You cleaned the reflector glass, then tried to make the manual adjustment of the color to have good convergence. you can do the adjustment in the menu set up. if can not get with adjustment, their might be a problem in the convergence circuit board.a bad convergence ic or resistor.

Do you have your TV plugged directly into the wall? You cannot plug into a power strip, it needs its own direct power source. Also, I have heard that there can be electrical problems inside. I have this same model, I love it, picture and sound. I just replaced the bulb for the first time last night. It was a little premature to replace it now but I know what caused it. I bought a new bulb and it works like a gem. If you ever need to change the bulb do it yourself. It takes maybe 2 minutes. The bulb looks like the Flux Copassitor and all you do is remove the door in the back on the side. Unscrew the the 2 screws that hold the bulb in and just pull out. When you put the new one in make sure you do NOT touch the glass on the new lamp. Just slid it in and screw the 2 screws back in and make sure the door is closed and tight. My uncle had a service guy do his and he got raked for 5-$600, The bulb costs about $200. Should last about 5-6 years at a rate of 5-6 hours of TV on time. Hope this helped. If not, sorry, but at least you know how to change the bulb. Good Luck!!!

Hi, don`t know if you`ll be able to find this but D9405 a surface mount diode on the main power supply board is a known issue for yours and many other models, it has to be re-soldered not replaced, other joints in area may also need to be "touched up", other than that I had one where connector CN310 was not seated correctly, one side of plug was cocked way up, other than those 2 you may have a bad ballast (board that the lamp is connected to), Be sure that the lamp door is securely closed as they have a switch built into them and if the switch is not closed the set WILL NOT start, hope this helps you out, BMW Rider

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.

Look in the owners manual for the directions on how to remove the lamp. Your model the lamp goes in from the front on the left looking at the TV. There is a thumb screw in the back on the corner holding the left front speaker on. Under the panel there is another thumb screw holding the lamp door on. You will need a Phillips screw driver to remove the lamp. You will most likely find that the lamp is bad. You will either have to order a lamp directly from JVC, a service center or a parts distributor.
