I also have the red lines on my JVC aw-56WP74 model TV. I was told if I replaced the red bulb(lens), then I would need to replace all three bulbs together; otherwise, the red would be too powerful for the two older green/blue lens. Thanks for the response.

Someone offered me a jvc hdtv av-56wp74,and one person said just the bulb in the lamp has to be replaced;then when called jvc they said i had to by colored tubes for 300.00 each,,,,who do i believe

The tubes rarely fail in this model so it may be a convergence issue instead. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed.

Here is an example video

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. :)

How do I change the rear break light?

How to Replace a Tail, Brake or Reverse Light writer_avatar.gif Contributor By eHow Contributing Writer Article Rating: stars_3_20.gif (70 Ratings) replacelight_hero.jpg Fix that broken tail light. Replacing a dead bulb on your car is almost as easy as replacing a light bulb at home. Perform this simple maintenance and avoid the hassle of receiving a citation for a missing brake lightmag-glass_10x10.gif.
jQuery('.intro .thumbnail').each(function(i,e){ jQuery(e).find('img').one('error',function(){ jQuery(e).remove(); }); }); Difficulty: Moderately Easy Instructions Things You'll Need:
  • Rubber Gloves
  • Automotive Light Bulbs
  • Red Tape
  • Cleaning Cloths
  • Rags
  • Screwdriver Sets
  1. Step 1 Determine how the bulb is accessed: On some models the lens (the red or white plastic part over the light) must be unscrewed from the outside, and on others the bulb is accessible only from inside the trunk. If there are no screws on the lens, you can assume that the bulb must be replaced from inside. Usually there will be a plastic cover that must be removed in order to access the bulb. There may be tabs, screws or small knobs that hold this plastic cover in place.
  2. Step 2replacelight_2s.jpg Unscrew the lens on the outside, or take off the plastic cover from inside the trunk, to reveal the bulb.
  3. Step 3replacelight_3s.jpg Unscrew the bulb. You'll have to push in and turn at the same time.
  4. Step 4 Take the bulb with you to the auto supply store to help you find an exact duplicate.
  5. Step 5replacelight_5s.jpg Clean the connection with a wire brush and/or wipe it clean with a rag if there's any corrosion.
  6. Step 6replacelight_6s.jpg Screw the new bulb into the empty socket. Again, you'll have to push in and turn simultaneously. Line up the tiny raised bumps on the base of the bulb in order to screw it in.
  7. Step 7 Replace the lens or the plastic cover.
  8. Step 8replacelight_8s.jpg Test your work by stepping on the brakes and turning on the headlights while a friend watches the new bulb to make sure it lights up.
  9. hope this will help you

JVC AV-56WP74 self check question

Each picture tube (red,green,blue) has a magnifying lens assy that sits on top. On each lens assy is a manual focus adjustment with a wing nut that tightens it. The image bounces onto the mirror and shoots it onto the front screen. If you're not a technician then I don't advise you to do this adjustment. You could touch something in the high voltage by accident.

Convergence problem

I have this exact model TV, and my red bulb was the primary culprit. I almost had it, but then a lot of fluid came from underneath the bulb? I had to turn it off in fear of electricution. Ended up selling the TV.
