Question about JVC AV-48WP30 48" Rear Projection Television

1 Answer

I have double blurry vision with green and purple/red splashes on all inputs (ghostlike)

Hi,

JVC av-48wp30 rear projection. It started yesterday but fixed itself and it was switching in and out between normal picture and one i am now describing but now it is staying with the blurred double colors on all inputs (even xbox). I have tried conversion page but it is doubled and blurry as well and i can even up the red and blue crosses but the green is way out of the area so i can't match it up.

Thanks,

This is a very common problem. If you want to fix this yourself you will need to be able to solder, but other than that its a very easy fix. Both the convergence output ic's need to be replaced (PN STK392-110). If you have a repairman do this for you it will run $300-$500 to repair. Let me know if you want to fix this yourself and i will assist you further.

Thanks

Blurry vision on picture


This is a very common failure on Projection TV sets.
Screen looks 3D
Colors don't line up
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed or warped.
You can see some example photos and find a solution here...

Looks like 3D Picture


You probly have a convergence cicuit failure. Replacing the convergencr IC's will probly fix it.
I recommend a professional repairman to
do it though. Particularly if it needs further adjustments after the IC's are replaced.

Double vision on tv with purple and green colors


Hello,

This television set, as well as most rear-projections, is prone to convergence driver problems. There are two large chips (STK392-110's) in the TV that need to be replaced, as well as some resistors that are likely damaged as well. Any competent TV repair shops should be able to repair this TV for 200-300 dollars. It is important to note that if the back of the TV is taken off without the proper prep., the Digital input (DVI) will be disabled permanently.

Hope this helps you...

Double vision


In this particular unit what you're describing is a failure of the convergence amps. This unit takes two STK392-110 Sanyo built Ic's and one or more 2.2 ohm/1w resistors for the yoke return. replace these and you should restore normal function after a little convergence touch-up.
It's not an expensive job in a qualified shop either. If any of this sounds a bit complicated take it in and have the job done.
Have a great day!

The convergence circuit needs repaired. I did the same job yesterday on this model. I not only replaced the convergence ICs, but, I had to replace a couple of resistors and a coil. The convergence alignment was minor after that.
