Question about Mitsubishi VS-50805 50" Rear Projection Television

2 Answers

Messed up Image

Okay, so here's the problem.  I bought the TV back in 1999 and up until around June I had no problems with it.  Then one night, the video seemed to flicker slightly when I was watching a dvd.  Thought nothing of it, went to bed.  Next day, turned the tv on and here's what everything looked like:

I did some initial research but came up empty handed and only to try a hard reset by unplugging everything, letting it sit and trying again.  I did this and 4 days later (without using it) I plugged everything in and it worked fine.  I didn't use it much over the course of the next few months, but it did this same exact thing twice.  It seems like it'll act like this, then after sitting off it'll go back to normal for a while, then right back to this.

Most recently, I turned it on, everything was fine.  Let it sit with my satelite on for a while, then it randomly went right back to this.  I didn't hear any clicks or pops when it switched back to this messed up mode.

Here's a closeup of the screen:

Some reading makes it seem like the convergence is way off, but I can't adjust it through the TV's screen settings.

Anyone know what's wrong?

Soldering convergence amps is a temporary fix........Since the
labor is about the same,it's best to change-out both Ic's.Your
pix should return to near normal,with minimal adjustments

I just replaced my bulb (XL2400) on my rear projection TV. I go to plug the bulb back into the TV and I get the error (red light flashing) that indicates that the bulb or the door is not securely in place. Is there a trick to getting the bulb back into the proper place. I messed around with this for over three hours last night.

It is worth getting an estimate. From the symptom you explained, it looks like the horizontal output transistor became defective.

Blue wide streaks in my 42" Sony TV model KDFE42A10.

I have the same TV and the same problem and it's also just over 2 years old (bought it June 2006) when the problem started. Every day, I saw the blue streak cover more of the tv, now 6 months later, it has all turned to green and the entire tv has a green tint. It looks like I am watching tv in murky green water.
I am lucky that I purchased the additional warranty on the tv and finally got around to calling them. I hate to tell you this, but they told me that the optical light has gone up and they are replacing the tv.
