Question about RCA D61W20 61" Rear Projection Television

1 Answer

Which board is it?

Which board is that? I paid for the premium service, and they told me to change the STK IC. They couldn't tell me where to find it or which one it is. I've just been all through my unit and I don't see anything labelled STK. I have 2 boards which are easy to access. One is SRS-310 and the other is YPRPB-130 AV5. Do either of those sound close?

    I accidentally started a new thread. I meant to post a comment to a different posting where you had told me it was a convergence problem. The specifics are:

    I have an RCA 61939 61" Projection TV that has a convergence problem. Quite a few months ago, we heard a snap and the TV shut off. It came right back on when we hit the power button, but it is bowed in on the top, bottom and sides. We can't adjust the green convergence, but have adjusted the Red and Blue so it doesn't look 3D, but there are no straight lines on it.

    I'm capable of performing board swaps, etc, but haven't seen any references to what to change. Can you help?

    Thanks in advance

    Update, I went back in and wrote down the part number for every board and then looked for chips labelled STK. While doing so, I noticed that Resistor R14512 is cracked and turned white. I can only tell that the first color is Brown and the last color is silver.

    Can anyone tell me what value this should be? I think I'll start by replacing that.

    It appears I have a 15888420 convergence board. I can't find any STK chips. Where can I obtain a new one or get this one rebuilt?

The red color stops working. If I tap the convergance board it sometimes pops back in.

If ws55807 it is not bad connections on the middle board where the two STK-392-570 convergence chips are.

I have seen this over 100 times in these sets. What happens is the pins break loose inside the chips----I have had ones where I unsoldered the pins and some just fall out--only the solder trying to hold them in.

The good news is Total parts cost for the repair on EBAY (I use a seller there) will be about 15 for the two chips and should be under 30 total for everything needed.

I also have start to finish step, by step instructions for this repair in this model---tell you everything you will need and the best way to do it.

I will attach a photo of a typical convergence IC---yours are up front on the middle board facing the front of the set.

If this information told you something you did not know, rate this solution as very helpful as I do this here for free.

P56938 Convergence Problem

I've found some this i nfo that could help you troubleshoot your TV.
Your problem is likely to be in the convergence board power supply
p/n 250868. May not be supplying the - and + 15 volt supply, abd the +45
volt and - 45 volts account shorted diode cr19710. p/n 164590. also replace
cr19709 the one next to it same part #. Also if stk730-130 is bad it can
cause this problem. Also check r 19703 (750k 1/2watt) may be open,
q19700(bc457)or nte123a could have base emitter open.

Yes, I am in Texas, just moved there from Michigan. Got away from the cold just in time. It's beautiful in Colorado, but just too cold for me.

I had no idea you had paid for a premium service. You contacted me thru the free forum. If you would like for me to get the payment for the premium service, you could contact fixya thru this email ( ) and tell her (Lauren) how you did not get the information you needed from the premium question you asked and would like that credit to go to me. She will know what to do about it. I really don't know how you would go about it. As it stands right now, you will end up paying whoever answered you first unless you gave somebody a FixYa! rating and accepted the solution. Unless you request a refund. Which is what you may need to do. I hate to see some other person get paid for my knowledge. This has happened to me on many occasions. I get contacted thru the free forum to solve a problem they have paid somebody else for. I don't spend a whole lot of time on the site, since almost everything I do on this site is free help.

In the premium questions you should not give anyone anything but a "Thanks for Trying" unless you are satisfied you have received the help you have paid for. I never seen a link to the premium question you paid for, so I never got a chance to answer you there. I am sure that some of the answers you were getting there were very amusing, to say the least. As I told you in my last post, I really am an expert in these receivers and I don't believe there is another expert here with the experience actually repairing them as I have. There is a decent bunch of folks working here, but many are not really the experts they claim to be. It can be a pretty frustrating activity using the premium service because there are so many so called "Experts" that are only in this for the money and try to answer questions they know nothing about. I hope it was not as bad for you as I have seen in many other cases.
