    Thank you for you post. I do notice that the Red and Green do light up faintly for a moment then go off together followed by the Blue one a few seconds later.

Hi.

If you get a faint blue picture, then two of the three CRTs (projection tubes) are not lighting up.

This may happen for different reasons:

1 The power board is defective.

A faulty power board that is not giving right value on higher voltage lines to CRT power board can cause the problem.
Power board must be tested at component level.

2 Two CRTs, or Two ballast boards have failed at the same time because of a wiring problem.

This is rather unlikely, but still possible, voltage to CRTs and Ballast must be tested before replacing power board.
The control board must also be tested, since ballasts are not directly connected to PSU.

The TV must be tested by a trained technician before eventually replacing the power board.

Here all parts for your model.

Here power board: SRP-9001A-M2-R.

If you want a quote on repair, then call the number listed on the owner manual.

Regards.

    The problem is not common. Normally the TV will go on protection from start , with led blinking.

    If there is a faulty part , that is probably a faulty PSU.

    The TV must be tested internally at component level, there is no error code, and the fault may be caused even by a broken contact.

    The three tubes have each a ballast board, that is an high voltage board that supplies power to the individual CRT (red , green, blue).
    It looks like the PSU does not supply power to the three ballasts, for this reason I think that the problem may be PSU, but the PSU must be tested first.

    Regards.

Color changing


youve most likely got an issue with the CRTs one most likely which cuts out and back in randomly. Try removing the rear cover and look in at the three crts while its doing that and see if you can see one or more keep turning off and on.

How do I clean the inside of the screen?


Don't even try to clean the inside of the screen on the mode indicated here, av 56p575.

If the picture is darker remove rear cover and reach up with a lens cloth and clean the three large lens---they are your light source.

What is your reason to want to clean the inside of the screen, I am able to offer advice there.

I think the green is out. No matter how we play with the settings we cannot get any green to show in the pictures. What can we do to fix it? this is a JVC av 56p575


This is a CRT projection monitor - the image is generated by 3 separate tubes. If the green colour is missing then either the tube has failed or the video circuit to the green tube is faulty.
You must find out which by measuring the voltages on the green tube - if they are ok then you will need a new tube. You could find one here - not at this moment, only a blue one is available now

Hi there,

Please find the link below which will take you to a site called Diplodocs.com where you can download your user manual for free. I have set the link to take you to the correct page for your manual. On the web page you will see a PDF file on the right hand side of the screen, under the PDF file it will read 'Download the complete
user guide (4132 Ko)' If you click on this it will take you to another screen where it will ask you to rate the JVC AV-56P575 where you just click on the stars (rating 1-10) only once you have done this will it allow you to download the PDF (save it to your desktop) once saved you can open the file (If you have a PDF file reader such as Adobe). You will then have the user manual for your tv. I have scanned the file and it is ok but I recommend you virus scan the file also before you open it but I use this site all the time and have never had a problem.

Hello, I have no sound on JVC AV-56P575. When


I have had the same problem. It usually happens when changing from a non-HD channel to a HD. It has been doing since the purchase of the TV. Instead of going through the headache of a service call, I have been turning it off, wait a couple of minutes and then turn it back on. The sound returns and the issue will not repeat itself for at least a couple of weeks.

Nothing but a blue screen


Good day.

No fuse was blown in this case. It has something to do with the filter capacitor along the screen supply to your crt circuit.
Have it checked by the repairmen since the problem is internal.
