The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Hello... I would start by getting the correct lamp for the TV, and I would advise getting an original equipment lamp. The lamps and ballasts are matched by wattage and operating voltage, and a mis-match will at best cause early lamp failure. The sound you are hearing could be the ballast trying to ignite a bad lamp caused by a mis-match. I hope this helps!

You have a bad audio output IC in the main board, you have a couple options as long as you don't use the sound from the is order a new main but if it was me I would take the back off and follow the wires that go to the speakers and unhook that plug.

You might want to try blowing it out with air, I have a toshiba that has had a similar problem and that always fixes it for a year or so. The problem is caused by the small cooling fans on the circuit boards, they get clogged and don't cool the board properly. The startup problem is also linked to the fans, they must run at speed or the board shuts down. I used an air compressor and took the tv to the garage to blow it out, you will need to take the back off and blow it our really good, and make sure to get ALL the small and large fans really clean, mine has four fans. Hope this helps....GOD BLESS...Randy

first try re-seating the lamp by pulling it out and sliding it back in. You would need to take off right side back cover. Sometimes this can clear the error and may fix the problem altogether. If no, try clean All the fans inside the Television to preserve the life of the lamp.

The main board is more than likely the cause of the trouble. Time for a new TV.
