Got a Panasonic PT-RZ470U Laser hybrid projector here, works fine, except it has 2 issues. First problem: It's a 3500 lumen projector. It currently has less brightness than a 1000 lumen HT PJ. Second issue: the brightness flickers in intensity. Now there's different modes and all that too of course for "cinema, living room" etc...
Switching to the dimmer modes makes the picture turn somewhat magenta of a tint. I feel this is related to the dimness issue as well.
Now there's nothing in the service menu to tweak the brightness. But I believe I saw in the service manual (or somewhere else) that this can be adjusted, a setting called "Drive current" for the laser light engine. This setting can only be altered though, using the Panasonic service software that I obviously cannot get.
So, taking that ability out of the equation, is it possible this can be fixed with servicing the laser/LED ballast or PSU? Obviously something must be weak for it to be flickering and so dim. The laser phosphor wheel looks perfect, and the LEDs and laser diodes do too. The projector has 8600 hours out of an expected 20,000 hour lifespan on the laser engine.
Also, since the brightness flickers evenly in intensity/color, (it gets dimmer as a whole, not just green or red or blue), I don't believe its the laser diodes or LEDs that are the issue, since the color stays the exact same, it just gets a bit dimmer when it flickers, which is all the time.
Any help would be appreciated, I know it's a long shot since the projector is fairly new.
