Do they actually have the worst *bulbs* (they use Philips which are very good) or is actually their power supply circuitry and ballasts that are the weak link?

Thanks! I'll see if I can locate the post.

I have a 550es/675, same as you had!

So just Ali Express or eBay?

So the ballast resistor is in the projector somewhere, not the lamp housing or bulb? You'd think replacing that would be easy.

Yup. In my experience it is fairly hit and miss if you get a good one or not.

As an aside, Sony told me to use a new bulb for the first 100 hours out of the box in high mode and it would mitigate the flickering thereafter.

I never got a chance to test that out. Shame they didn't put that advice in the manual...…..

I've never swapped a bulb or full lamp housing., Getting a bulb for say 150 and getting 1000 hours is probably fine for me. The full Sony lamp replacement less palatable...

Anyone know if it is hard to do just a bulb? Risk of damage to housing?

PS - the shorter lamp life on high has never been a consideration with me. I like the light level an more importantly the noise level on low...
Just make sure you get the right bulb. There are 4 brands that make compatible bulbs and only 1 actually lasts and works well. I had it documented but must have cleaned it off when I sold my sony.

Yea honestly it's probably that. And also they drive the bulbs lower than JVC drives them on low, so it might cause the flicker more.

Did this on a Benq and still got flickering to the point that after a 400 hour stay on Normal the flickering is still there. Maybe it would have been worse if I didn't .

Could it have been Lutema? Does that ring a bell? I've been searching online and this sounds good.

No, as @Archibald1 said above, it's Phillips.

Cheers
