Adjustments Sir, Can the convergence be adjusted without the original remote? Maybe a generic one bought at Wal-mart. If so, please advise. Thanks so much, Les lesfurrow@yahoo.com

On the Akai PT429HD? No, you need the original Samsung, as only it has the button to save convergence settings. I got mine for ten bucks. Without doing a proper convergence your set is kind of wasted, so that ten bucks is worth it. I see the price of this remote has spiked lately, so I'd start with ebay first of all.

If you've tried my convergence procedure on the Akai remote and can find a button that saves the settings (the cursor will blink and then center) then you don't need to buy a Samsung one. The only universal remote that has a chance of doing the job would be more expensive than the real one.

Color adjust without original remote cs-35303


Almost any Mitsubishi remote will work for standard adjustments--just that simple.

If issue is too much red, green or blue(not a good black and white picture) the controls for those adjustments are located inside the set on the board that plugs onto the end of the picture tube.

Let me know what your issue is and I will advise further.

I just replaced convergence chips on my 51 inch magnavox and it looks good, but i have to keep adjusting it every time i turn it on.


If you are adjusting the convergence in the customer menu you will have this problem.

What is model number of the Magnavox and do you have the original remote working for it?

There is a TECH menu for adjusting the convergence all over the screen--part of this is when you adjust there--you hit a couple of buttons and it SAVES the adjustments into the set's memory.

If you have the original remote I can tell you how to enter this mode and save the adjustments---The customer mode will usually give ok results but the TECH should give lasting adjustments.

Let me know and I will tell you how to get in etc.

If this information helps you rate this solution as I do this here for free---I am here to help people.

My convergence is fine but after professional replacement of the board there is a slight bowing and slanting of in-screen borders and some channels have a little distortion at the top of the screen. The...


First: If the convergence board was replaced--the set may need a total adjustment---this is why most good techs replace the convergence chips and any bad parts instead--also costs less----Second: to enter the service mode (it is done with the set already turned on) should be Mute, 182 or Mute 183---if you get the convergence mode--7,8, 9 will select red, green, blue, 5 will stop the cursor from blinking and allow adjustment---with the cursor blinking 2,8, 4, 6 will allow you to navigate---depending on the remote used--the P mode button will take you across the screen in a series of steps--the remote I use for this has a button on it marked data save--this saves the adjustments. Your remote may have it or a different button for this.

Understand---if you get into the convergence mode---Green determines if the geometry of the picture is straight---red and blue are adjusted to it---to align the green you need to call the convergence mode up and then cover the lens for the red and blue---leaves you with a green grid---then you need to select green and wherever the grid is not straight adjust it--once you get it straight you need to uncover the red and adjust it to the green, and then the blue to the green---green alignment determines if the picture is straight---It sounds like this guy did not try to get the green straight and just adjusted the red and blue to whatever the green was.


My point here is if you paid money for this repair--either he aligns it straight or you should get your money back----GREEN never needs to be adjusted unless the dcu(digital convergence unit that stores the adjustments) has been replaced or the Convergence module has been replaced---I bet if the original convergence module was repaired(chips replaced etc) and installed you would not have this problem.

If the guy replaced the DCU then GREEN must be fully adjusted for a straight picture FIRST! then red and blue adjusted to it.

It is not easy or quick to Adjust the green--maybe he just wanted to get out the door?

I do this here for free so if this has helped you take a minute and give me a vote here.

If you have any questions or need help reply to this post here.

Call your store manager and if that doesn't get you action then call 1-800-WALMART and ask that the District Manager be advised and that you expect a call back. Wal-Mart should stand behind anything they sell including warranty. I purchased one for my new notebook and dealt with the store manager for information on the warranty before I bought it. The manager will respond.

Pt5598hd convergence


I purchased mine about 5 months ago. Ive been researching and playing around with the remote. This will help you on the way. With the set off, press "Mute", 1, 8, 2 then turn the tv on. This will bring up the main settings, dont change any values on any page, unless you write the origonal values down first, because the total reset doesnt return everything to a "factory" preset. Scroll down to reset and press the enter key. I havent come across any owners or service manuals, and support is slim to none. I wrote a review for the same model on a wal-mart site I believe, and it explains adjustments in more detail. If you want to try to figure out the buttons for yourself, while the tv is on, press "Mute 1, 8, 3" this is another set of adjustments for finer detail. If you change an adjustment here and your not sure, just press the exit button. To save your adjustments in the convergence mode, press and hold the enter button, it should flash a few times and center itself on the screen. If you make a mistake in this mode, the total reset I mentioned first should get you back on track. If you find anything out or have a question, feel free to write me at Silverado1st@aol.com This is a nice TV, wonder why they stopped making them.

Convergence without a remote


First off, you do need the original remote to adjust the convergence, Second, the service mode will not fix your problem. If the colors have all drifted, you have a problem in the convergence drive circuit. Most likely the convergence IC's are bad or going bad. The service menu is not a fix all for the problems with the convergence. The service mode will or can make minor convergence adjustments,not anything where all the colors are off. If you have no solid state repair experience, call out a service person to assist you in this repair. Good Luck
