Question about Samsung HCM5525W 55" Rear Projection Television

1 Answer

XBOX 360 to Samsung HCM5525W high def convergence issue.

Answer me this. I recently replaced the STK convergence IC's to get the convergence back. The screen looks great now after doing a Point to Point convergence setting. Now the problem. When I set my xbox 360 to 1080i or 720 the convergence on the desktop of the xbox goes crazy. It looks like it did before replacing the IC's. Does anyone think the high def in the tv could be at fault or could it be the xbox? Side note: I just got the xbox back from being repaired by microsoft.

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.

They have put together complete kits for most models that include the parts, step by step photo instructions, repair assistance, etc.

My samsung rear projection tv has a problem with its convergence ic. i think theres two ics , but how do i tell which ic need replacing??


Always replace both once your going to the trouble each IC is usually less than $30.
This link will help show you what's involved.
convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually $200-$400 Be sure to vote/rate me if this helped Thanks!

Probable bad convergence IC's---STK units on large heat sink.

Also,possible blown fuse (soldered-in) hidden under heat sink.

Samsung is known for making the fuse devices hard to find.

Let me know if you need more help....T.

The Samsung has bad convergence IC's most likly. This should be repair ONLY by a trained technician as a TV set is not a place to experiment or tinker with because of the extremly high voltage inside. This repair should cost you in the range of 250 to 400 bucks . Good Luck
