You would need the service manual in order to change the picture tube properly as there are dangerous voltages stored inside the tube also the tube would have to be set up properly as well. You can get the service manual for your model at the following link. They will email it too you right after purchase. Heres the link.

The lines you saw, i;m sure they are the ones called retrace lines but know the failure could be located on the red CRT board. Most likely the video amplifier is defective and not necessarily the CRT.
What is the model number of your TV?

YOu have convergence issues. Ok first question. IN your setup menu do you have the convergence option/ if you DO not then it can be a specail fusable link. fl231 if you do. next question do the picture bow in at the middle. if you do then it possibly a convergence power supply issue. next if you go into setup convergence does the crosshairs adjust up or down left to right on both blue and red. I if so then theres is a chance that it can be a convergence adjusment or a amplifer problem AS always THIS SET CAN GENERATE LEATHAL 380 VOLTS EVEN WITH SET UPLUGED SO BE CAREFULL.

Go to JVC website for a copy of the manual. I suspect the projection lamp is bad.

Flashing green power light


If the model indicated here is right It could be in the power supply and this model sometimes fails where light just blinks--that could be also convergence issue--in this model there is a way to disconnect the power going to the convergence board to see if set will then turn on.

Why is the blue light on front blinking


My answer is based on the model number here-AV-56WP74 or similar--blue light blinking is shutdown to protect the power supply in the set.

A few questions you could answer:

before this happened was screen red (too much) or had colors skewed or a little 3d looking?

The most common issue on this set if that is convergence and it can easily escalate to where it shuts the set down and blue blinks constant.

There is a simple way to confirm or deny that issue--Got someone willing to try that? Set will be unplugged and entire front grill under screen removed to try it(I can tell you how and what to do)

If no skill at all--consult a shop--if want I will answer questions or comments you post on this page--(add a comment button)

Projection sets have two very common problems outlined below.

The first common problem is convergence

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. The TV can also shut down when the convergence starts to fail.

Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith, RCA and others.

You can get more information and a DIY convergenece repair kit with instructions from TV Repair Kits using the link at the end of this article.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped or bowed
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture
