• Reset component settings. Usually, the problems you encounter with a projection TV may be resolved through the resetting to its factory settings. If you experience inaccuracies in the color, reset the television's PerfectTint/PerfectColor capabilities. Simply press the Menu tab and then highlight "Perfect Color" using your right key arrow. After this, press "Enter" and then "Reset" in order to reset to factory settings. If you have audio / video problems (VCR or DVD player), simply press "Menu" and highlight the "Reset" option.

Reset television controls. In case you cannot fix your TV via its component settings, there are other ways of resetting. Just select "Menu", key in "1, 2, 3", and then press "Enter." In doing this, the TV's manufacturer's specifications will all be restored. If your TV's power system does not function, you should perform a complete system reset. You can do this by clicking on Reset System button located at the TV's control panel. Your television will be turned off and then a green light (LED) will quickly flash for approximately one minute. Once the light has stopped flashing, your TV should immediately turn on.

You might want to talk to JVC as this model had all kinds of issues--missing any color, picture inverted or backwards just to mention a few.The solution was to connect it to a computer and use a jig from JVC and download two up grades on sd cards and install them manually.I mention this as the Light engine in the set communicates with the main chassis and you in fact may have a issue with that.At least make a call to JVC---saw about 40 sets with this model where this cures all sorts of communication issues--the engine if "set" wrong could easily cause this problem.

If the DVD works from rear inputs the issue is likely for the tuner in the set, Unplug power from set and any box being used for signal for several minutes and power back to see if a reboot helps.

I would not even attempt that If I was you on this model, what is dirty, spider webs or what?

This set is prone to the audio board inside failing---all the audio is on one board, last one I replaced was just over 100 dollars.

I have seen several of these (some brand new) where the audio board fails, if I remember it wholesales for just under 100 but is not real easy to get at---entire audio circuit is on it.

Problem could be in the Light Engine and it may need to be replaced. which is also known as the optical Engine PN# TSCOP7A-SAA

The set has a receiver inside that the remote transmits a infrared signal to--if remotes known to be good do not work on set the receiver is bad.

This model from memory had issues with wrong colors, missing colors, picture backwards and picture inverted,dead set etc. If it is the model I recall--it had a primitive upgrade done by uploading two programs onto sim cards and with a desktop computer connected to the service plug inside doing the upgrades one at a time---JVC had a jig with adapter for connection to the service plug.Did not take to long and worked in almost all cases--Contact JVC and if I am correct you will need to take it to a JVC service center (any authorized repair shop)They may have by now come up with a better way to do it so do some research.

Replace or have replaced the Audio board in the set----a lot of them fail.

either speakers turned off, or an audio problem which was common on this model----the entire audio circuit is on one board which may still be available.

No its not dangerous, eventually the set will not power up any more and the lamp will need replacement. Having a replacement lamp ready is the best bet it only takes about 3 minutes to replace the lamp. Your model uses the TS-CL110UAA. Whcih is available with the housing from www.tvrepairworld.com they also include installation instructions.

No there is not.

I presume you have no sound via the a/v inputs as well as cable or coax input.


We do factory work for many brands including JVC.

I remember one of these sets only a few months old with no audio, JVC exchanged it as the customer was angry (understandable). Ten minutes later we get a email and a call from JVC telling us set has been exchanged and they do NOT want the old one back---do whatever we want with it.

I had tested the set, following the audio circuit to a single board that supplies all audio--board was not real easy to get at and was on "backorder" meaning lots of them were bad and JVC was out.(which is why the set got exchanged).

I had the board ordered and about ten days later the replacement arrived--installed it (it was sandwiched between two other boards) and set worked perfectly===we ended up with a nearly new set (board wholesaled for about 80 dollars) and sold the set used with an extended warranty.

My point is if no audio from tuner or rear inputs it is a shop repair as most shops will not tackle this problem in this set IN THE HOME..

If you have audio from ANY input it may not be the set.

Let me know if you have questions, I am here to help you.
