Test the voltage to the bulbs and see if it meets specs. May be a power supply problem.

Tv won't come on


Unless the arc tube is bulged--or cloudy--you cannot really tell by looking. This does sound like a bad lamp, probably # CL-110.

JVC HD-56FN97 when turned on blue light is solid,red ligt blinks a few times and goes out. My picture is very dark despite adjustments I make in the menu, any help or feed back apreciated.


The set does use a lamp for a light source and average life is 2 years or 2000 hours---many lamps before they actually fail get to be darker.

Turn set on picture is dark.. if I leave the TV on.. in several hours it's viewable.


I have seen several Samsung's including 3 that were only a few months old at the time where it was the lamp---one was so dim it was very hard to even see the picture or that the screen was lit.

Two suggestions here: One of course would be to buy and gamble and replace the lamp.

What I found in two of the three cases was when I removed the lamp the glass pillar inside it was "bent" at a angle from heat or a natural defect--in both those cases a new lamp cured this dim picture issue.

Set will monitor the lamp and if too dim may shut set off or even blink for a prolonged period of time.

If the lamp is over 2 years or age (average life) or was replaced with a non-Samsung lamp you are going to have to take the gamble to try another one.

Inspect the lamp---that pillar supports the filament and if bent the lamp is suspect at best.

Picture is very dark


its probably the lamp going bad. dark picture is a pre-cursor to failure. these lamps are supposed to last 2-4 years but for some reason the mitsubishi ones never do. you can replace the lamp yourself, and if it is going bad, you can cool it down, pull it out, and you will see it will look kind of bulged or white in the bulb part. instructions are in your user manual. if it is under a year old, mitsubishi should still cover it. if its just over a year, you can try to call them and complain and maybe they'll back it up. let me know if you need further assistance.

I Have JVC Nodel HD52G887 and no picture after I heared a pop sound while watching. Can someone come and fix it and how much?


You will have too replace the lamp, I have the same tv. The lamp costs around $200- they forgot to tell me the lamp runs on a timer and then when the time is up it goes and will need to be replaced. My tv is 3 years old and I am about to order my third lamp. Just remember after you replace the lamp that you go to the menu and "reset" the timer or it will not work even with a new lamp- all a money game

I have a JVC tv only 1 year old and the picture is getting dark.


Sorry to tell you but JVC is a well-known un-reliable brand and if it's cheap, probably even worse. U may have screen burn from leaving a games console on while plugged into the tv, even if its not showing the game, it will burn it onto the screen. :(
