Samsung HLR4667
I found this TV at the dump and fixed it up last year, it has a bulb from a samsung tv made a year before it. The bulb is 10 years old and is still working but my picture gets dimmer every month and is now only viewable in almost darkness. I could get a cheap $30 bulb that has 2,000 hours on it or $60 for a 8,000 hour bulb but thats a lot for nothing. LEDs basically last for ever so is it possible to use a LED in this DLP if so what kind and how much.

I have salvaged and fixed 18 TVs (1 DLP), 22 LCD monitors, 8 stereos, network stuff, and more laptops and computers than i can count.

Re: Samsung HLR4667
Short answer - no.
Longer answer - the DLP bulbs are started with 10kV+ pulse and operate on high voltage DC around 200 to 400V DC. Designing in an LED jury-rig would be extremely difficult especially given the initial high voltage pulse. You would expend significant engineering resources doing this, with which you could buy an actual LED DLP (the A750 from Samsung comes in 61" and 67" and is fully LED lit.)Please do not PM me with questions!
