Pvm troubles

[angryswede]

I recently picked up a pvm 14N2E to use as a reference monitor. However, the screen looks like this:



And this:



I've tried to navigate the service menu but it's all in hex values. I've included it in the bottom of this post if anyone is familiar with the values.

Is this something that can be corrected through the service menu or is it failing hardware?
If it's hardware failure can anyone give me a clue what to look for?
I have the user manual which tells nothing and the closest service manual I've found is for the 14L1.
All tips are welcome!

Edit:

This is the endless service mode options, sorry for the wall.

It is your typical geometry problem, easily fixed by way of service menu. I believe another thread mentioned how to restore factory setting using the blue only and degauss buttons.

For now go through every service menu option, remember what the default value was then screw around with it to see what it does. Eventually you'll find one that can be used to make the picture edges concave or covex.

how to restore factory setting

Wait, aren't the specific factory-set settings for geometry and so on only saved in the menu setting, without a fallback "default" (since for many options there is no model-specific default; it can depend on the specific unit) to hit if you mess it up and forget what they were set at? Don't get me wrong, the advice about writing down the settings is good, but I'd emphasize that first...

I am curious what the "h sexy pin" adjusts.

My CRT image quality could certainly stand to use a bit more "h sex".

But yeah, save original values before fiddling. Stay away from any option mentioning R, G or B or pos, size or chroma.

You might want to play around the anything with the word pin in it as they usually adjust geometry. Also put some sort of grid pattern on the monitor before you start adjusting.

That's not a typo either, it's actually there in the menu. I'll see if I can figure out the function.

Thanks for that clue, that narrows it down.

What about the white ghosting after the text lines on pic 2, is that also geometry related?

The Sexy option adjusts slight bowing on the middle area on the edge of the horizontal picture >[ ]< on my PVM M2MDU.

[kamiboy]

Does the ghosting look as bad in life as it does in the picture?

I'd say the source is at fault but that is the unit menu, how strange. Try lowering contrast and brightness. If that does not help, which I bet it wont, your last bet is something in the service menu. I've never seen anything like that so I cannot help narrow it down.

By the by, have you degaussed the unit? If not the do that first.

Hey angryswede,

Bit of a tough one to find but Manualsparadise carry the service manual for the 14N2:

http://www.manualsparadise.com

Comes at a cost as in most cases though it's probably worth it!

[fagin]

First off, it's hard to tell what your issue is, without the aid of a test grid. It appears that it may be a pin cushion issue - to me it looks like it's bowing from the top.

Trying altering 52 & 54.

[fagin]

The ghosting is too much contrast and brightness.

[angryswede]

Thank you guys for all the tips! I'm amazed that these old monitors still have this kind of know-how about them.

Does the ghosting look as bad in life as it does in the picture?

Well kind of. It was hard to capture on camera so I've exaggerated the contrast and brightness in editing. But it still looks like the pic in life, but without the high contrast and brightness.

I don't think I have a degauss option on the unit. I've been thinking of getting a wand/coil for future use though.

I've seen some other places that sell it as well, but all the sites look so dodgy. Is manualsparadise reputed? It's a great service, but if any one needs a future copy they are welcome to write me instead of shelling out $10-19.
I also translated a french copy of the users manual with acrobat's ocr and google translate. It has some typos but if anyone needs it it's better than nothing.

Yeah I know, I didn't even have any source to plug in so the menu screen was all I had to show. I'll load up Artemio's 240p tests with a genesis and try to work it from there now that I've got some clues what to look for in the menu.

Thanks again everyone!

Manuals paradise is safe from my experience. That is where i found the 14L2s service manual at the time since nowhere else had it...

[22point8]

From 1454qm service manual:

[NWrain]

I am also having PVM geometry issues. I don't have a Genesis or Sega CD, so I cannot use that specific 240P test suite. What other methods are people using to input a test grid?

What other methods are people using to input a test grid?

A very simple method is to hook up a PC that does TV out to the display (through s-video or composite), set the desktop image on the PVM screen to a test grid making sure it fills the entire desktop area, and proceed fine tuning the geometry, switching between PAL and NTSC signals from the PC if required since most monitors store separate geometry settings for 50hz and 60hz.

Geometry settings will be identical from 480i to 240p, and from 576i to 288p so you should be good to go...

Have been doing this using my old macbook through s-video, works a treat.
