Question about RCA L37WD12 37 in. LCD HDTV

1 Answer

When I turn my L37WD12YX1 tv on. It takes a few minutes for the green light to come on then several minutes later the back of the screen lights come on then several minutes later, I can unplug the power cord and it comes on and works fine until I turn if off for the night. I had the only TV repairman check it and he said that the power board was bad. He tried all of his supply people and said that it was not available. I finally found a company in Calif that told me that they could repair it if I sent it to them. Well to make a long story short, I sent it to calif and spend 150 dollars and still have the same problems. Could someone please tell me what i need to get this tv fixed?

    This is a very small town. I wish that I could just get someone to sell me the needed parts and send them to me. At this time, I cannot walk alone. I broke a bone in my back and have to be rolled ROUND. where could I get the part numbers without takeing the board out until i am ready to fix it. it will be no problem for me to fix because i have owned and operated my own auto repair shop for the past 40 years and i did all of my own alternator repair so soldering parts in nothing at all for me. thanks in advance, charles

    I got the board out today. it is just like the picture you sent. I carried it to radio shack and they tell me that they do not carry or order these parts. Looking at the one close to the side and reading left to right. BLUE RED BLACK GOLD. THE ONE IS THE MIDDLE BROWN GREEN YELLOW if there is a fourth stripe, it is going to be the same color brown or gold and the. I really do not think there is but three stripes on that one. On the little round things, the one in the middle has 85 C right under that it says U 3 On the other side of that same one it says 63 V them something that icannot read. the one at the side says 50
    v then on the other sise is says ?0606 then something that I cannot red. If you can please tell me where I can buy these or I will mail it to you. let me know what I can do. Blue os saysREA 85C H614{M}

    I was able to get the tv repair man that had the tv to start with to change the parts you pointed out. I did not get it seT back up to connect the wires until this morning. You were right on what you thought was wrong. It is just like it was when it was new now. THANK YOU SO MUCH, CHARLES FORTENBERRY IN MISSISSIPPI

  • clarryf Oct 09, 2010

    He was right on the first try. it took me a few days to get someone to make the repairs made because this is a very small town and I am not able to move around or pick up anything because of back surgery 8 times. I am so very happy with this gentleman that helped. This is what was wrong from the start and I did without my big tv for 3 months doing what the only tv shop here told me that was wrong. How wrong he was and how right your guy was. Thanks so much Charles Fortenberry in Mississippi

Hi,
Question details gives idea that standby power supply board seems cause of problem, tv has two power supplies, one is standby power board as shown in below image and other is main power supply board that is bigger in size.
I guess you sent out main power supply board for repair that did not make any difference on tv problem.
Check out following image of standby power supply board and replace marked capacitors and resistor carefully (5 parts) if you do it yourself or ask local repairman to fix it.
Standby supply output voltage seems lower than requirement of tv and causing start-up problem. These voltage goes to system control chip that controls other functions of tv and standby volts must be stable and accurate to turn On tv properly.
I hope these info will solve your tv issue.
Thanks.

    You can buy replacement parts in Radio Shake or any other spare parts shop in area, just take out little board from tv and take it with you to show them for required parts.
    I'll try best to assist you on site.
    I'm afraid, experts are not allowed to provide personal contact info over Fixya.com
    Thanks.

    Sorry to hear about your health, my best wishes for your smooth and quick recovery.
    Let me explain one thing, lcd tv boards are not suppose to be repair on component level as per manufacturer advise/ policy so there are no part numbers of these components, all is needed to read out capacitors value that would be written on them and check its availability at partstore.com to order it.
    Let me know color rings on two marked resistors to give you its rating value. post color rings in sequence as you see it on resistor like gray-red-black-golden like that
    Thanks

    BLUE RED BLACK GOLD. = Colors would be Gray Red Black Golden and resistor value is 82 ohms 1/2W

    BROWN GREEN YELLOW = This one is valid color code that shows resistor value 150K ohms 1/2W, this one is most suspected resistor for your tv problem.

    You can get these resistors from any junk circuit board, just make sure color rings combination must be same, replace them to fix your tv.
    Regarding capacitors, I hope these would also can be obtained from any junk circuit board of tv or any thing similar.
    You need three capacitors and two resistors. I have lots of these parts in my repair-shop but I'm far away from you (Pakistan).
    :)

Tv cuts off and green light flashes


If your set was manufactured around July 2005, you may need a firmware upgrade to solve this issue. On the Sony website you can enter your model # and serial # to see if you TV is affected. If so, it is easy to have done and may be free from Sony. It sounds like the issue they described in the writeup on the required formware update. I had mine done within few months of when i bought it (purchased in Dec 2005) and it has been working flawlessly since.

Good luck!

Tv cuts off and green light flashes


Yup, it seems a lamp problem can give a blinking green light over the 10 times (1 - 10 times for diagnostic codes), but in my case rather than replace the bulb if it works for a minute then resets with the green light blinking, do what I did.
Take the lamp out and inspect it, it has breather screens top and bottom, if it cant breath because there clogged with dust, clean them, and you can remove the screens, use q-tips and clean the inside. I saved the cost of a lamp and it's working fine!
