Re: samsung ps43d450
I'd check Vs & Va on power board are matching the panel sticker.
Then Vscan & Ve on Y-main & X-main respectively.
(Ve not marked but in the range of 90~110V)
For reference:
- pic 1 is X-main
- pic 5 is Y-main with Y-buffer (green)
- pic 7 is power boardLast edited by tom66; 11-16-2014, 04:38 PM.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: samsung ps43d450
Ok, try set Vs to 215V and Vscan to -200V. Use adjustments on power board and Y-main to do this.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: samsung ps43d450
Cool, now go to the SAMSUNG website and download the latest firmware for this set, put it on a USB stick and install it on the TV. This will prevent the issue getting worse.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: samsung ps43d450
hi, googled for symptoms, and it brought me here.
at first there was no picture after approx. 1-2 minutes after power on, but sound was on
now it has picture, but it is gone yellow, and red pixels appear at larger parts of screen
same model, except on the sticker values are as follows:
Va 58
Vsc -180
Vs 207
Ve 0
Measured values are:
Va 81
Vs 320
Vsc -260
any help would be welcomed

Re: samsung ps43d450
I am no expert but I think as panel ages voltages need to be adjusted to compensate. Correct voltages on plasmas are critical. That is why there is a sticker on each panel. When voltage adjustments don't correct problem anymore I think panel has reached end of life.I assume no responsibility for any stupid suggestions I might post.
