    DO YOU HAPPEN TO KNOW THE NUMBER? I'LL TRY TO FIND IT ELSEWHERE

  • dondjohnson Jul 24, 2009

    IF IT'S THE SAME BOARD AS THE POWER SUPPLY BOARD I BOUGHT THE SECOND UNIT FROM SHOP JIMMY. IT DOES THE SAM THING. NEED MORE HELP. WHAT'S THE PART NUMBER SO I CAN SHOP FOR IT.
    THANKS

  • dondjohnson Jul 24, 2009

    SORRY ABOUT THAT. I'M TRYING HOW TO FIGURE OUT HOW TO USE THIS FORUM.
    THE TV ONLY HAS 2 BOARDS. ONE LOOKS TO BE THE MAIN BOARD FOR THE TUNER ETC. THE SECOND A POWER SUPPLY BOARD THAT I REPLACED WITH ONE FORM SHOP JIMMY HAS 2 CONNECTORS WITH 2 WIRES EACH THAT LOOK TO GO TO THE DISPLAY. IS THERE ANY I CAN CHECK FOR VOLTAGES TO DETERMINE IF THE OUTPUT FROM THE BOARD IS GOOD? I WOULDN'T THINK THE NEW BOARD WOULD BE BAD AS WELL AS IT DOES THE SAME AS THE ORIGONAL ONE.


  • dondjohnson Jul 24, 2009

    I DON'T KNOW WHAT TO CHECK OR WHAT I'M LOOKING FOR.
    CAN YOU HELP ME WITH THAT?


  • dondjohnson Jul 25, 2009

    CAN YOU OR ANYONE GUIDE ME WHERE I CAN GET A MANUAL? THAT MIGHT HELP FIND THE INVERTER.

  • dondjohnson Jul 25, 2009

    SORRY, THERE ARE 2 CONNECTORS WITH 2 WIRES EACH COMMING OUT OF THE MAIN BOX THAT GOES TO THE AREA YOU DESCRIBE. INSIDE THEY CONNECT TO THE POWER SUPPLY BOARD. THERE IS NOTHING IN BETWEEN. SURE WISH I COULD FIND A REPAIR MANUAL, EVERYTHING WORKS EXCEPT THE BACKLIGHT WON'T STAY ON. IT POWERS ON AND ALL IS OK FOR ABOUT 30 SEC. THEN I HEAR A FAINT CLICK AND IT GOES BLACK. THE SOUND CONTINUES, THE SCREEN IS STILL DISPLAYING THE VIDEO CAUSE I CAN SEE IT WITH THE FLASHLIGHT TRICK. IT SEEMS I'M SO CLOSE, BUT SO FAR.

  • dondjohnson Jul 25, 2009

    THANK YOU MUCH. I HAVE NOTHING THAT LOOKS LIKE THAT. IN STUMBLING AROUND I REMOVED THE 2 CONNECTORS I HAVE REFERRED TO AND WHEN I PLUGGED THEM IN AGAIN AND THE BACK LIGHT CAME ON AND IT WORKED. AFTER A FEW RESTARTS WITH SUCESSFUL RUNS A SMALL SPARK AND A LITTLE SMOKE APPEARED FROM ONE CONNECTOR. I REMOVED IT AND THE PLASTIC AROUND THE CONNECTOR WAS A LITTLE MELTED. I PLUGGED IT IN AGAIN GINGERLY AND IT WORKED THEN SOME MORE SMOKE. I THINK THE PROBLEM OS THE CONNECTOR AS IT DOES NOT LOOK AS IF IT IS GOING IN TO THE PIN BUT BESIDE IT. SO NOW I'M GOING TO REPLACE THE CONNECTOR (IF I CAN FIND ONE) ANS SEE WHAT HAPPENS.AT LEAST I KNOW IT WORKS. AND FEEL I'M ONE SREP CLOSER. DO YOU HAVE ANY WHERE I CAN GET THE CONNECTORS? THEY ARE REAL SMALL.
    THANKS

  • dondjohnson Jul 26, 2009

    WELL, GOT THE CONNECTOR ON AND IT SEEMS NOTHING HAS CHANGED. I DON'T KNOW WHY IT WORKED FOR A WHILE. THE PICTURE BELOW IS OF THE POWER SUPPLY. ITEM 1 AND ITEM CONNECT THE 4 WIRES THAT GOES TO THE BACK LIGHT/DISPLAY. ITEM 1 WAS THE CONNECTOR I HAD TO REPLACE. THERE IS A BLACK WIRE ON THE LEFT AND A BLUE ON THE RIGHT OF THE CONNECTOR THAT GOES TO THE BACK LIGHT. I PLACE A METER ON THE PIN THAT HAS THE BLUE WIRE AND THE POWER CYCLES AT THIS PIN. WHEN ON THE DISPLAY LIGHTS. WHEN IT CYCLES TO OFF THE DISPLAY GOES OUT. THE VOLTAGE READ FROM 9 VOLTS AND GOT UP TO 30 VOLTS AT ONE TIME BEFORE IT CYCLED OFF. I DON'T KNOW WHAT TO DO NEXT. FYI THE MULTI PIN AT THE BOTTOM OF THE BOARD CONNECTS TO THE MAIN BOARD THAT HAS ALL THE TV ELECTRONICS. ANT OTHER IDEAS?
    THANKS FOR YOUR HELP



  • dondjohnson Jul 26, 2009

    YES I'VE LOOKED AT BOTH OF THEM UNDER A MAGNIFIER AND CAN'T FIND ANYTHING. I THINK THE PROBLEM IS ELSEWHERE. I HAVEN'T LOOKED AT THE MAIN BOARD WHICH I MAY DO TOMORROW. IF I CAN'T FIND ANYTHING A MUCK I THINK MY NEXT STEM IS THE RECYCLE BIN. I HATE THAT BUT BECAUSE ALL IS OK EXCEPT THE LIGHT GOES OUT. THE POWER CYCLES OFF EVEN WHEN NOT CONNECTED TO THE BACK LIGHT/DISPLAY,

  • dondjohnson Jul 26, 2009

    I THOUGHT ABOUT BUT THE POWER CYCLES WITH THE BACK LIGHT DISCONNECTED.

  • dondjohnson Jul 26, 2009

    I THINK YOUR RIGHT.
    LET YOU KNOW HOW THINGS GO/

Well either the backlight or the backlight inverter is the problem if you can see a picture by shining a flashlight on it like you think. Usually it is the inverter with this tv. You can order a new one through this number 1-866-289-5168 which is directly through the manufacturer since many online sites won't carry the parts. Let me know how this turns out.

    Its not a board, its an inverter that powers the back light that is bad on this tv unless you are getting no voltage to the inverter for the backlight. Have you checked this?

  • Benjamin Patri
    Benjamin Patri Jul 25, 2009

    The inverter will be directly wired to the back light. The back light will be located on the side of the screen and the inverter should be right next to it.

  • Benjamin Patri
    Benjamin Patri Jul 25, 2009

    Have you found the backlight? It will be on the side of the screen. Normally, the backlight is mounted along either the right or left side of the panel (screen) on the back. A service manual I can't provide as those need to be paid for due to copyright reasons and are quite expensive. An inverter will look like the below image.

    Go to a local radio shack and take the tv with you or just the connector and they can match it up with a new one.

  • Benjamin Patri
    Benjamin Patri Jul 26, 2009

    Have you found any broken connections on this board? How about the capacitors, I can't tell for sure from the picture but do any have the tops swelling on them indicating that they are bad?

  • Benjamin Patri
    Benjamin Patri Jul 26, 2009

    You can always have a shop like Radio Shack look at it if you can't find anything, maybe they will, of course it may not be worth it but I'm sure you could sell it for something no matter what. Also look at the wiring going to the backlight and see if the wires are frayed or anything is loose at the backlight itself which may be causing it to flash on and off.

  • Benjamin Patri
    Benjamin Patri Jul 26, 2009

    I would keep looking for a bad capacitor on the boards then and if you find anything, please let me know.

    Thanks for rejecting my assistance.
    Back light inverter is different board, not similar with power supply.

Polaroid TLA-01511C stopped working after electrical storm. Will try to change fuse, if I can get to it. How do I access the fuse? NOT equipped mentally or with tools to do more.


Contact any service technician. The fuse can be located at itw main power regulator board inside. If the power supply regulator board is found faulty, 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 precious time.

Polaroid Tla-01511B LCD TV goes blank after power up. Power led stays on. I replaced all 1000uf and 470uf 105 degree caps, no luck. What else should I replace?


have you been tried to dis able the supply going to the inverter board for the back light which may have bad parts causing the supply to drop. by the way is there any blinking lights after it turns off? it will tell you the error either in the power supply, inverter board or at the main board.

The power is on; but the screen goes blank (black).


I cannot say enough about this particular brand. The biggest problems are the many electrolytic capacitors in the signal board that go down. You may have a bad cap or two in the power supply. The problem would be in the signal board (Where the RCA connections and RF connectors are). Replacing the caps are very time consuming and the danger of pulling a trace away from the PC board can happen. This may destroy the TV. Just be very careful. Thanks for asking and show a few hands of support!

Radio Shack is your best bet. I replaced two 680uf 10v caps and one 1500uf 10v cap. It now works just like brand new. The caps I replaced had higher voltage values hopefully this will help prolong the life of them.
