[quote=stanman2242;49269569]The SMPS can be bad even though it does not look bad. The 450 volt cap is frequently bad
without looking puffed.
If it is a HL-T6187SX and not a SAX I have the led driver board cheap,
I have many of them. $25.00 + ship.
I also have SMPS for $35 & free ship.
I also have upgraded SMPS for $55.00 which has better parts than a new one from samsung, but I think you would get a year at least out of the other one.
The SAX driver board costs a bit more.
If you have never replaced the SMPS it sounds like a good possibility since you must have a lot of hours to have replaced as much as you have.

Yes, it'll be nine years old in April, so yeah, it probably has a lot of hours on it. Today, it finally won't come up. It reboots a couple of times, and then after three tries, all three front panel LEDs blink ("Optic chassis may be defective. Please contact a certified technician.", according to my service manual). On the first try I had sound, but now, no sound. I've had the engine out a few times to replace the red LED, the DMD chip, and all three fans, so I'm pretty familiar with replacing parts. It is a SAX (SAX/XAA). What's special about a SAX?
On your upgraded sub SMPS board, have all the caps been replaced? Blown caps I'm familiar with - years ago, I had to replace motherboards in several Dell OptiPlex GX270s, which had a known issue with blown Nichicon caps.
Anyway, just let me know what you think - I really like the set, and I'd like to get a couple more years out of it. I actually work for the company that invented DLP (TI), and before I got the set (a free gift for my 25th service anniversary), I talked to the guy that was the lead engineer on the LED DLP engine. Thanks!
