Cant align convergance

Posted on Oct 23, 2008


It probably is see if you can align the convergence manually or auto if available, you can order just the convergence ic's or the convergence amp board, whichever you prefer. check pricing and availability. also check Blue crt for faded picture, usually dirty crt fluid, makes picture dark and discoloured. If it is you may need to replace the blue crt also. this gets a little expensive, again check pricing hope this gets you started RFT

When switched on colours fine after short period colours seperate causing a 3d type effect

Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs.

My tv has lost its colour, and its green or yellow sometimes.

Okay that means the other GUNS went out when i refer to guns I mean the other blue and red, they need to be replaced pretty costly but if you value that TV I'd do it.

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.
