Question about Samsung HP-R4252 42 in. Plasma HDTV

2 Answers

I have a Samsung HP-S4253X/XAA Plasma with coloration problems

My TV is about 15 months old and is now starting to show a bright purplish tint to high contrast images, i.e. faces, whites etc. Usually not all over the screen but only when in high contrast Blacks in background. Does anyone have any idea what might be causing this???? It seems to only do this when it has been on for an hour or so and the input source does not matter. Antenna, HDMI, or Component. Thanks,

The problem is normally called "Diffusion". It's the most common problem I come across on Plasma televisions. If this is your problem, then, the VSCAN and/or the VS must be adjusted (usually counter clockwise about 10 volts). The VSCAN is adjusted first and will remove most, if not all the diffusion. If you need a technician in your area, contact Samsung at: 1-800-samsung. If you like, respond to this post with a picture and we can analyze it further.

Vertical Line started on left side of HDTV, and now


This problem is down to the actual LCD or plasma screen, if this shows as the screen warms up and stays on then the screen will need to be replaced, you should go back to your retailer (not manufacturer) and report this problem, depending on the store and how long you have had the tv, the tv can be replaced for a like for like tv at store as this is not a cheap standard repair.

it depends on what your using it for, adjust colour tones to what you think looks natural, contrast between 80-90, keep sharpness below 30. just have a play around till you find what best suits the source material.

Color bleed thru problems


this set only has a 12 month parts and labor warranty so you need to call 1 800 samsung or the dealer you bought it from..the problem with adjusting the v_set and v_scan voltages is it may last for 6 months and then you would still need a new plasma panel..better to have a samsung authorized tech check it

Blue snowy pixel areas on my plasma


some of these panels were mis-calibrated from the factory after not aging long enough. Let the TV run for atleast 2 hours and adjust the Vs and Vscan voltages. When it is blue in the left I have found generally the Vs is about 10 volts too high.

Blue tint


This is usually caused by an over voltage on one of the panel voltages, if you open up the set and look at the panel you will find a sticker with the panel voltages on it, if you adjust the VS voltage down about 10 volts it will go away, if it doesn't the adjust the Vscan voltage down about 5-10 volt
