I also bought a "genuine philips" bulb from this reseller.
When it was time for replacement about 1year after buying it i contacted the seller and asked:
1. how to connect it as it does not have the small glass tube like the original osram has. See attached images which glass tube with an electrode inside i mean.
It seems like some kind of pre ignitor which might be helpful for something,maybe to resolve the blown ballast board issues they had on the x3? Anyone knows, chime in and tell me 🙂
2. I also wondered if it matters which cable goes to which post (aka is there any positive or negative)
3. If they can guarantee that the lamp will work and wont destroy my projector?
After several eBay messages back and forth i got answers.
1. Glass tube not needed.
2. Does not matter since its a AC lamp (thought this sounded strange as there is still an anode and cathode on mercury lamps)
3. No, they could not guarantee. No reason why, basically just saying out of warranty time. Ok, i kind of get that one, but would be nice to hear that the bulb was still a proper fit for my PJ which they also could not say any more even after they found my order based on order nr.
Anyway, i connect the sellers "original Philips" lamp as the osram original having the lead going to the rear of the bulb on the same cable on the new one, guessing the cathode / anode placement was always "lamp rear entry" /"reflector skirt" screw terminals.
Started up and it was PLENTY BRIGHT (my old original had 6000h on it...crazy dim, so that might be the reason why i felt that way).
Ran it about 50hours or so and then one day wanted more brightness due to sun leaking in so turned to HIGH lamp mode.
After about 30minutes it smelled like burning plastic/electronics. I searched everywhere for the smell (AV pre amp, Amp, HTPC) and as last step took out a ladder and climbed up to JVC DLA-X35 and smelled at the exhaust vent. OUCH that was it defenitely as a strong smell of plastic burning came out of the front vents. Imediatelly turned of PJ and allowed it to cool down as normal
Made a full tear down and found the reason, you can see this thread on AV forums (my post is the latter one on page 2 with a detailed description with images under Boogieman).
So as of now I dont know if the issue arose due to fairly clogged fans, the lamp or a combination (the retractable bottom filter was 100% clean so not that for sure). I just know that JVC filter system is A JOKE. Zero rear intake filter (unless you count the coarse metal net in the chassis lol) for lamp and power/PCB section and a "mosquito catcher" filter for the optics (the bottom side extractable one). How did they think?
I just know that I will probably buy a OEM now even with many hours left on this lamp. Until then i run it in low lamp mode and high altitude setting to make sure pj optics are properly cooled.
Also i will try to find a high flow filter with better filtration as i DO NOT want to redo this teardown and current JVC 4k alternatives are too expensive based on difference in quality in image. I was recently on a showdown of the N6 and i cant say its worth more than 2* the price of the x35. It seems like they changed filters to some coars foam filter though so that might be a important improvement 🙂
