Sony BVM-D32E1WU problem

[forin]

Hello everyone I am hoping someone can guide me on how to fix this problem. About 4 months ago I took shipment of a Sony BVMD32E1WU. Due to purchasing a house and relocating my family I was unable to turn the BVM on until last night. Immediately I noticed a rainbow effect around the edges of the screen. This is present in every input and all menu screens. I have a feeling that it took a nasty hit or two either while being shipped to me or when I moved. Everything else looks to be intact, the scanlines are stable and the color in the center of the screen looks fantastic. Hopefully this issue can be corre

Firstly, congratulations on acquiring one of the best monitors ever made.

Secondly, unless there is some physical fault or damage, then this is relatively easy to fix, it just takes a bit of time. The D32's (and A32's) suffer uniformity issues when moved because of the earth's magnetism, probably as a result of the tube size.

1) So the first thing to do is sit the D32 where you plan to have it permanently positioned, otherwise you will have to fix the uniformity issues again when you move it to its final destination. Even moving it across the room or rotating it slightly could be enough to upset the uniformity. These monitors were installed in editing studios, calibrated initially and rarely ever moved.

2) Print out pages 51 - 54 of the D32 operational manual (specifically "Adjusting Beam Landing and Digital Uniformity (SET UP 7) - WHITE UNIFORMITY Menu") and read through the instructions for making the required adjustments.

3) Make required adjustments for all points of the screen (this could take you 30 minutes or more to get right). Perform the beam landing adjustments first, followed by the digital uniformity adjustments last.

You'll notice that the instructions mention a manual mode (done by hand) or an auto mode (using a BKM-14L light probe or a third party probe). If you have a light probe, then the process is a lot quicker, but honestly I prefer doing it manually as I end up with a better result and perfect white uniformity.

Hope that helps!

Do you have external speakers any where near the monitor? Mine looked like that when my speakers were too close.

Just chiming in to mention I experienced just about the same exact issue. Took delivery, hauled it upstairs, fired it up, held my breath for that moment of truth, saw discoloration in a couple of the corners, and proceeded to panic about how it was handled, etc. I initially hoped it was simple interference from something in the room, but the issue turned out to be exactly what xga described. In fact when I rotated the stand 90 degrees the discoloration changed position, it was interesting to observe how the earth really can cause this stuff. Ultimately the landing adjustments fully resolved everything, leaving a pristine uniform picture, and myself thoroughly relieved. Hopefully your experience will end similarly!

On a side note, it made me wonder if these types of experiences have contributed to some of the reputation that the D32 sometimes seems to get for bad tubes, unreliability, etc. It seems to be an often necessary, but likely completely unfamiliar step to most in setting these up. I certainly had no clue initially. Anyways, good luck, let us know how it turns out.

Sshhhhhh!!

XGA, thank you! I will give it a shot as soon as I can. You seem to know a lot about these units, I might hit ya up for more tidbits of information.

tjstogy, the room is empty except for a couple beds. I wish I could fit it in my media room but the damn thing is almost 4 feet deep, it is seriously huge!!!

johndp977 that is great to hear, it doesn't look like there is any damage to the unit which I am grateful for.

Ok this is before white uniformity

This is after 3 hours of work.......

The blue and yellow band do not seem to go anywhere, but the magenta is mostly gone.
The digital uniformity does not seem to do anything that I can see I played with that for an hour or so, maybe I am missing something..

Does this look like a bad set?

After playing some Valkyrie Profile, the areas that are uniformly white look fantastic with stable thick scan lines and the colors just pop. The lady I bought this from said the tubes were replaced and I have to believe her, the picture is so bright and vivid with color. Should I crack the case see if there is any manual alignment? Thanks again for all of the help that has been offered!

That doesn't sound great.

I'm assuming that the degauss function is working correctly when you press it?

I'd only open it up to inspect for any visual damage at this point or unless you know what you are doing. I think very unlikely, but perhaps the purity rings on the neck of the tube have moved in transit.

I'll experiment with my D32 shortly and see if there's something that we're missing.

3 hours? Wow! This screen is just for rough adjustments. I don't think I'v spent more than 10 minutes with it.

It really didn't do anything, not even in the spots where it is white?

Anyway, I just came upon some videos while searching for something else. They show how to demagnetize a CRT. Personnally I have never seen something like that before. Crazy. But it looks a lot like your problem.

That's for simple degaussing of the screen. This issue seems more complicated. A screen that hasn't been degaussed for awhile never manifests itself with the type of miscolored rings that forin posted, but rather with miscolored patches.

Hello,

I think the problem is that you didn't change the "direction" of the monitor. It says NORTH in both of your images and I believe that can be changed.

You should first change that to SOUTH, SOUTHEAST, EAST – whichever will give you the least amount of issues, then you move onto the FINE ADJUST.

I would also suggest you reset everything back to 100, which is likely the default.

You don't happen to have a Sony BKM-14L probe do you?

Anyway, I think this will solve your problem. I have this monitor as well and will subscribe to the thread in case you post again.

Good luck!

Thanks for the help philexile but North was the best setting, i tried them all. I wonder if any crt technician still exist lol.

Try moving the direction that the display is sitting while it is on and see if that changes the picture.

[philexile]

Also, get a compass – your phone probably has one – and figure out what direction the monitor is actually facing. No matter how the picture looks, change the DIRECTION to match and then try doing your adjustments.

Hello,

I spoke to the retired Sony technician, Pat. He had a few points:

1. It looks like you picked this up from Broadcast Store – unfortunately they do not have the best reputation.

2. If the tube was replaced, its possible the yolk/york wasn't seated correctly. He suggested that you open up the top, loosen it, remove the wedges and try reseating it.

That said – I wouldn't dare try this and I've worked on these monitors to some degree for years. This is a delicate procedure, slightly dangerous, and you could make it worse.

3. You said that you moved – could the monitor have been exposed to excessive electromagnetic interference?

4. He also suggested to move it to another area of the house or change the direction that it is facing. Make sure you get a friend (or four!) to help!

Personally, I would try moving it around, but wouldn't mess with anything on the inside of the unit. I would absolutely call and complain to Broadcast Store if you can't resolve this. I'm sure you paid a good bit for the monitor and you shouldn't be put in this situation.

Talk soon

I finally had a chance to sit down and play around with the monitor. Thank you Philexile for all of you help, unfortunately it seems as though the tubes broke at some point during shipping, and now I have a 210lb paper weight. As an old CRT junkie I was rather looking forward to spending some time playing on it, oh well. Thanks everyone who offered advice, I really appreciated it!

I'm sorry but can you send me private message regarding this matter?
