Panasonic PT-47WX53G Convergence Problem - board replaced still does not align

Developed a convergence problem, ordered the manual, tried to align, would not align, replaced the dc-board p/n tnpaa120 board and it still will not align. Any help would be appreciated.

    I tried what the factory service manual said to do, i guess it is manual convergence, I did the course and the fine adjustment. I could not do the Raster setup as I do not have the Eprom jig or the TU-DST51 set-top DTV decoder box. Another note, the green aligns to the templete but the Red dones not align to the green. I think the blue has that same problem also.

Hi,
First start by verifying your TV is plugged directly
into a wall plug, no extention cords and no surge protectors.If plugging into the wall stops the shutdowns then
go out and replace what ever cord you were using.otherwise you need a TV tech to look at the TV,the problem could be in many places in the TV where convergence IC may be failing
135 volt supply to the horizontal sweep could be low
almost any low voltage supply could have a cracked
solder connection causing random interuption,also I recall nuisence shutdowns with that Model from the CPU PCB being loose.Left side of chassis all the way to front of PCB
its a small PCB that docks into signal main PCB
and it has 3 plugs that fit into sockets and it does
get loose over time (heating and cooling).What I would do would be unplug the TV then remove and remount the CPU PCB..Thank you!!..

Unfortunately your best bet is to have a professional take care of it. You tried manual or auto convergence? Was there any change? If you need any help contacting a professional I will be glad to assist you.
Thanks,

    It still sounds like you should leave it to the professionals. How much money is your time worth? You can have it done right without the headaches. You can call around and get estimates as well.
    Thanks,

Yellow band on bottom of PT. Double image on news scroller at bottom of PT. Have tried convergence - no luck. Green will not align and will not come down.


Ur tv have any colors lines R,G,B mis alignment,have colors shadows pictures or 3D pictures.Ur tv convergence board the 2 STK convergence ICS and some or all it resistors are dead.The parts,must be replaced on the tv convergence board to solved the tv convergence picture problems.The shop,will cost u like $300-350 for parts and labors.

PT-47WX53G. TV got moved. Unable to move blue


The convergence ICs have failed which is very common when the set has been moved as a wek IC wont allow the color to be moved. You can get the PT52WX53G convergence repair kit from www.tvrepairworld.com which is the correct one for your model. The kit contains the parts and the CD with repair instructions.

Pt-47wx53g has red ghost. I tried adjusting convergence but some will not adjust


You have a problem with the convergence output IC's. They need to be replaced. This is a very common problem with all projection tv's as those IC's are high current components.

PT-47WX53G green convergence and wave on bottom of screen


Had same problem with Red. Could not adjust. Funny broken lines. Found this link:

http://cmpalmer.blogspot.com/2006/11/fixing-my-own-tv-part-ii.html

Replaced the ICs. Was disappointed at first 'cause it was still all bowed out, but then realized that the Convergence 2 "target" can be changed with the number keys. Working thru 1-9 and going back to readjust as necessary adjusted each one into perfect alignment.

Problem solved. TV works great.

I should add that while I am reasonable technically adept, I am a software geek and never soldered before... hardest part was getting up the courage to dive in and do it myself. Glad I did.

Panasonic PT-47WX53G Projection TV - convergence problem, can not align completely


I don't know why that guy told you to replace your "DC" board (that is the one you mean, right?) More likely than not, it's your convergence amp integrated circuits (ICs). I had what I think was the same problem (on the same exact model TV) you described, and I looked around alot of blogs and DIY websites, and this seems to be the most prevalent root behind these convergence problems. I ordered the two chips for twelve bucks (for both), spent a few extra bucks (like $35) on some electronic tools / solder supplies, and followed procedures laid out here at http://cmpalmer.blogspot.com/2006/11/fixing-my-own-tv-part-i.html, as well as paying strict attention to the service repair manual (which you said you already have?). The result? No more convergence problem, and I saved myself around $400 - $550 over having it done by a professional.

Seriously-- I bet this is the culprit. Just make sure if you're gonna do this that you FIRST check the six resistors (located at spots D-7011 thru D-7016) to make sure there are none burnt out / opened. It may be that one of those is fried also / instead. Since they are far easier to replace, it's good just to rule them out first.

And by the way, just FIY, when I did this I had kept the TV unplugged for about two weeks first, cuz I wanted to make sure all the capacitors were discharged and safe. Did I need that much time? Maybe not (some have said a few hours is sufficient), but I was also primarily concerned about the Flyback Transformer and its wires, which have the highest voltage (up to 30,000 volts) and can hold a charge pretty long. And I'm still here to write about it. So, check out the link, and see if you'd like to try this yourself, as well!

Just bought a PANASONIC PT-47WX53G On ebay for what I thought was a steal. It was explained that somehow someone got into the service menu and messed something up with the convergence on the green gun....


You can try restoring to factory defaults, and you can try the manual convergence option. If the manual convergence fails to reset (as in, the crosshairs physically will not move), then the convergence board is bad, and will need to be replaced or repaired (if you are a good circuit solderer).

Convergence


It's a possibility that this board may be at fault or it is also possible that the convergence amplifiers are drawing too much current and shutting the unit down. This may require replacing both IC's along with a convergence touchup, or as you mentioned, it may simply be the job of swapping the Digital Convergence board PN TNP2AA120S.
