    Thanks for the heads up regarding the fuses and the resistors.I don't have a schematic ,can you tell me what the fuse numbers/ resistors are that need to be checked. I did a visual check around the chip but its not that easy to check the inputs and outputs of the chip without a designated #.

    Thanks for help

Hi, Yes! the convergance board can stop the unit from coming On. No need to change the board, just change the ICs. This is what it looks like,you will have to remove the board from the unit take note of the wires before removing them, -Tv  is dead - 794a500.jpg

    Thank you; one more thing, you will need to use a tester , to check some very small fuses and low value resisters. On the same can do it.

    Hello missileman,

    Okay the fuses are what we call micro fuses, you will see some on the main board.....they maybe colored yellow or green, people takes them for resistors, next to it you will see F801 and so on . The resistors are standing up on the board with the STKs, and they are going to the IC pins, check all of them....the first thing , is to put in the ICs, maybe that's all you.

2003 Samsung HDTV 1080i 42" wide screen has just developed picture problems distorted and red. Almost looks 3D. MODEL NO.:HCN4226WX/XAC SERIAL NO.: 37083CEX400297E

This is a convergence problem and can easily be fixed either by resoldering the pins on the convergence ICs or by replaceing them if they prove to be defective. Can you solder? Do you feel confident in replacing these parts?
Keep us posted.

2006 42'' Samsung rear projection, Balist????

A Ballast is a circuit that provides voltage to Lamp. Ballasts are only used with TV's with a Lamp. According to your model number this unit does not use a lamp. That model number uses 3 rear-projected CRTs. The most common units with a ballast would be a DLP HDTV.

The Model number you specified HCN4226W is a unit made in 2003. However you stated in your subject line that this was a Samsung unit from 2006. Please verify your model number.
