by turning the right side Tune/
Audio control.
3. After the hours are adjusted, press the right side
Tune/Audio control to set the minutes. The minutes will
begin to blink.
4. Adjust the minutes using the right side Tune/Audio
control.
5. To exit, press any button/knob or wait 5 seconds.

SETTING THE ANALOG CLOCK (page 238 of your owners manual)
To set the analog clock at the top center of the instrument
panel, press and hold the button until the setting is
correct. The clock will adjust slowly at first and then
quicker the longer the button is held.

If it is blinking it is in a 5 minute time delay.
It should settle to a steady snowflake after 5 minutes and come on normally.

5 blink indicates - AKB circuit (AKB), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. Also unit be in IK blanking, try turning up screen slightly.

Many of the later model Sony TV’s have a built in self-diagnosis function. If the timer/standby indicator is blinking, this could be an indication of a problem with the unit. The diagnostic blinking will occur automatically with no action required by you to engage it.
The timing of the blinking you see would be as follows: two to nine blinks, (depending on the fault), about a third of a second apart, then a pause for 3 seconds, then the two to nine blinks about a third of a second apart again.
Here is a list of the problems that might have occurred indicated by the number of blinks. The words in parentheses are those, which you will see for each of these faults on a diagnosis screen described later in this article.

• Unit is dead, No blinks - Problem in the standby power section. Might check fuse, R607, Q601, IC601, R612 and VDR601 (should show open).
  
• 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, check T603 and R672.
• Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505
  
• 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. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. 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. 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.
  

• Eight GA_googleFillSlot("TL-IMU-Article");blinks - Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code. Check IC406 audio amp, PS401, and 402. On some projection models of Sony TV sets, this code means that T8005 (flyback transformer), or the associative components in the high voltage circuits are defective on the D board.

• Nine blinks - Replace D 6116 and D 6301 on the "G" board, do not resolder as this will fix the problem temporary. Or Panel Module Error or Thermal Error. If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing, then change the switching regulator on the "G" board or check connections. 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.
  

press and hold the clk{clock] button for 3 sec while the time is displayed. the time indication will blink. rotate the mofe [audio control] knob to adjust the hours while the time while the time indication is blinking. when the hours has been adjusted, press the mode[ audio control] knob. rotate the mode [audio control] knob to adjust the minutes while thetime indicatiion is blinking. the time is automatically set 5 seconds after the minute adjustment. the time cam also be manually set by pressing the mode [audio control] knob
