Did you bump the lens? Is it blurry on all inputs?

Both times bulbs was replaced it lasted 1 1/2 or 2 years right?Use tv on like 4 or 5 hours a day?That the avervage life span of a projection bulb.Try to buy an original JVC pojection bulb last little longer.

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.

yes u need lamp

The bulb part number is: TS-CL110UAA. Take out the bulb and look inside from the front side. Visually inspect any physical damage inside. If it looks clean, lamp might be good

Most likely a bad Polarizer within the light engine of which you cannot buy. The entire light engine would have to be re-built or replaced and they usually start around $600.00....

when you fitted the new lamp did you reset the lamp burn time??

if not the tv still thinks it has the old lamp fitted!!! clever these tv's

Hi
Usually, if the red light is flashing and you get no picture, that means that the lamp life cycle is finished and you'll have to get a replacment lamp. the lamp has about 3000 hours of life (2 to 3 years under nomal use).

You can buy a replacment lamp from here

These guys are correct, you need a new dlp lamp. The lamp # for your particular television model is the TS CL110UAA.
