Got a really nice used widescreen monitor for $15 today, begging the question...

How can I service one with a known working screen and either a bad backlight or power inverter for it?

I need all of them I can get and I'm even lucky that mom had not disposed of a 5" Sony Trinitron portable with the only real problem being that the audio and video are offset, i.e. adjust the fine tuning one way or the other and only audio or video works well, but it's a gorgeous picture with an S-video out on the card and an RF modulator with S-video inputs.

Almost bigger than those old luggage all in one Kaypros, Osbournes and Compaqs.

I see stuff from search but I should be able to diagnose this with my meters and go from there.

I should have found one of Navo's girls in a reclining position, VGA into widescreen makes EVERYTHING LOOOOONGER.

Hanns-G HW193D, Vista era, a steal compared to the original price. It used to be cassette decks, now it's monitors, years ago it was Model A's.

I don't know if this will help you, but shopjimmy.com had the parts for a Vizio TV that my nephew had:

It might, but I have to establish where the problem lies in the first place. The tiny monitors were among the first because of the cost of the technology then vs. CRT monitors.

Before it gets confusing, the WORKING one I just got is a Hanns-G but the UNLIT one is HP Pavilion vf15 and yes, I SEE the one on US eBay for twenty bucks (and the idiotic notion of eBay that I'd want the damned thing tomorrow for $60 shipping) http://www.ebay.com/itm/HP-Pavilion-vf15-15-LCD-Monitor-/331602073690

Computer monitors are a dime a dozen here but the truth is usually that many people don't realize how old the earliest ones are and they also may still have the CRT in mind and think the LCD SCREEN has failed or that it can't be fixed and returned to usage for many more years.

My first CRT monitors were 13"...I'm willing to use a FIVE INCH CRT Trinitron to operate one of these computers and in other things at my bench, so a 15" isn't bad and when my friend had a 19" CRT Hanns-G in his photography studio it was an awesome behemoth. Now you can use an entire wall with a projector but 20 years ago the two worlds didn't begin to mesh for me.

There are two potential problems...either the voltage supply to the backlighting is bad or the lighting itself. I'm thinking more along the route of the PS to the lighting as all are out and I'm not planning to open the screen itself unless I rule out other things for sure.

I saw some listings on eBay and one suggests that an HP Compaq model's PS board was also a Hanns-G part or used in one as well, but that's coincidence at this point.

The PSU is chock full o' wicked cool looking coils and after seeing a similar one on eBay I knew the left side board was the PS as I had suspected.

Been to the usual manuals brothels in search and two I can actually trust and no luck yet so I search.

AHA! I used a different query and now HP says the model has SOME relation to f1523, which I've seen a page on elsewhere and can find in History again.

Both vf15 and f1523 are P9619C.

That is a start.

Meanwhile I scored another HP 2009m widescreen, this one without any scratches.
