Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Problem with ballast, or power supply, supplying voltage to the ballast.

I had the same problem with the exact same TV. I took it to a local TV shop. My problem was fixed by replacing the T-Con controller board. The cost of the part was about $85 and labor $125. There are no "new" parts out there for Olevias because the company is out of business but I did find a part pulled from a "damaged in transit" TV. It's a personal decision (assuming the parts can be found) as to if its cost effective to repair the TV.

I think a new lamp will solve the problem. It may need a claeaning. This TV is known for optical block failures soon after a lamp replacement. Call Sony for details

id take it and have it repaired. people on here can tell you what they think it is but no one knows for sure what is causing the problem. a repair shop can guarantee the repair.

sounds like a solder issue. try resoldering the Ics that are attached to heat sinks on the Board that has the flyback also resolder the flyback pin connections

This is very common in Samsung DLPs. The DMD board is going bad. You will need to replace it.

Lamp life is only a few thousand hours. Hopefully its only the lamp that made to noise. Don't turn on again until lamp is replaced.
