Question about Televison & Video

1 Answer

I have at 42in Plasma Samsung HPS4253. One day randomly my TV had red pixels all over the place. Anytime the screen goes ''black'' it is now red. When watching TV or movies any shadows or black sections on the screen are now red pixels. I have changed all my inputs to the TV and nothing changes. Is there something I can adjust at home to fix this. If not how much will it cost to fix this?

If the picture has red 'staining' all over the picture which is static then the fault is the Xsus pcb. If the picture has random 'sparklies' that change then it may be a case that either the ppower supply Vs voltage has deviated from its set voltage which can be adjusted by a potenitometer on the psu pcb...or if the psu voltages are correct (when compared to the screen label factory voltages) then by tweaking the Ysus trimmers, The fault could be a deviated tolerance on the Ysus.

It depends on the size,location and how many dead pixels. If remember less that 5 they won't do nothing about them. Call the warranty people and find out. they will for the location, size of pixel and quantities. Good luck to you.

I have posted this in other areas and it appears to be a diffusion problem meaning the panel needs an electrical adjustment and can be done by a technician or you if you dare. Depends on how handy with electronics you are. But there are some adjustments you can do to minimize or remove these red or blue pixels firing randomly. Try adjusting V-SUS, V-SET, and check all other ones. VE, VS, VA, and see what happens. Write all voltages down first then go tweeking. I do have a bulletin here that states exactly what to do, I just have to find it. Let me know if you have any luck with this procedure first. Oh Yea, make sure you use the internal generator, the wipe screen from black to white so as to see both at the same time while adjusting the picture. It helps to have it on the stand when doing this procedure. Let me know if i can be of anymore assistance. Cheers. Jay

There is some voltages that need adjusted in your tv and possibly the z sustain board needs replaced if the voltage adjustment doesn't fix it.

42in Samsung with horizontal lines/static


1st thing to do is to check its parts if it has a losen leg,then you have to check the horizontal out(H-Out) it is one of the larger transistor and it commonly place beside the Fly back X former ,the best material to used is multitester, and if it didnt work try to check the filter capacitor( it is the largest capacitor) And also check other capacitor, tnx hope it will helped you!
