Recently had my TV diagnosed by an authorized Sony repair shop for the 10 blinks problem. They said I need a new D Board and they want $900 to fix. That's almost as much as I paid for the TV and I could easily buy a new 46 inch for that much.
Anyway, I figure I'd try to repair the D Board myself, and I am a Electronics Repair Tech and have experience soldering. I have a repair manual, and for HV Protection problem it says check q8014,q8013 & r8051 on d board, does anyone have the part numbers for these? That way I can just replace them all, obviously if the IC is bad, I'll have to replace the board. I figure I can replace these parts before I spend $350 on a new D Board, IF I can still find one.
Thanks in advance for any help.

I did locate the part numbers you are looking for the IC 8005 part# TL1431CZ-AP the Q8013 and Q8014 part# 2SK3568, the R8051 is a 0.1 1/2 W :RF. I located the parts at WWW.PARTSTORE.COM

3-1. HV REGULATION CIRCUIT CHECK AND
ADJUSTMENT
When replacing the following components IC8005 always check the HV regulation, and if necessary
re-adjust.
HV REGULATION ADJUSTMENT
1. Receive the all white signal.
2. Set PIC MAX/BRT CENT.
3. Connect a HV static voltmeter to the unconnected plug of the
high-voltage block.
4. Power on the set.
5. Receive the all white signal.
6. Set PIC MAX/BRT CENT.
7. Confi rm that the static voltmeter reading is 31.0 ± 0.3kV.
8. If not, adjust with RV8002 to the specifi ed value.
9. After adjustment, put the VR cover on RV8002 (as shown below) and
apply suffi cient amount of epoxy resin around RV8002 .
Remove the cap from
the unused terminal and
connect a static voltmeter
there.
