Hi there

Sounds like the lamp is going , but it could be the Ballast as well ( lamp's powersupply ) Rather have a certified technician look at.

Picture is very dark on all channels. Settings have not changed. Do I need to replace the bulb?


You may need a drive PCB. This PCB can cause the picture to be too bright, no brightness or picture too dark, intermittantly or permanantly. Do check the bulb though and see if it is foggy looking or dull especially if it has not been changed. Thanks for using Fixya.

Picture getting dark


My jvc 27" tv was so dark I could hardly see any night scenes, even with the bright all the way on. If you push the sleep button, let go, then hold down the video and display (together), the service menu will come on. Scroll down to #7 (too dark) and adjust the brightness there. Works immediately. Good luck.
