1) In customer menu, adjust all video controls to center,then
increase "picture" to 3/4
2)Locate focus/screen adjust block above chassis...adjust
RGB screen controls for best mixture = B/W tracking..
Check with customer color level at minimum..should look gray.
If you turn screen controls up too much,you will see faint
re-trace lines in picture.....once B/W looks good,put color level
back to middle...................................................T.

Your model doesnt have a bulb since its a rear projection TV . It has three picture tubes, However loss of video with audio still working is usually caused by a vertical output failure.

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.

Picture is gradually getting darker


It sounds to me like your bulb is going out. You have a rear projection TV, and since so, there is a bulb that shines the image onto your screen. Because of this, you need to replace the bulbs after awhile. Call customer support or look around online for a replacement bulb and directions on how to change it. Very simple, but takes a little time and effort. :D

Philips Projection TV Bulbs need changing


Buy a new television. The "bulbs" are actually small picture tubes, also referred to as CRT's or guns. There are three of them, Red, Green and Blue. The cost for the tubes alone will probably exceed the original purchase price of the television. If the new tubes do not have the lens assembly attached, then you will need to transfer the old ones. This involves draining, cleaning, and refilling the coolant chambers. Once installed in the set, there is a series of mechanical and electrical adjustments required, to get the picture aligned or converged. This procedure is not recommended for the inexperienced. If cost and time are not an issue, then everything can probably be found on the Internet. Simply search the web for your model number. You will need the remainder of the model number first. There are at least eight models starting with 46PP9302. You are missing three additional characters.
