How to find D6116 & D6301

Looking to find part D6116 and D6301 on the G board. What Iam seeing is a D with a mark through the middle of it or its a B. Would be a little black square on top of the solder and D6301 looks like a diode with two legs going through the board.

Red lite blinks tv will not power up. Sony kdp-51ws655

You need to count the number of blinks between the pause. Most common is 9 blinks. Also- after you press POWER, do you hear a "click" or not? If no click and 9 blinks, you probably have a "zero detect circuit failure" and have two options:
.
(1) Replace the "G" board (part # A1054157A) or have it repaired (they repair it on eBay for about $40. You ship them the bad board and they repair it and return it). A new board costs about $80 on eBay without having to send them your (core) bad board. Sometimes they are not available and you must send your board in for repair. this is MUCH less expensive than SEARS, which charges several hundred dollars.
.
(2) Repair the board yourself- by replacing the two diodes on the "G" Board - (D6301 which is on top- by the small transformer) and (D6116 which is an SMT component on the bottom of the board- it takes VERY steady hands and a good solder iron). The parts should cost less than $25 and are available on eBay by searching for "sony a1054157a".
.

Location of the "G" board. Unplug the TV set, leave it for 10 hours (to discharge the capacitors). Remove the brown back, carefully unplug the cables, unscrew the two mount screws, and unclip the front retaining tab.

This is the MOST LIKELY failed component, D6301. It is a diode and MUST be unsoldered and replaced. Make sure you know that diodes have a SPECIFIC way they must be installed. Note where the stripe is on the component. You can locate a "good" diode by searching on eBay for "sony a1054157a". You should see a parts kit for about $25, give or take.

One other possible culprit is the D6116 diode. This is a surface mounted component (SMT) and will require a steady hand and a very fine-tipped solder iron. I would replace the D6301 FIRST and re-connect the "G" Board to see if that is the ONLY culprit. If you STILL have the same problem, then replace D6116.

No picture or sounds red light blinks 10 times

The parts you need are two diodes, D6301, D6309, and D6116, Sony part numbers 6-500-567-21 (D6301 and 09) and 8-719-081-97 (D6116), they are located on the G board, and that's located on the left side of the set, as seen from the back.

D6116 is connected to pin 9 of transformer T6101, and D6301 and 09 are in series off of pin 7 of that transformer.

I would suggest not to desolder that transformer until you are certain that is defective.
Try to change D6116 and D6301 first.
You can try Radio Shack or check this site.
