Re: samsung ps42q96hd

hi tom , does the tv need to be on ,, and what do i set the multimeter at

[tom66]

Re: samsung ps42q96hd

Yes, TV should be on, use the same multimeter settings as before to test Va.

Re: samsung ps42q96hd

it reads 637

[tom66]

Re: samsung ps42q96hd

63.7V, both sides of fuse, red on each end, black on ground/chassis of TV?
Assuming you did the control board jumper correctly, the fault must therefore be on the control board.
Please show me how you set up the jumper & LVDS unplugged so I can confirm.

Re: samsung ps42q96hd

yes it was 63.7v eash side ,i use a clip off the end of wire to attach to a speaker and placed it on the top 2 prongs,unpluged the cable that goes to the av board , then plugged the tv in ,then switched it on , came on with nothing on the screen ,,

Re: samsung ps42q96hd

Was the screen still glowing slightly after you did this?

If so, the control board is most likely the fault.

Re: samsung ps42q96hd

yes screen was still glowing ,, does that mean a new control board?

Re: samsung ps42q96hd

Hey guys I have exactly the same TV however the fault with mine is I have no VS voltage present which should be 205 VDC, I'm lost as to whether its a power supply fault or AV board fault

Is there a test I can do to narrow down the fault

any advice or help much appreciated

Need to start a New Thread--This is a different set with a different fault from the O/P.

BTW--Unplug the PSU to Y-Main thick cables and re-check Vs and Va at the PSU.
--These absent--prob duff PSU

IF they come up within a couple of seconds of switch-on then decay, could be something else causing a protection shut-down.
