If this is an HCN4226 open the back and locate the convergence board - it's up and to the left mounted on the frame rail. Unplug the power to it, the board is marked with a +/-20v symbol. Now plug the unit back in and try to power it up. If it comes up and has good sound that convergence board board needs to be repaired. The amps on it need to be replaced and both the return and line resistors have to be tested and replaced as needed. Some shops, ours included, have started offering cooling packages to help prevent this circuit from overheating by mounting a cooling fan directly in front of the amp board. It's an inexpensive measure to help cool that circuit.

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.
