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

JVC HD 56g886

I bought this unit 2 years ago used. Recently it went into protect mode. I pulled the bulb and found it to be broken. Yesterday I replaced the bulb and the TV started working. It however only lasted an hour and went back to protect. I pulled the bulb to find it broken again. Did I get a bad bulb or may there be another problem causing the bulb to break. Thank you, Dr. Chad

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.

Testimonial: "Can I use some light air pressure to blow the bulb and fan compartment out. There is definitely a fair amount of dust in the compartment? When I plug the TV in, should the fan come on immediately?"

    Most will come on immediatley but some may be thermostatically controlled. Gently turn by hand to see that it spins freely.

if you purcased a LTI lamp then the possibilty of a bad lamp may be the case. LTI lamps are cheap and are poorly manufactured. if it is a JVC lamp then you may have further problems such as lamp balast, or thermal sensor. clean the fans and filtersfor better air flow. keeping the lanp cool is important for the life of the lamp.

SOURCE: Gray spots on screen on a JVC HDILA model HD 56G 787

The HD-ila sets accumulate a lot of dust in the light engine. The worst offender is the little fold mirror just under the lens. I take my set apart about every 8 months or so to clean all the dust from the light tunnel and all lenses, mirrors, diffusers etc. The picture really regains it's pop when this is done. Unless you are a skilled technician though, I would recommend against attemptimg this procedure as you need to disconnect the individual color lcds. Check with a local service center to get it properly cleaned.

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!

The gray spots are caused by dust on your lens, very easy to clean.

Power down the TV.

If you open the right side access panel (right side as you are looking at the front of the TV) you can see it in the middle, it's not very big. Using a scratch/lint free cloth, gently wipe off the lens or use a vacuum to **** up the dust being careful not to actually touch the lens.

Replace the access panel and enjoy your spot free screen.

JVC HD-56G886 tuner stopped working


My (unfortunate) guess would be the Tuner received a static discharge when you were changing the antennas... this time of the year is bad for static - if you're in a "Winter" climate.

Receivers have a very sensitive FET or MMIC amplifier right inside from the antenna connection to make it better for picking up distant stations.

However, this same "sensitive" amplifier is also prone to being destroyed by even a small static discharge... especially if the tuner had its power turned ON.

Sad to say, it's likely toasted... :-(
(I hope I'm wrong... but you have already tried all other possible solutions)

You online and did you receive my email concerning no sound on JVC HD 56G886, Part Number: QAS0251-001 . Ed robinson at majorchordstm@sbcglobal.net?


The fault can be confirmed only after a proper audio test is done. The unit must be opened first so that the speakers can be checked for continuity. If this is okay then feed a audio into the audio in and select the video for the auxiliary input. If there is output then the output is good and working and the fault can be with the SIF- sound intermediate frequency section. You will need to inject audio frequency so as confirm the failed section.

61 inch projection tv flashing on and off


The most common problem with JVC LCD rear projection TV is bulb failure. Do not panic, this is normal after 2-5 years of use.

You can change the complete assembly or for less cost just change the bulb. Do not use Osram or other funny brand "rebuilt" or locally made bulb. Use a Philips replacement and all should be good.

Changing the bulb involves removing the lamp assembly and taking it apart like a puzzle and replacing the bulb. JVC are a little more difficult to do than most others because the wires on the original bulb are molded into the glass on the original bulb. Wires must be cut and stripped of insulation before connecting to the new bulb.

All JVC LCD Rear projections TVs use TSCL110 TSCL110U TS-CL110U Lamps.

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.

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.

Dark Screen


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.

Hdmi Issue


Most new HDMI DVD players use High-bandwidth Digital Content Protection (HDCP)on the HDMI output.If you try to play this on an older TV that is not compliant with these new standards it will not work.This standard came out late in 2004 that is why your older player still works. There is also a service bulletin from JVC about upgrading the software on your TV for HDMI compatiblity issues.If you want a pdf file of the bulletin I can send it to you.
