Black/Green Distortion - Picture Quality - Wharfedale


This is no solution but a point in a probable direction.

A tech guy told me ALL the LCDs they have seen in their repair shop have "swollen" capacitors, this is due to voltage instability. Lowering the internal voltage regulator and replacing the swollen capacitors (which eliminate noise) apparently restores the LCD to new working quality. Without actually "seeing" my problem the tech said that should repair it. I have not tried this yet but eventually will begin that way.

I have a Panasonic Viera 37" plasma TV which is nearly 3yrs old. Picture input is from Sky HD via hdt lead. Most times pic quality is brilliant on both HD and none HD. However I occasionally experience...


This is a fault definately. I have run into this with Samsung plasma tv's and find if you do some electrical adjustments you can usually remedy the situation. Sometimes though, it is the panel going bad or a board. Do u have any pictures i can see? Also keep in mind that if you have a DVM you can make the adjustments yourself. Good luck...GURU JAY

I am told my Hitachi 61SDX01B (UltraVision/Ultrascan) has "Green Geometry"


Sounds like a convergence promblem.

Here are some of the most common symptoms of a convergence problem.

Screen looks 3D
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed in or warped.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence or magic focus section.

Try to adjust the convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

Its a fairly easy fix on the Hitachi sets.

You can get a repair kit that includes all the parts from www.TvRepairKits.com. The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc.
Everything you need to fix it yourself.

The problem is called green geometry.There is nothing wrong w/the green pix tube.It is critical to get the green geometry

accurate because the red and blue convergence overlays on

the green.If you have more than an alignment issue,that will need

repair before adjustments are attempted.
