I just moved third floor to third floor and tried everything in my power to get the TV back the way it was.. I manually adjusted the focus, tried the focus pots and have done the convergence at least 3 different times, all to no avail.

The corners are wayyy off and the TV just doesn't look Hidef any more.

A couple more...

Helps to post the model number & brand. Last pic, looks like a Philips/Magnavox? Did you only do the user level convergence, or have you done a service menu convergence? http://www.keohi.com/keohihdtv/brandspecific/philips/philips_convergence_geometry.html Also take the screen assembly off, clean the optics and take a look down into the lenses... With the Tv on, do you see a nice clear picture down inside each crt, or is there cloudy gunk floating around in there?

Hammer

oops..

It's a Mitsubishi WS65613, I believe that is the 2005 model. I already did the service menu convergence, the regular 64 point as well as the pot focus adjustments behind the front speaker panel and the manual focus at the gun.

Right now, I am inclined to believe one thing, when I focus for the middle of the screen on either the focus pots for each gun, the middle gets good and the sides get blurry. When I don't focus for the center, and focus for the sides, the center is obviously blurry.. I just don't know what to do here..

The TV doesn't look one bit of Hi-Def and my ISF tech is not going to be here for a month.

If this happened with my CRT RPTV I'd try to pinpoint whether the move physically shifted the lens, mirror, or screen-elements spacing. Just speculation, but the center/side focus-blur problem suggests that--or screen-elements warping. Covering the blue/red guns and injecting a crosshatch, or using the service convergence grid, needs a sharply focus green pattern over the entire screen to start. Once that was achieved I'd uncover the other guns one at a time to check whether any of them aren't similarly sharp over the entire screen. Movement might also have shifted the deflection yoke on one or more CRTs. -- John

Stupid question.. What are screen elements?

And, is it "fixable"?

What are screen elements?

The Fresnel lens sheet (innermost), lenticular lens sheet (middle), and usually an outermost protective sheet--all with spacing material to ensure they're parallel with each other. Seems that shifted/missing/compressed spacing might cause one or more elements to become warped, blurring focus only on certain screen areas. Newer designs may use very thin films for some lens functions compared to older, thicker plastic sheets. -- John

Hmm.. and what would I do to straighten this warp out, because from just the feeling on my fingers up against the screen, I have a feeling that is one of the issues.

When adjusting convergence, what do I work on first? center to edge? edge to center? I have tried a little of both and with mixed results.

Haven't tinkered with my screen with ~7 years use, so others here might offer better tips. But if focus was fine before the move but not after, it seems best to figure out what may have been mechanically shifted during the move--from screen-element spacing to a CRT tube to the electromagnetic yoke on one or more tubes, etc.. If it's the screen at fault, isolated from the hazardous high-voltage section, they can be removed and studied for faults. Maybe too much pressure was applied during the move, messing up the spacing. Electronic convergence is interactive over the entire screen, with adjustments in one area also influencing distant areas, so there a certain amount of back and forth. But it reads like there's something mechanically off with the optics, which includes spacing of everything (CRTs to screen), that needs fixing before convergence is attempted. -- John

Well, the ba*t*r*d* moved it one step down at a time letting it fall on each rung of the stairs.. I don't even want to know how much pressure they put on it.

The TV by spec weighs 333lbs. Gregg Leowen is coming to fix whatever he can but I just wanted to make it watchable for high-def for the next month.
