All fillament based lights will dim as they age. Some of the newer/better types it will be unnoticible.  If you are losing image quality or brightness you may have a bulb that is nearing the end of it's life cycle.  A glance at you owners manual or the manufactor's website should give you an indication of the expected life of your bulb.  Also most of the projector made in the past few years have a counter that tallies the amount of hours your bulb has been on.  A more likely culprit is probably dust accumilation somewhere inside your projector. Most projectors have filters these days and need to cleaned at certain intervals and in certains ways.  Not cleaning these filters can cause heat build up that can increase operating temps and shorten the life of your bulb and or projector.  Or sometimes jsut fail and cause a dramatic decrease in image quality.  Again these things are vendor/model specific so you will want to check with them about your particular model. Hope this helps.

Brightness problems with sony kf-50we610

This is typical for a set that uses a lamp, as the lamp needs to warm up.

If it is taking longer than normal to brighten up, then your lamp could just be aging and needs replaced.

Turn set on picture is dark.. if I leave the TV on.. in several hours it's viewable.

I have seen several Samsung's including 3 that were only a few months old at the time where it was the lamp---one was so dim it was very hard to even see the picture or that the screen was lit.

Two suggestions here: One of course would be to buy and gamble and replace the lamp.

What I found in two of the three cases was when I removed the lamp the glass pillar inside it was "bent" at a angle from heat or a natural defect--in both those cases a new lamp cured this dim picture issue.

Set will monitor the lamp and if too dim may shut set off or even blink for a prolonged period of time.

If the lamp is over 2 years or age (average life) or was replaced with a non-Samsung lamp you are going to have to take the gamble to try another one.

Inspect the lamp---that pillar supports the filament and if bent the lamp is suspect at best.

I turned on my projecter and the screen was not bright enought

There is reduction in brightness due to aging of the lamp. Normal life of projection lamp is 2000 to 5000 hours depending on the mode of operation. In power saving mode it is more. Please see the manual for specifications. If you have switched from standard mode to power saving (economy) mode, the brightness will reduce. If it is not then check the number of lamp hours & replace the lamp accordingly.

The display projected is very faint. The lamp light is not blinking to indicate a problem. Is this an issue with the settings?

Check the bulb hours remaining through the menu. The bulb gets dimmer with age, so it could be close to life expectancy (2000 hrs regular, 3000 hrs Eco) and failing. The indicator light is based on hours only and will shut down the projector after (2100 or 3100 hours of bulb use), so it could still be the lamp failing or a power supply issue, especially if it's dim right from start up. Hope this helps.

The lamp will dim as it ages and will do so quicker as it approaches end of life.  Do you know how many hours the lamp has been used.  How old is the TV?

Screen getting dark

If you have never changed the lamp this is more than likely the issue, as the tv ages the lamp looses brightness. Most lamps are rated for 3000-5000 hrs of use. Replace the lamp assembly part # UX21514 and you will notice a much brighter picture. You do not mention if the tv plays the right colors on the entire screen. These have had light engine issues.
Good luck with it

Problems with brightness on the hitachi 50v810

Yes, they dim as they age, and you've done well to get 3 years out of one.
Projection TV makers charge an arm and a leg for their replacement lamps. They make it easy to do but as a result the custom lamp assy is expensive. The trick is to just buy the bulb for your model TV from any number of us aftermarket sources at a fraction of the lamp price and install it in the old lamp yourself. really easy.
