I have a JVC HDTV model AV-65WP74, i had my tv on overnight, woke up this morning i found the colors on the tv kind of funny and the tv is also showing double images. Please help. What to do?

The convergence ICs have failed. You can get the JVC AV48WP74 - AV65WP74 convergence repair kit from which has the ICs and resistors plus the CD with detailed repair instructions.

Where can i get the diagram for my TV to fix the convergence, i have a JVC AV-48WP74

You do not need a diagram, I can tell you all that is involved--it entails getting the board with the parts out and replacing both chips and any bad resisters.

See attached photos: they are of the board that needs to be removed.

This is a easy set to get at the parts and they are soldered in, so you need to be able to solder etc.

Let me know and I will be happy to assist here.

IF the pictures or this information told you something you did not know rate this solution as very helpful as I do this here for free.

This kind of picture problem is due to failure of convergence out ICs, please replace convergence out ICs in tv to get it fixed.
If you are handy with electronics stuff repair and can replace parts in circuit board with proper tools then can replace above said ICs by yourself or ask local tv tech to repair your tv.

I have a jvc av48wp30 tv and need a wire diagram

Looking the convergence board from the side of the resistors (The chips will be behind the resistors), you have from de left to right:

1.5 ohms, 150ohms, 220ohms, 2.2ohms, 3.3 ohms, 220ohms, 1.8ohms, 220ohms, 150ohms, 150ohms, 1.5ohms, and dispose horizontal in relation of the other resistors (the one near to the Ic is 2.2ohms and the other is 220ohms).

Hope this helps...

Please help me fix my tv

You will need 2 new convergence ICs STK392-110 also the 1.8 ohm resistor and the pico fuse usually burn with that model. the ICs are located on the small board located behind the speaker grille and access panel in front. Easy repair go to the following link and you can get replacement ICs and any other part you need. And they provide installation instructions as well as free on line instant meassaging for all customers when they do thier actual repair. Heres the link.

I've found several bad solder joints on the neck board of my JVC 32' leading to the exact same issues as yours. Inspect the Driver resistor solder on the neck board.
