Question about Samsung HCN4226W 42" Rear Projection HDTV-Ready Television

1 Answer

My samsung hcn4226wx rear projection tv

I have two major problems with the picture quality. There are tiny purple and red zig zag lines on the screen which appeared first for a while followed by horizontal lines or shadows that seem to be created from text or lines from various graphics within programs and alter position when the screen changes. Would replacing the main board solve these problems?

We had a power outage and since my tv does nothing, a tiny red light says standby but nothing changes.


Sounds like The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electro-medical.blogspot.com/
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Samsung TV Displaying Dual Images. It appears as 2 of the same images offset from each other. There are also some lines in the images. Talked to samsung and they wanted to send a tech but I simply can't...


Overlapping video signals are generally adjustments made when turning various pots on the rear circuit board. You may need the service manual to follow the directions on how to reset and stabilize the picture. If you cannot be your own technician; you have no choice or other options.
