Help a newbie to enjoy his good old CRT? :)

Post by Antiriad »

Hi everybody,
at first let me say that, despite not being a shmups-addicted (still), I like the forum because there are a lot of opportunities to learn something... so, REALLY, thank you for all.

For my retrogaming room (Neogeo CMVS and PS2 via RGB SCART) initially I was searching for a Sony PVM or a Beovision MX, but I finally decided to enjoy what I already have: a Sony Trinitron 29'' KV-29xxxx (can't remember at the moment the product code). Since my father bought it to me, I always liked the picture of this TV, nevertheless after moving it in the new apartment (I suppose this was the cause), a geometry issue appeared:

Image

As you can see in the right side of the picture, there is a kind of "wave" that deform the geometry of the image.
I suspect that the problem can not be solved completely via "software" in the service menu, but I'd like:

a. some suggestions to fix the geometry issue
b. some explanation, if possible, of the service menu options (I know it could be long... but maybe it could be useful for other users? Or maybe there is yet online a resource easy to understand?).


Here there are the screens of the service menu:

1. I don't know what to do here :)

2. Service menu:

3. Geometry (it would be GREAT an explanation of all the options here... e.g. what's the difference between v-zoom and v-size? how can I save the settings? it is possible to "reset" the values or how to proceed gradually to obtain a good geometry? Thanks)
Image

4. Service menu?
Image

5. Design?
Image

6. Audio settings?
Image

7. IF Adjust? (what means IF?)
Image

8. Some "stats" :)

So farther to fix the geometry issue (it would be great but.. maybe I'll have to refer to a technician?) , any further information about the features of the service menu, and maybe some suggestions to improve the configuration, it is appreciated.

Thanks again and really sorry for the length of the post! :)

You're not fixing that with any service menu options.

You wont get a technician at a reasonable price these days, just pick up a new one.

Aside from the price, it is a difficult fix? Maybe I can find a technician for free, if it is not so much complex.

It looks to me like the yoke has shifted, which is repairable but awkward to do on large screens. You could actually have a go fixing it yourself.
