It sounds as you desribe, the vertical output IC and or the b+ feed capacitor off the Hi voltage transformer feeding the vert. IC its required voltage. Not a really hard job to replace, but not for a handi person to do. This should be left to the professional, as there are no user serviceable parts inside this set and with the HI voltage and the safety issues its best to call somesone to assist you with this repair. Good Luck

iv'e run into this before, you have closed caption text 1,2,3 or 4 on. this is different than the normal "cc" cation. just go into your menu & turn off closed caption.

On the reomte control (bottom) left of the sleep button is a cc button, push that until "OFF" appears on the screen. The close caption box should disappear. It worked for me, finally.

It is a hardware problem. you can repaired it from service center.

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. The Tcon board is usually located under its own RF shield and will have a large braided steel multiwire cable coming into the bottom of the board and several flat ribbon cables connected to the top by little plastic flip up connectors. A replacement board can be purchased on Ebay for around $70 plus shipping. See the following link for one example:

Just use your mouse to click on the link, which is the underlined and highlighted text just above. This will open a new web browser page automatically for you and allow you to view the item information at the website indicated.

Just don't buy any that say AS IS for their description of condition. That is EBay speak for broken.
Make sure they say TESTED FULLY WORKING in the item description.

The best way to be sure you are getting the right part is to open up your set and check the part number that is printed directly on the circuit board itself. Then look that part number up on the internet or type that number into the EBay search box.

Just typing in the model number of your TV will sometimes give you a few different part numbers so you have to confirm which part is in your particular set.

Make sure any part that you order online has exactly the same part number as the one you are replacing. Sometimes it it just the last few digits that are different and it can make a difference.
