Hello: Welcome to NLG. Glad to have you here, we can certainly help you with this.
I work on Ceronix 1492 boards almost every day so I am very familiar with them.
The first question I have is what is your level of knowledge working with monitors, safety wise, etc?
I recently started a series of videos on Youtube doing an overview of the 1492 (which includes 1490) and the layout of the board. The first overview video is live and the first of two repairing an actual board. I also posted one recently for another member who wanted to see how to pull and swap the board. I am not a professional. LOL
I have a basic "checkup" I do on every board before I power it up, if you can tell me how it died I might be able to narrow a few things down for you.
1. Depending on date of manufacture, caps are highly suspect. However, only two on the board are likely to cause complete shut down. Having said that, some of the earlier boards have original caps that seem to last forever.
2. Are you getting any chirping from the board? You might have to listen very closely, sometimes it sounds like little puffs of air...sometimes fast sometimes slow and steady. This tells us a story.
3. If completely dead, it could be flyback. In which case you might as well buy a working board. Flybacks are not available, or rarely.
There are a few members and supporting shops you can send your board to and we can look at it. Feel free to send me a PM, I am happy to look at a board and cap it for you if the flyback isn't dead.
