  • Inspect all electrolytic capacitors on the power supply board and replace any that are bulging or leaking.

  • On my board there were 2ea 2200uf capacitors that were bulging.

  • Remove the old capacitors ensuring you don't overheat or damage the copper pads/tracks on the circuit board

  • Take care to ensure you install the new capacitors correctly. They are polarity sensitive and the board and capacitors will be clearly marked which way they should be inserted.

  • You may want to check and replace any adjacent capacitors that are rated 10V as these seem to be the ones likely to fail.

  • In my case I also replaced the 1000uF capacitor

  • If you have a different model TV the layout of the power supply board may be different however the faulty capacitors should be easily identifiable.

  • If replacing the capacitors does not resolve your symptoms you may need to replace the eprom on the main board as it can be corrupted or damaged by the power cycling
