JVC HD 56GC87 PICTURE NOT SHARP

Hi, I am the one who posted about the non-crisp picture...Not sure why the model didn't show up on the post...The TV is 2 1/2 years old....The picure is consistent but very dull, no sharpness, hardly any differencw on HD...I called one trouble shooting site that sells lamps and they said it didn't sound like a lamp problem, and that I should try cleaning the bulbs etc...What do you think? Thanks Chris

On a tv whether it be projection type, plasma or lcd screen, new or old, 2 1/2 years is sufficient time for dust and lint to accumulate inside the tv and its components. Those lamps are a good place to start. There are external factors like humidity, temperature, and the cooling of that tv that can affect the picture over time. To clean those bulbs/lamps you need to be careful and use a lint free cloth like they sell at Home Depot or Lowes. I call them detail rags because they attract lint and moisture and leaves the surface dry. Also a can of clean compressed air like they sell at Radio Shack or most electronic supply stores can be used to clean the dust and lint accumulation on the components. The cooling fans on those tvs and any for that matter are notorious for bringing into the tv anything that is floating in the air. So I would first blow clean compressed air on all the components you may see dust and lint accumulation even the bulbs before I use the detail rags to take any remaining residue from the lamps. The inside of the screen should be cleaned as well. Be sure for safety to disconnect the power to the tv and to touch the frame of the tv to discharge any static electricity you may be carrying due to carpet floors or other objects so that you do no inadvertently damage a sensitive component. On HD tvs all the components other than those bulbs are static sensitive. Just be aware of that. Should this type of cleaning not improve the quality of the picture then I would have to assume that the voltage from the power supply supplying the voltage to the lamps is getting lower with age. On that I can probably help you depending on what you are comfortable doing with your tv in adjustments if there are any. Let me know and I'll be glad to lead you through it if necessary. Good luck and God bless you. Robert

Hi Suzette my name is Roety,
I can help you with your issue ,
First of all make sure you have an HD signal connected.
These days using a non HD box will produce a bad picture on an HD TV.
If using a cable/Dish box set the output resolution to 1081i only,
for picture controls set them all center and max out the picture/contrast control

Poor picture quality


First of all do you have a HD signal?
these sets are made for HD and most look good when you set the HD box to 1080i , the cheaper sets do not look good with a non HD signal.
check all inputs, dvd, HD air, and component and post which are bad to get more help

Dull/blurry picture


Sorry but You Don't.

Imagine taking a small Jpeg photo and blowing it up to Billboard size. It will be pixelized and dull.

Same with HDTV's. You can upconvert and adjust til your eyes turn blue, but you cannot take a Standard Def signal and make it look better by showing it on an HDTV. Some Standard Def material is better than others but ultimately what you see is what you get

Sharpness of the image


Hi,
Putting sharpness up to high will cause the opposite effect. To get the correct level of detail you are looking for you need to adjust all your settings, especially your contrast and brightness levels. A good guide would be cnet.com. They have several posts for TV settings for HDTV. Goof luck. Please post back to let me know how things go.
