Re: PS43D450A2WXXU picture quality problem

I am sticking with Vs=213 V and Vsc=-185 V. It is not fully gone but the area which has diffusion is only in the middle on the left side of the screen(before it was happening through the whole horizontal middle of the screen). And the diffusion is not as intense and frequent as it was before. It is only happening when the picture has big area of white or light blue on left side.
I have tried Vs=215 V but didn't see any difference. Also tried Vsc= -175 V but again no difference from -185V.
I have tired Vsc=-189 and felt it...

it measures -183 V, sticker says it should be -185. I am playing with this voltage now.

Re: PS43D450A2WXXU picture quality problem

Hi Tom,

I have tried to adjust the Vs and have to admit that the pink diffusion is now occurring less frequent and is less visible. I have gone to 213 V but was afraid to go further. Is there any safe upper limit of Vs to try?

Thanks.

Thanks again.

Hi Guys,

I recently repaired my PS43D450A2WXXU where I suspected that the Y-Main is faulty. Just to make sure I also ordered X-Main. After I replaced the Y-Main TV started to work however when I was watching the TV I have noticed this shivering redish/greenish maps showing up on the screen from time to time. It is especially noticable when the picture is purely white. As it is mainly happening on the side of the screen where there is X-Main I tried to replaced it as I had a spare part for it, but it didn't help. Any idea what can be wrong? Is it the display or do I need to replace...

Hi guys, I am DIY enthusiast. I am always disassembling any thing when it has signs of gone to a silicon heaven. Well just to find out how it works and potentially fix it. Electronics is my hobby when I have a time of course.
