Sounds like the vertical output is causing the CRTs to shutdown for protection. Try resoldering the vertical output IC that will often correct the problem. If not the vertical output IC may be defective.

Distorted picture


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. To get fixed either call in a local TV repair company or goto sites such as Tv Repair Kits to get a repair kit with instructions. Here is there link.

Coloring is off and there is a ghosting effect


Hello,

Part # BP95-00142E is the correct convergence amp board for a model # HCN4226W. Part # BP94-00155A is listed as a "CG Amp assembly board" also, but is not correct for a model # HCN4226W. They are both basically convergence amp boards. Here's a link to order the original Samsung covergence amp board for this model (HCN4226W) from a major parts distributor:

Picture from 60" to 19" then gone.


The fluid is a fairly easy replacement. They just need to remove the CRT with the bad fluid and drain the old fluid and clean the CRT and then replace the fluid. The Shrinking is just a Vertical Deflection problem which is also an easy repair. A new Vertical IC and a couple Capacitors. In my shop it would run @ $200.00 to fix both.

Red color lamp going in and out, how much if replaced


A shop would charge about 350 to 400 for the CRT and at least 150 to install it.Its an expensive repair as the crt is pricey. Have you tried to trouble shoot the red drive circuit as it may be something simple such as an output transistor being faulty, or a solder connection on the CRT socket itself.

Bad picture


You have a bad picture tube or a bad driver signal that drives the CRT. Could be a bad capacitor in the boost voltage circuit also. if you have no TV repair experience, contact an Authorized Sony repair center to have a look and assist you in the repair of this TV set. Good Luck

Samsung Convergence Problem


It requires some pretty good solder skills and there may be a couple of resistors that need to go also. Take that CG board out it probably doesn't need it and you will likely have to completly re-align the set after repairing it with the new CG in there, just the IC's and resistors usually require minimal alinment
