Above are a couple of training manuals so you can understand whats going on, the last link, is for your exact make model, service and user manuals, pay for unfortunately, i couldn't find any free links.
Below is a training manual for JVC. For your chassis TV. http://www.eserviceinfo.com/index.php?what=search2&searchstring=HV-53PRO

You need to check and see if the voltages from the Power Supply, are correct, if they are NOT nothing else can be..You see it may have a fault, that's caused the lamp, and low brightness in the first place, your set obviously has a fault. Now if you feel that it you do not want to do it. It is my professional advice is to get you set looked at by a JVC Authorised Service Centre, and ask for free "Quote", this way, you will be able to make an informed judgment, as to repair or replace. As these days seemingly insignificant SYMPTOMS, often cost as much to repair as it may cost to buy.

Thank you, thankfully today is a busy day.

After reviewing the troubleshooting guide for your set, there are four settings I recommend you review:

PICTURE MODE: Bright
DIGITAL VNR: Min
Super DigiPure: Max
PICTURE MANAGEMENT: On

I trust the LAMP indicator is not blinking at all since bulb replacement?

I hope that helps.

Why is my tv jvc hd70zr7j showing a blank black screen when i connect the hdmi signal cable? the ps3 used to work fine before but since i moved into a new place it just shows the black screen


you have a HDMI port Failure that's not uncommon many people fail to turn the units off before switching cables around it only takes a momentary short on the 5 volt line to one of the other lines and it can short it . or it may just be a normal failure . but you would have to change the .with the AV and HDMI ports on it to restore operation . your set probably has more then one port ? have you tried the others . by process of elimination you have ruled out its the game and cables so it points back to the tv

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.

Dark Picture


Sorry Don

Smoking absolutely destroys these TVs. Just like Teeth, the smoke gets inside and permenantly yellows the Light Prism. Since the Light Prism is responsible for passing light in these units, the yellowing dims and yellows the picture. There is NO fix for this.

Cleaning these is dangerous since all the parts have either a UV or Polarizing coating on them.

Again, I am sorry but this is the truth. On the other hand, try pressing the "Video" Button to see if one of these settings is any improvement

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.
