JVC HD 56GC87 PICTURE NOT SHARP


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
