Question about Mitsubishi WS-65819 TV

3 Answers

Intermittent convergence issue became permanent

In the last couple of weeks the convergence of the WS-65819 would go way out of whack and then return by itself. This happened several times and now it appears to be permanent. I believe other posts have pointed to the STK392-570 convergence amplifier. Before I order parts I would like to get a service manual. What web site would you recommend? I have found a full service manual offered by User-Manuals.com for $14.99 and was wondering if this is a good site.

    Ordered a service manual from them 2 days ago for 14.99 for a Panasonic. Never received it, but my card was charged. They will not return my e-mails asking them to credit my card. I get the feeling I've been had. The TV was fixed with one sentence of directions from dlplampsource.com. He said "the bulb is hidden behind the silver trim on the front of the TV." That is all it took.

Hi Ed,

Your convergence amplifiers are definitely bad. The user manual will not work, since it is the same manual that comes with the set when it was new. The service manual can be found at:

P.S. Thanks in advance for rating me!

Have a Mitsubishi WS-65819 (about 9 yrs). over past 3-4 weeks the color started to skew (3D like arch on top and bottom), then yesterday, the TV totally powered down and will not power up, totally dead. ...


You lost your convergence IC's and possibly a resister or two that are in the same circuit. If you are good at Soldering, this should be somewhat of an easy fix. I believe you can still get the IC's for this set.

Turns off as soon as I turn it on. ws - 65819


I had the same problem. The repairman said the Convergence ICs were bad, located on the big aluminum heat sinks on the center board in the TV. He replaces both, and a couple of fuses (that look like resistors).

The tv worked fine for a couple of days then did exactly the same thing. They are coming back out to fix it next week. If there is anything different, I'll post an update.

You likely have bad convergence output ic's type #STK392-570.  These can be purchased at UED 800-648-6657.  You will need to remove the board they are mounted on to be able to usolder the old ones and resolder the new ones.  These will be mounted on heat sinks.

Bowlike effect convergence all screwwed up


I suspect you originally had an intermittent solder connection on the convergence circuit board. This may have damaged the convergence IC's on that board by now if repairing those connections doesn't fix the set.
