Question about JVC HD-56G886 56" Rear Projection HDTV

1 Answer

Dark Screen I have a JVC HD-56G886 purchased in sept. 05 and my screen has been getting darker and darker. We have had to replace the bulb once in Nov. 06. I have the settings for picture and brightness turned up all the way and the screen is still very dark. Is there something that just needs to be cleaned or is there a bigger problem? any help would be great!!

The lamps in these normally last about 3000 hours (if your really lucky). The bulb will start to loose it brightness as a matter of due course at about the halfway mark. It maybe that you are running the unit in the non economy mode that they are fading faster then normal.
The sets have a reputation for not being good with lamps though.

Have a look at the lamp though, make sure it has been off for at least an hour to let it properly cool and check for dust that has settled on it. Also if you wipe the lamp, make sure it is with a dry cloth, or allow plenty of time for any moisture to completly dry before turning it on if you use a damp cloth.

It could be dust and or lint in the tv. The bulb has a fan to cool it and if it is plugged with lint can cause the bulb to overheat and fail. Lint or dust that gets on the bulb can also cause premature failure. Remove bulb and lean fan and intake screen thoroughly and check to make sure fan is operating. Then install new bulb. Hope this helps.

Have black dust looking spots on my screen.


Howdy;
Yes there is a way. The easiest for you would be to remove the back top of the TV. That will give acess to opt lense and mirror. But first check the Lamp and inspect the lense that the Lamp into. It does not take a lot to cause your concern. Use super soft cloth and wipe surfaces.

Good Luck,Big Irish.

My JVC 56G787 is dark and bright is turned all the way up


You need a professional.
Stop using the TV until it is repaired.
Continue to use it and your problems will multiply and grow more expensive.
Call the manufacturer to find you nearest authorized service center.

JVC HD DILA 56G886. replaced lamp and now it shuts down after 10


we found that it is an auto shut off system on the TV due to over heating. The lamp, if not cooled correctly shuts down. We added a mini fan in the back and it seems to work fine now.

I fixed it!!!! If you can open one of the sides (on the JVC there is a little door with a screw), then you can clean the projector lense in the middle on the bottom. It kind of looks like a big light bulb. It seems there is just dust on the glass that is projected onto the screen. We had a big gray spot and cleaned it with a damp glass cloth and Ouila! It disappeared. I scored MAJOR brownie points with my husband for this one! He wanted to replace the TV!

Call your cable company, the lamp has nothing to do with the inputs, Maybe one of the connections is barely connected from moving the TV to replace the lamp.
