I am buying a new TV and want to give my daughter my old one,it's a 50" Grand Wega LCD rear projection, and I am curious if I should change the bulb before I hand it over to her. I have had this TV for about 4 years and havent changed the bulb, will a new bulb brighten the picture? Do these bulbs dim with age? I havent noticed any dimming, it still looks great to me but I see it everyday.

Thanks. Aaron

Figure about 6-8000 hrs lifespan on the bulb. Obviously the closer you get to that may hours, the more likely you'll need to replace the bulb. If you are at say the 6000 hr. mark, then why not replace the old one and save it for a backup just in case?

Im just curious if they actualy do dim? I was told when I bought the tv the bulb would last about 5000 hours, but so far its ran more than 23,000 hours easy. The TV stays on all day, every day, even when we leave. I was told the tv would last longer if left on, so far that holds true. I guess it works like any other bulb, the more it goes on and off the faster it blows. But do bulbs actualy get dim over time? Thanks again! Aaron

I'm sure ot behaves like any other lamp. It's always darker before it totally goes black.

By the way, I wish you'd stop posting pics of your cabinets. It's getting depressing! I'm thinking of getting an HVLP conversion sprayer but I'm having trouble finding a compressor small enough to carry, but capable of putting out around 8 CFM @ 40 PSI. Any recommendations?

Hi Brian,

If you're going to be shooting cabinets, here's what you're looking for: <A HREF="http://www.spraygunworld.com/products/Astro/Astro">http://www.spraygunworld.com/products/Astro/Astro</A>%20Pneumatic%20-%20EVO4014.htm

It's a LVLP automotive gun. The 1.4 tip is perfect for both solvent and water based lacquer, polys etc.

A lot of shops will use this for their primer guns and paint with $600 Iwata's etc. but this gun is perfect for a hobbiest and for cabinets. It'll spray much smoother than any of turbine guns unless you want to spend big, big money. Even then, this gun will lay down a really smooth finish with a little practice.

I dont know where you would find a compressor like that, you might look into one of those turbine/HVLP setups, I have never seen one in action so I cant tell you if they work well or not. My Gun uses 12 to 14cfm at 30 lbs- 10 lbs at the tip, so I use a fairly large compressor. Do you need it to be portable?

Space is the big concern. All my shop tools have mobile bases to accommodate the small shop area.

That gun looks very reasonable. My biggest problem has been finding a compressor small enough physically with sufficient output to run the HVLP units.

I replaced my bulb a couple of months ago on my 50" LCD rear projection. It made a huge difference. I am not sure how many hours I had on it, but it had been 2 years. I was able to find a new bulb on Ebay for $160 shipped.
What tipped me that it needed replacing was when I bought a new bedroom set that was an LCD flat panel. The difference was quit shocking. After the bulb change the flat panel is still better, but not by all that much.

You could get a vertical compressor, this is the one I use and it works great and was a decent price for the amount of air it puts out. I use a Sharpe Finex HVLP gun and it sprays very nice and cost around $100. Aaron

I have a 62" DLP 1080P res. TV and I swear the bulb gets dimmer about one or two months before it burns out. The last time it burned out I had the repair man take the TV apart and clean it .Boy did it get dusty in there. That made a huge difference in picture brightness, it looks like the day I got it. I am disabled and between me and the kids the TV is on about 16hrs a day or more and I have had to replace the bulb once a year. I don't know what the bulb costs because I have a five year warenty on it and the bulb is included. A good cleaning might be a good idea after a couple of years though. I imagin an LCD would probably get dirty inside too.
