SOURCE: 2 new bulbs, still dim picture

It could be a dirty projection lense or the light engine is malfunctioning by a slipped lense in front of the color wheel or the light engine is dirty it self. They are not two hard to take out if the mounts have set marks on them then it is easy to put the engine the way it was.

SOURCE: Sony wega 70 in new bulb lasted 8 hours now

hello.+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672.

This is a new problem.

Power packs deliver 12Volts across the wire to lights.
If the voltage is less than 12V, then lights will not go ON.
It's hard to imagine that 120Volt circuit is causing this problem.

You're not suppose to put power pack on extension cord, but you can do that for short term. For example run extension cord from indoor plug on completely different circuit breaker, and see if symptoms persist. You might need new GFCI that is connected to outdoor outlet.

Buy cheap circuit analyzer at home center and plug into power pack outlet at different times and see if there is a difference.

Buy cheap multimeter from home center. Install battery. Set dial to 120Vac. Put tester leads into receptacle slots when lights are working and when lights are dimming, and see if there is a voltage drop.

Plug a table lamp into same receptacle and see if there is voltage drop.

If you have photo-eye connected to power pack, remove photo-eye and see if that is causing problem.

The other possibility is a ground fault somewhere along the wire that is somehow draining away voltage, causing a voltage drop. For example if you have 20 each 20 watt bulbs for 400 total wattage, and power pack is rated for 300 watts, you would expect dimmer lights -or- non functioning lights.

Next step would be to replace bulbs one at a time.

Next step would be to dig up the wire, inspect wire for cuts, and reconnect each bulb. Check end of wire and see if it is under water. Digging up the wire is very difficult, and we usually just run another wire.

When working on lights, unplug power pack to remove chance that power pack will burn out.
Power pack transformer can burn out if the voltage is not used, and transformer gets overheated.

Please add a comment and say what you discover.
I would like to add your experience to following link on Power Packs.

did you use a genuine sony replacement bulb or aftermarket? Often the aftermarket lamps are not up to par with the OEM versions.

Why has the picture on my samsung 62 inch dlp been getting increasingly darker

Projection bulbs provide a high-intensity light. Most have an approximate 2000 hour life. This can vary greatly depending upon factors such as how often you turn it on and off and how often and how well you clean the filters. As the bulb begins to reach its life expectancy, it will start to get dimmer. A 2000 hour hour bulb, if it reaches that time frame, is expected to be putting out 50% (half) of the brightness that it did when new. It may simply be time for a new projection bulb.

Hitachi 50V710 The picture is dim, then the bulb went out. I replaced the bulb. all works but the picture is still dim. You can barely see the screen durring the day. And can only use it in a dark room...

I've seen this in two scenarios.

First: The housing of the bulb is dirty (the lens the bulb lights onto) and the internal screen is dirty also.

The second: The bulb is wired reversely of the proper way to wire it. This will light the bulb, but will not light as bright as when it is wired correctly!

Thank you and please rate!

Replaced lamp in 55vg825 approx 1500hrs ago & lately the picture has lost brightness compared to when the new bulb was installed. Is there another adjustment or is the bulb defective already? Past...


You are correct about lamps working or not, but that is the extremes. Over the course of operation all lamps lose brightness as the hours add up. All lamps will lose their brightness over time.

Typically lamps only last at best 6000 to 8000 hours. That is not long if the unit is used most of the day everyday. In addition the cheaper the quality of the lamp, cost and manufacture, the quicker they go down hill.

Assuming that you have a low quality lamp what you are experiencing is normal. You may be able to improve the brightness and clarity of the picture by cleaning the lenses, mirrors and screen. I have a tip at

This tip is labeled projection tv but is also appropriate for cleaning an LCD or DLP unit.

Thanks for using FixYa and for the great rating.
