Convergence drift My HCN653W is about 2 years old. I find that the convergence drifts, so I bring up the crosses and reset the convergence, I save the settings and the picture looks perfect...for a couple hours. After a couple hours the convergence is off again--way off. It seems to happen in random spots on the screen, in varying degrees...but it's always significant. I've never had this problem before, it only just started.

Its a convergence problem. The three color guns have drifted and it shows on the edges. Typical of an old projector tv
These will help

Normally on the RCA rear projection TV's you would bring up your menu and choose the Setup menu, then press OK on the remote. That menu would then have Convergence as a choice. Once that was chosen the next menu would give you the choice of either letting the TV run it's own Autoconvergence program, or you would select either Red or Blue convergence.

Choosing Red Convergence would bring up a Yellow cross-hair in the middle of the screen. If the Convergence was not correct you would see separate Green and Red cross-hairs. Once they were perfectly aligned you would again see one Yellow cross-hair.

Choosing Blue Convergence would bring up a Blue cross-hair in the center of the screen. If the alignment was out you would see 2 Blue cross-hairs. Using the Up and Down and Left and Right cursor keys you would adjust the alignment until a single solid Blue cross-hair was in the center of the screen.

need replace convergence ic chips to resolve this issue, parts cost about $40

The Tvrepairkits.com to buy a convergence kit,will fix ur red color line or color shadow pictures drifts problems.But u must have tools like a soldering iron,a desoldering pump or a roll of desoldering braids,a roll of solders,also can u do basic soldering skills work,than u can fix this problems.Yes,the new tv design have Energy Star incorporated in it design and will save u energy and some money,but the power consuption of a big screen tv any century era,still will cost u alot of money to operate it.

I finally just was able to solve this problem! I saw somewhere that someone had made sure their primary mouse was selected under hardware, which got me thinking. I thought I had seen a second mouse option somewhere. So, I went into my Control Panel > System > Device Manager and click the arrow next to Mice and other pointing devices. Sure enough, there were two listed. A seemingly generic one and my Logitech I've been using. I right clicked on the generic one and chose disable and the drifting IMMEDIATELY stopped. I went so far as to re-enable that generic to see if it was a fluke because it had stopped drifting on its own yesterday, nope as soon as I enabled the generic device, drifting started again. So Happy!!!

Bad chips or faulty soldering....

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

Go Ahead. Use Us.

Your tv is crt-based and is out of convergence. In other words, the settings for keeping the Red, Green and Blue images aligned have drifted and must be reset. This is common with CRT projectors and CRT rear projection tvs.

Refer to your owners manual for instructions on re-aligning it.

you are going to need to replace the convergence board assembly. It is available at http://www.samsungparts.com/part_detail.asp?catalog%5Fname=Parts+and+Accessories&product%5Fid=BP95%2D00142P&search%5Fmodel=HCN653W. Also get the service manual, as you will need to do some touchup convergence and reset the perfect focus setup again If you have the technical ability. If you do, great! If you do not, these service menu alighnments can mess up your set, so take no shortcuts. Good Luck
