I wonder if the Bulb wasn't involved in some other fault, that was what was wrong in the first place, i would wonder if there were not some components that made the "Lamp" go faulty, or the "Faulty: lamp, has damaged some other electronic components on the board of the unit.
Please find above your
service manual, this has troubleshooting steps to isolate and hopefully remedy, this problem. Work through the easy steps, and you should be able to isolate and repair. Also the service manual gives you all the part numbers too.
However if you don't wish to DIY, then it is my professional opinion that one should First, get a "Quote" from the manufacturers recommended service center. JVC, in your case, what you do is, please contact a local or head office and ask
them, for a referral to an Authorised Service Center, near by. I cannot stress how important that last point is. It is even worth the cost of shipping. You see an authorised service agent, will have trained staff, trained on their brand, also they have first hand access to parts, original parts. This will actually save you money and ensure you can actually get it back fixed. Of course asking for a "Quote" also gives on the option of repair or replace. Often my clients,do not go through with repair, unless it is moderate, but in some of the more costly jobs they see it, as do I, that a replacement, with a warranty, is often a better option.
