My Sony KP51WS520 had the 10 blinks and I change the D board. Unfortunately, D board are not available anymore, except thru exchange at Valley Service in 2810 West Valley Blvd., Alhambra, California; They repaired the D Board for me when I brought it in the morning and I pick it up in the afternoon. After putting the D board back on my TV it worked perfectly. Thakn you for your help and saved my hundreds of $$$$ in repair.

I can post the picture of the D Board for others to see  but don't know how. Can you help  me post the picture.

Thank you. 07.16.13

Ok, I've searched and found this thread which explains my issue but I have another problem with my KP-51WS520 . When taking out the G board I had trouble pulling the ANT GRD cable and pulled the male end right off the board with it. My questions are is this connection necessary and what does it do? What do I call the piece I pulled out from the board and can a new one be purchased? Also, does it have to be put in any particular way pos/neg? Thanks for any help you can provide. This forum has been very helpful so far and I can only hope someone can help with this.

Yes, the ANT GND connection is required as it is the ground for the G board.

Thanks, can you tell me what the part is called and if it is directional positive/negative? Also where can I get the part?

Unfortunately, I am not at home now and do not have access to my collection of service manuals. I will check when I am home.

The part number information for the ANT GND 3 connector is as follows:

Component Part No. Description
CN6004 1-695-915-11 TAB (CONTACT)

Unfortunately, the part is not in stock. Go to https://servicesales.sel.sony.com/ecom/ ... /index.jsp. Use the Part Number search to locate the part. To access the Part Number search, click any accessory category and wait for the next page to appear. A new search option will appear at the top right. Click the down arrow to select the Part Number search.
