Question about Audio Players & Recorders

Display is faded and remote not working properly

Our projection for an optoma ep749 is faded. We still have 325 hours left on our lamp. Please advise what this problem might be. Also on the same day the remote will not scroll over to image 1 or image 11 tabs on the menu display for some reason. Never had this problem before. Please advise.

    we have tried the dust and such. Doesn't seem to change anything. So depsite what the hours say... the lamp could just be going out. I thought lamps normally just quit working as opposed to fading images... Please advise.

Despite the "hours left" on your projector, the lamp could be nearing the end of its life. Recommendations:
1. Make sure the vents and filters (if applicable) are clear of dust and debris.
2. Make sure the projector is well ventilated. (i.e. no obstructions around the vents)
3. Replace the lamp. They're around $200 on eBay. After replacing, reset the lamp timer (see your manual).
4. After replacing, run the projector in eco-mode if the brightness is acceptable. This will extend the life of your lamp.
5. Always let the projector cool down before unplugging the power or turning the master power switch off.

I don't know what would cause the inability to access all the menu options.

Hope this helps somewhat.

    Unfortunately, all projector lamps fade over time. I have a Sanyo Z3 that required a lamp replacement at only 800 hours due to a dim image.

    Here's some great background info on projector lamps.

Be sure the power cord is plugged into a properly grounded wall outlet. Then, press the POWER button on the projection display or the remote control to turn the unit on.


While pressing the VOL- button on the projection display, hold down the PIP or SPLIT button on the remote control at same time for more than 5 seconds.


When reset procedure is complete, the screen will indicate that the lamp has been reset!


NOTE: When lamp time reset is finished, the LAMP indicator goes out!

    The procedure may vary from Sony model to model. These procedures are for Sony Rear Projections only. For other models, please consult your manufacter's website. All rear projections have the option of reseting the lamp hours. This helps since you will know how many hours your last lamp ran for. Normal lamps should run between 5000 to 8000 hours.

    Try the following procedure:
    Please be cautious when entering service mode. Following the information below and you will have no problems.

    Enter service mode by pressing Display, 5, vol +, Power On.

    Proceed to the Option-E screen by pressing the 2 or 5 button
    Option-E 0 0

  • 4

    Change data to 1 using the 3 button on the remote

    I have a sony Vega 55" kdf-e55a20, It is 3 years old, and now the picture and sound fade away for 10-15 sec every hour or so and comes back! Anyone knows what the problem is?


    Hi,
    Lamp is getting weak and TV shuts off and turns on itself because of weak lamp in TV that you see picture and sound fades away for some time until TV reboots.
    Replace lamp in TV to solve this issue. Lamp replacement procedure is written in user manual and its an easy work.
    Please buy Sony original lamp for your Tv safety.
    Thanks.
