It will be either BM board (Video Processor board) or Tcon Board (top side of panel). I have similar problem...my TV turns on, lamps turns on (you can see them from back side panel holes) but just a dark blue picture appears with no image (like picture when external input is selected without signal), no OSD appears....some times I can heard audio (using Antena).
I'm thinking getting the BM board.

sometimes defective capacitors are not noticeable visually unless we use an capacitance tester/instrument .better replace the capacitors at the secondary of the transformer and resolder the pc board .check also the connectors make sure that it fits the socket tight..good luck

let me hear if you have further question..

The fact that the screen illuminates properly and does not stay absolutely pitch black means that the backlights are working properly.

A faulty LCD Controller Board (or TCon board for short) could possibly cause the symptoms you describe. A replacement board can be purchased on Ebay for around $60 plus shipping. See the following link for one example:

However, if you are unable / unwilling to disassemble the unit and replace the component yourself, then you will seriously have to consider the cost benefit of risking more money trying to repair the unit. Sony products are generally pretty reliable and worth the effort of repairing, but a technician in the repair shop will probably charge you at least $100 just for the labour to replace the part, plus the cost of the part itself. I don't know how comfortable you are with repairing electronics since you said you had the power supply board replaced by someone else. You will have to weigh this cost against the price of a brand new TV which comes complete with a warranty.

Plasma and LCD TV sets are prone to having capacitors in the power supply section fail. This is the most likely cause for the probem you describe. When capacitors fail your will commonly see one or more of the following symptoms.

• No video, Power light is on or blinking.
• TV is making a clicking noise.
• TV takes a while to come on
• Screen is very dim or flickers.
