Question about Zenith R40W46 40" Rear Projection HDTV-Ready Television

1 Answer

Same old red convergence issue

I also have the same old problem of red arcs going across the screen on my Zenith R40W46. I have read the previous postings concerning this issue and have located the circuit board with the IC's and resistors. Nothing seems to be discolored or wrong to me. Is there anything else I should be looking for to identify what the problem is? Thanks in advance for your response.

    So, I bought new and replaced the convergence ic's and now have a blue convergence issue. What did I do wrong!?

  • winterst81 Jun 26, 2008


    Thank you for your time and patience with me and everyone else on this forum. I will double check the solder connections for any bridges and let you know. I don't know what you mean, however, when you say the resistors are open. Does that mean that they are physically busted or just discolored? If I do have a couple resistors that need replaced, will it harm my new IC's to have the TV running with the bum resistors?

    What do you need to check for resistance?

    Thanks again for all of your help! I'll let you know how it goes.

They wont show any signs of being bad if you cant adjust the convergence the ICs and possibly a few of the convergence resistors will need replacement. You can get new ICs and resistors at the following link and they come with free instaltion instructions.

    have you double checked the solder connections on the IC pins for any possible bridging from solder, also did you check for any open resistors cause often the resistors will need a few replaced along with the ICs.

    Yes if the resistors are open it can wear out the new ICs very quickly. What I mean by open is a resistor can actually be burned on the inside without any visible sign on the outside such as discoloring, the only way to tell is by unsoldering one side of the resistor and lifting that end out of the circuit then checking it for resistance a open resistor will not have any reading what so ever and will need to be replaced with the same rated resistor. or if the resistor reads more or less than 5% of its rated tolerance it will need to be replaced as well.

    Just a regular Ohms meter analog or digital. digitalis better Radio Shack has them they are very inexspensive. Walmart also has them available.

The televion has started showing a blue and yellow douwble vision on the bottom of the screen?

Have you tried going to the service menu?
Do this by holding "MENU" on the TV set while it is on, then pressing "Menu" on the remote. You may have to do this a couple times for the menu to appear.

There should be a option on the appearing screen for Convergence, which has more options the the standard menu. To work this under the "9" setting for convergence, each of the + on the screen is the corresponding button the the TV remote (3 if top right, 5 is center). Use your volume or arrow keys then to move the selected + in the desired direction.

Use the [TV/Video] button to switch which color you are aligning, trying to align Red Green and Blue so they overlap, making white.

Good luck!

Zenith red convergence problem.

yes thats the right board if those two resistors are open the convergence ICs will need to be replaced as well. Its an easy repair. Heres a link where you can order the parts and recieve free installation instruction. If you need me to post the STK numbers and values of the resistors

Your convergence amp ICs are bad. You will need to replace both of them. Its an easy fix if you can solder. Check the resistors right next to the ICs also often 1 or 2 of them burn open when the ICs go out. Let me now if I can assist you further.
