Screen will not light up.standby/timer light blinks continuosly

Faulty components from the secondary circuit section,, Try to check the Horizontal output transistor.

How many times do this standby light flashes at one time switch ON? Count it. These flashes are fault indications. From the number of flashes, you can get an idea about which section circuit inside it is faulty. After confirming it, If you wish to get more details of these blinking codes, check this link.

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.

check lamp first

This is a good indication that the picture tube is starting to fail. If you feel comfortable with the back cover off, try the following:

1) Remove the back cover (set the unit on the floor)
2) Locate the flyback transformer (part with large red wire coming out the top)
3) There will be one or two controls on it. One should be labeled screen and the other focus.
4) Turn the screen control slightly clockwise.

If the picture remains on, then the tube is starting to fail and the "fix" will buy you enough time to locate a replacement.

Update this with the results,

sounds like a power board problem

Blinking codes meaning:

• 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.

Good luck:

Dont forget to rate:

Ok. I think you'll need an IC or a PSU.

the blinking standby light should be a help. It should be blinking a repeating code. Can you post that here please?

Thanks,
Dan

I'm having the same problem. My stand-by light blinks 3 times though. The tv clicks as if it is going to turn on, but it never does. Is there a simple solution to this problem?
