SX-636 dim display

[Descartridge]

I have a Pioneer SX-636 with a display problem. The blue illumination through the black dial plate is very dim.
The lamps have been completely replaced.
Has anyone experienced this and is there a fix?
Thanks

Did you make sure the bulb is 8v not 12v?

positively 8v, thanks

could be you got 250ma instead of 300ma fuse lamps

Who'd you get the bulbs thru???

IIRC, WJOE had a problem with some bulbs in that they were 12V, but marked 8V. The problem has been corrected I believe.

I think I've seen a few examples posted here showing the older black-faced units fitted with LEDs showing off very bright, sharp features and dial definition. Just a thought.

Here's one

Thanks Watt, I will give this a try.
I did replace all of the lamps with 8v 300ma lamps from the recommended supplier and the display is still unpleasantly dim.

How dim is it, I just picked up a 636 and its not a super bright display. Though it is easily read. Personally I'm not a big fan of super bright LEDs for these receivers.

I've had my original SX-434 since new. 5 Fuse Bulbs (paralleled). Looks the same as what Water's picture is showing. It's NOT supposed to be overly bright, like a MArantz is at times. It's more of a "heavy glow" in that it's trying to get the blue thru the black of the dial face. You put too much wattage back there and you'll wash out the black.
