    blinking 4 times in standby and won't turn on

  • themarkp Nov 26, 2008

    I have the same problem of being stuck in standby, but the blinking is a steady, constant on and off.  I tried the recommended unplug for 60 seconds and plugging into the outlet rather than a surge protector, but no luck.  Help!

    Does anyone have any idea what 6 blinks indicates mine is blinking 6 times after the power button is pushed..

    had a brown out... had the tv on a protector with a fuse.  It is blinking 4 times with a clicking sound as if it is trying to turn on but does not... then it clicks off.  My husband will attempt to fix this - we have been told it is either a fuse or a circuit.  Can we get schematics or can you tell us what to do?  KV32FS12 - Thanks, Chris

The 4 blinks indicate a vertical deflection problem. Either the connections on the legs of the vertical IC are bad or the IC is defective. If you can solder, you can fix this yourself. Let me know if you wish to attempt the repair and I'll provide more details and instructions.

This may be a vertical circuit problem. IC1509 is usually the vertical IC. If you can solder, I would first try an resolder the pins on this IC. If that fails to resolve it, replace the IC. This IC is a small flat IC attached to a heat sink with about 11 pins. It will be marked LA7837 or something similar. Feel free to post the marking and I'll confirm you have the correct IC.

Keep me posted.
