Do you have a color bar generator?
Connect it to the composite input 1.
Go in the customer menu select the color adjustment and turn it all the way down and tell me what you see in the back ground image from the color bars.

I have jvc av-56wp30 all of a sudden the red in the picture is doubled. any ideas what that could be?


That sounds like a convergence failure. The AV48WP30 convergence repair kit from www.tvrepairworld.com should solve the issue. The kit contains the components and the CD with instructions.

My printer keeps printing greenish and blue/yellow


I fixed this problem for free with advice from the canon experts at the canon website, without them trying to sell me anything like a "plan" as your website has proposed.

Greenish/Yellow spot


Sounds like a scorch mark on the polerising filter, this can only be replaced by an engineer cost around £70 ($150).

How do i shut off the timer on my jvc tv


HI...I have the same problem and I am trying this today (Expert advice on forum) ... Hope it works!

Try unplugging the power cord of your T.V. for 1-4 hours for a "HARD RE-SET".
If T.V. does not work normally after this, then you'll need parts/repiars. (Internal circuit/voltage problem).

Best of Luck!
I will know if it works for me in about 2 hours!
Ciao!

Blue swirl on JVC - AV48WP30


you can get alot of different opinions on here but the best i can do is tell you to call a tv repair service to have them come out and repair the tv instead of trying to do it yourself and possibly making it worse than it allready is. with a repairman you get a guaranteee its fixed on here all you get is guesswork and you dont need that

Problem with the video inputs....


Your problem is the MICOM board. It is a standup board the plugs into the main board. It is basically the "brains" of the tv. It does all of your video processing,video switching, etc. It is also a very expensive board (around $400).

Kinda dead


techwolf, you nailed it, control board is bad, I have personally checked the tact switches and they checked good with Ohm meter but the meter lies, problem is module/board is kinda pricey and individual tact switches are not listed individually on parts list, you also have to be carefull that you get the correct one, there are 3 versions of your posted model #, AV48WP30, AV48WP30A, AV48WP30ME, be sure to check which one you have, should be able to order module here; www.partstore.com I have tried cleaning tact switches with "blue shower" but fix doesn`t last, have to change module out, good luck, BMW Rider
