Question about Samsung 50 in. Plasma TV

5 Answers

I have a Samsung 50" Plasma TV (PS50C96HDX/XEU). The problem with it is that: 1) It can only be switched on via the On/Off button in front ot the TV 2) It does not respond to the remote control 3) It only responds to one or two buttons on the side of the TV 4) It changes source from TV to AV to DVD all by itself.

    I have bought and tried a new PCB Main Board with no success.



    Please what is the IR board?

  • rol2y Feb 03, 2009

    Is the IR board same as the PCB Logic Board?

  • rol2y Feb 03, 2009

    I need to know what parts I need to change or action I need to take to solve the problem then I will accept.

  • rol2y Feb 03, 2009

    I already tried all the minor troubleshooting like changing batteries.



    It also does not respond to the batteries on the side of the TV itself. And on its own, it changes channels and source of input.

    The remote control is not the problem. The remote control works perfectly with my Sony VCR.

    The TV ALSOM DOES NOT RESPOND TO THE SIDE BUTTONS ON THE TV.

    The remote control is not the problem. The remote control works perfectly with my Sony VCR.

    The TV ALSO DOES NOT RESPOND TO THE SIDE BUTTONS ON THE TV.

  • rol2y Feb 03, 2009

    I HAVE BOUGHT A BRAND NEW PCB. IT DID NOT SOLVE THE PROBLEM. I STILL HAVE IT WITH ME.

    PICTURE QUALITY IS OKAY BUT THE TV CONTINUES TO CHANGE CHANNELS ON ITS OWN. NO RESPONSE TO BUTTONS ON TV OR REMOTE CONTROL.

  • rol2y Feb 03, 2009

    SINCE PICTURE QUALITY IS GOOD, AND I HAVE ELIMINATED THE PCB MAIN, WOULD YOU ADVICE I CHANGE THE PCB LOGIC MAIN AND THE PCB POWER SUPPLY BOARD?

    Ronnieh49,
    When you say change both boards, do you mean I should change the PCB Logic Main and the PCB Power Supply boards?

    Is this same as complete rebuild? Because since the picture and colour is okay that should mean the PCB Y boards are okay?

    I am ready to accept once I get confirmation.

  • rol2y Feb 03, 2009

    I am going to carry out the recommendation of Ronnieh49 that I should change both boards. I pray it does work. I will come back to rate this after I have tried the solution.

  • rol2y Feb 24, 2009

    Problem finally solved. Not the PCB Mian Board, Logic Board or Power board. The problem, the Powerbutton/IR sensor board.



    I disconnected the Powerbutton/IR sensor board et voila!! the dise control buttons all working perfectly now. All I need do now is change the IR sensor board. Itsy bitsy thing to cause all these problems n'est pas?

Unfortunately you have major board issues and possibly many solder break points.i recommend a total rebuild. if you have a warranty, i would defiantly use it immediately.

Hi

Change the batterys in your remote controller, check for stuck buttons, check the battery contacts and that they are the right way in there. sometimes the batterys might not touch the contacts properly and the remote wouldn't get power.

How old is it? got warranty on it?

    This is the PCB,The IR is located on this board and could be a loose soldier joint or a bad component

    You should also check the control board that the ir sensor and buttons are connected to.

Hi my samsung plasma ps50c96hdx/xeu powering down, pressing power button has no effect to turn on again.Powers up by unplugging 5min then starts working. now powering down more frequently. Please help


Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time; especially to Plasma displays. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Our Samsung HPN5039x Plasma TV isn't turning on: when we press the power button, the red power light flashes then turns off. What do we do?


Hello, It sounds like you have a defective power supply. Typically, +5 volt stby is present if the TV switches on with front indicator light. On the power supply, connector 802 pin 4 is the on command from the pcb main to switch the p.supply on. If this signal is present but still no VS,VA,VE panel voltages are missing, the p. supply is bad. Good luck!

No picture, just sound on my 50 inch plasma tv


Does it show a Menu at least? If it does then just switch through the INPUT until you see a picture. Cables most likely to be Video 1, 2 or 3. Video games "LINE", or HDMI..of course "HDMI".

Your remote should have an "INPUT" button.

Short circuit on the "Y" sustain board


The problem is heat!!! If the tv has fans they should be checked for normal operation,although on the early samsung models there were none, and the problem is that the panel drive buffers are getting to hot due to inadequate cooling. This is most apperent when tv is mounted to close to the wall, also external fan blowing on the rear left side will dissapate the heat. It is a problem on early Samsung and Electrograph 42 " plasma models. Hope this helps.
