Re: Enquiry

Does the screen seem like it's stretched top to bottom? Or does it have a wave like appearance when the object moves on set? Either way some resistance has changed. You may look at board and see a chardd or burnt spot near a resistor. You shoud have value checked and replaced. Also look for any caps out of line or distorted.

JVC Hd56fn97 56-inch 1080p Hdila Rear Projection Tv with all blue color green

Talk to JVC as I have suggested and this is likely a known problem: loss of any color, picture upside down etc requires a upgrade to correct and I have seen about twenty sets with their name like this with this kind of problem.

JVC AV-56WP74 Colors quit working or went out of balance.

Guns or CRT are probably ok. Your TV needs a convergence IC STK392-120 replacement. Lamp are used on LCD and DLP rear projection TV's. Color wheel are for DLP's. :)

Jvc 52 inch tv. the picture on the upper left corner drops and is discolored

Hi if your tv is a Dlp or Lcd it will be a problem with the light engine.Basically there's 3 chips green,blue,red that create the image and colors.When they start to go bad or melt you will get color discoloration on corners on the center.You will need to replace the optical block ,you can find it on or ebay .Have a blessed day!

If it has been moved or bumped recently the sound you are hearing is the main HT lead that has been displaced. TGhis is a blasck lead with a rubber disk surround at its end that fits into the picture tube. Do not touch without turning TV Off and using rubber gloves to reinsert.

Tv comes on then goes black power light blinks on and off modle # JVC AV-56WP74 56

Check the coils on the main board. Coils mean round ferrite donuts (1 inch or less) with copper wires on it. I have seen this come out.
if not check convergence amp ic's

Jvc tv picture quality

sounds like your crt tubes...meaning Red, Green and Blue are out of alignment...or possibly 1 of the crt's is burned out.
