Samsung PCN5425R 54" Rear Projection Television - Answered Questions & Fixed issues

Useing remote by pressing (info-menu-mute-power) turn off tv and press this bottons.you will get reset option on screen Thank you

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.

Yes,this is 100% convergence problems,it dead.The tv colors lines R,G,B mis alignments any parts of the screen,have colors shadows pictures or 3D pictures look alike?The tv convergence board have dead 2 STK convergence ICS and some or all of it resistors too.The tv convergence board,must have these parts to be replaced on it to solved the tv picture convergence problems.Try website like Tvrepairworld.com,might can still buy a whole refurbish convergence board to do the replacement.The Samsung/Akai DLP Tvs used the same convergence board.Or the shop,will cost u like $300-350 for parts and labors.

Lamp is nearing end of life and needs replacing.

I hope due to dusty inside your TV at switch panel its may happens like this or the rubber pad inside at switch part my collapse...... which results high volume suddely

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

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.

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.

You probably also have a bad digital convergence box. I have a tip at http://www.fixya.com/support/r4273935-replace_digital_convergence_box which explains how to fix the problem and where to get the parts. Let me know if you need more help. Thanks for using FixYa and for the generous rating.

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

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.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms

• Screen Looks 3-D
• Colors wont align
• Screen may look distorted or warped
• No Audio/Video - makes a chirping sound.

Problem #2

Another common problem is dull or washed out video.
Your TV may have one or more of the following symptoms....

• Dull looking picture
• White looking picture
• Halos around objects
• Red/Orange looking picture

Hi


Thanks for using FixYa. From what you have described it seems that you have to replace the convergence IC and check power resistor for leakage, if values are not exact you have to replace them. The typical cost to get this fixed by a pro is about $300 - and it doesn't mean that he/they will do a job better than you do. The parts are less than $100 (about $20-$30 for the IC's) if you want to do it yourself. Replacing only the IC's MAY solve the problem; however, many people have also had blown resistors requiring replacement. Why would you ask should you replace both of the IC's if only one is shot?! If one is shot the other one is not far away and for that little price of the chips it worth changing them both at the same time. Also the convergence board should be checked for cracked solder. If you replace the ICs and the resistors are shot, the ICs may blow again almost immediately, meaning you may have to do the repair twice. Please do rate the solution if the issue is resolved or else revert for further assistance.

COULD BE A DIRTY CABLE CONNECTION TO THE Y-BUFFER BOARD, OTHER WISE YOU WILL NEED TO REPLACE THE ENTIRE SCREEN, VERY EXPENSIVE REPAIR

MY SAMSUNG TV MODEL NUMBER LE32R87BD IS DISPLAYING A RED FLASHING LIGHT ON THE POWER BUTTON AT THE FRONT OF THE TV THERE IS NO PICTURE PLUS IT WONT TURN ON CAN ANYONE ASSIST ME WITH THIS PROBLEM
