Ok nice to hear, if it is the lamp then I am glad since pj 2 year warranty is through.
I'm not glad that jvc only exchanged 1/3 of their own faulty lamps since they all showed the same issue after 6-800h.
2/3 of those lamps were v3 so they also have issues (the last 2 that they would not exchange)
They actually gave me the same advice as you (which I found out on myself by trial on error before they told me) to go high lamp and then back. That kept the lamps going on a bit longer, but I did not want high lamp & not needing to switch back and forward.
Jvc should either have checked pj during warranty or exchanged the lamps till i got a good one, especially when considering
A. Their OEM lamps are crazy expensive
B. The jvc lamp issue is widely spread on forums
Basically they should apply a good amount of goodwill since their products are faulty AND expensive. If not for the customers sake, for their own (to keep customers coming back)
I will try a bare Philips bulb (have just gotten osram in my expensive JVC oem modules bought directly from reseller here in SWEDEN) from eBay now.
It's said to be genuine Philips and price on bare bulb 60$ is low, but still as high as some manufacturers that sell (according to description) compete OEM lamp modules including OEM bulb.
Also it had clear images on markings indicating its real deal but I will see when I measure it =)
No more jvc lamp based for me at least, next pj week be laser for sure (probably Epson....or Sony if they do one for a reasonable price).
Sick of those lamp costs and burn a lot of bulb time (only use pj, no tv mounted yet but have a pioneer krp-500M brand new in box that will go up in bedroom =) )
