Question about Samsung HP-R4272 42 in. Plasma HDTV
Thanks for using FixYa. You’ll need to check the X and Y sustain buffer boards. When either of these boards goes bad common problems include negative image, no image, vertical or horizontal stripes on picture, turns on and than turns off, and many more. You’ll need to open the back off the TV and check for any swollen/bulged capacitors on these boards and replace whichever has gone bad. If still the issue is not resolved, then please check the power supply board. All this is only recommended if you have electrical expertise & know how to solder/re-solder components as these units contain high voltages even when switched off. Please do accept the solution if the issue is resolved or post a comment further assistance.
