Horizontal lines can be cause by many things. One of which is the convergence module. $130.00 is a little high for something that can be caused by other things as well.

Very easy repair....Just replace the convergence amp board part# BP95-00142E (about $80) It includes both convergence IC's and associated components (Five connectors,one screw,easy access)no soldering...

You don't have a color wheel in this model. There is probably a fuse blown that you missed or a resistor in the circuit outside the convergence IC's (STK 392-040). Did you press the perfect focus in the convergence part of the menu?

If it is rear projection set it uses either two of the STK-392-020 OR STK-392-040 CHIPS FOR CONVERGENCE OUTPUT.

BOTH WILL HAVE TO BE REPLACED; NOTE THAT THESE SETS ALSO HAVE "PICO" FUSES ON THE BOARD FOR EACH CHIP--no movement means one of the fuses is blown because the chip shorted.

This can be a do it yourself repair if you are handy; total parts cost if the parts purchased on Ebay is under 30 dollars.

Let me know if I can assist you and if you have any questions reply to the posting here.

This unit does not have a lamp inside. It is a CRT Projection unit. What is the symptom of your problem?

Samsung PCN5425R... | Answered on Aug 31, 2010


iF It only does it from the box either the cables are bad (unlikely) or problem is coming from box.

Two things to do: unplug box and let it reboot.


Have provider bring a new box to correct problem; component is Red, Green, Blue video with info---one messed up and bingo.

If not on regular cable the set does not know what is hooked up to it.

Get another box and get back on line.

3 blinks means that the pwer source is in protected mode becuase the high tension output is shorted - most likely the horizontal main deflection transistor has failed. Since usually this failure also damages all the connected components you should replace the entire board. Here it is

If one of the 3 bulbs goes out you will have color distortion. I have also seen in some older Sony rear projections heavy loss of focus can be the result of a dead bulb.

Without any power going to the TV, it's likely that the power supply has been fried. If you feel comfortable opening the set, you should check where the power plug goes into the power supply and locate the fuse. The fuse is a small glass tube with metal rings at either end. If you take the fuse out of the holder and hold it up to a light, you can see whether or not the filament (the little wire) is still connected. If it isn't, and if the area's black or brown, then the fuse is blown and needs to be replaced.

What ur "PROBLEMS" discirbe that first.Than i can help u determine which the boards $75 or $26 that will work for U.

Samsung PCN5425R... | Answered on Apr 22, 2010


well, at this time using the remote to adjust is not doing any good anymore. should replace the IC and it's not that expensive. go to Partstore.com and they should have a convergence board for about $76 or you could buy the parts and put it together by soldering.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.
