Sorry this is late, but for anyone else who needs this info - here it is.
If your 170v is loading down when the tv is turned on, it is one or more of the current sense resistors making a poor contact.
They are .47ohm surface mount resistors. There are three of them located right by q14 & q15, near the largest capacitor on the board. Resolder them (both ends of all three of them), or replace them with a .15 ohm resistor.
Hope this helps.
You information is certainly not too late...............
Having put the screen away until I had more time, I finally dug it out again today. I re-ran the test and then re-soldered the three resistors you identified.
What can I say except:
Many thanks, grazie mille, tusen tack, muchas gracias, merci beacoup, danke schön, dank je wel , ta very much! (that's about the limit of my language abilities)
I have now repaired both my screens, and identified that the resistors are the problem on a third power supply I have. Wooo Hoo !
All the very best, you are a star
