Picture has become progressively dark 27'' TV JVC AV-27320

I have a 27'' TV JVC AV-27320 (dated 7/02) Chassis A110. Ever since we purchased it [new] in 2003, it has gradually become darker in the picture. Contrast and picture are adjusted to the highest level and the scenn is still getting progressively darker. If the scene in the movie is set in a dark place (i.e. inside a poorly lit house at night) you really can't make anything out, until the movie scene gets lighter (i.e. turns on a lamp or goes outside).
Would degoussing help (I do not have any discoloration or strange colors at the edges of the screen)? Is there a tube or chip that I can replace? There are no adjustments on the exterior. If I have to take it to a repair shop is this generally a simple and inexpensive fix?

Hello
Just make the picture status button on the remote control and get the display setting to its factory mode.

The VIDEO STATUS button gives you a choice of three TV picture display settings, including a
display of your own preferences.
Standard - Resets the picture display to the factory settings.
Dynamic - Heightens contrast.
Theater - Gives a rich, film-like look to video. (AV-27D303, AV-27D203 and AV-20D303 only)
Sports - When you watch a sports program. (AV-27330, AV-27320 and AV-27S33 only)
Press the VIDEO STATUS button repetedly to get these choices.

Dead jvc tv,av-27320


There is most likely the main power supply has several shorted parts in it, depending on how old it is, it might be worth at least an estimate. if you have homeowners insurance, you may want to concider reporting this to them. Good Luck
