Green Area appears in lower part of screen

A green area appears in the lower part of the screen in the middle of the TV. This spot is getting larger with time. It is about 6 years old now and way out of warranty. Any suggestions?

Re: Green Area appears in lower part of screen

Wayne, is it there as soon as the image comes up or does it have to run awhile before it appears? Let me know,

I have a Panasonic pt-44Lcx65 tv and it has this blue snowflake or blue star looking stuff all over the screen area and now within the last 2 weeks or so it developed this yellow or green large circle area...

Is the tv new? On which input is set your tv? Change some cables they are connected to your tv (like the HDMI) and see if you can get a clear image.

Panasonic pt-61lcx65 green spot

This may be a main board issue if the green spot moves. This is repairable. This may be a panel issue if it does not move and it is present on the panasonic splash screen and if it affects the osd menu.

Screen has a area on left center area that is greener than the rest and apears the shape of a large ink blot

Do you have a speaker or some other electric device by the TV where the green spot is? If so remove it and if the spot is still there try playing a DVD and if it's still there unplug your TV for 5 min., plug the TV back in and if its still there your TV is the issue.

Light green and pink spots on my hd tv!!!

Tiny particles of dust on the light engine lens can cause this (and was a service call for me about a month ago), or possibly the expensive light engine.

Hitachi Television Yellowing on the screen

Suggest you call Hitachi and complain. There is an issue with all projection LCD tvs (not just Hitachi) was that the light engine assembly did not have enough vents for cooling. This translates in a green or yellow blob that starts small and grows larger because the LCD screen frame starts to deform with the heat. Guess they did not test with young kids in the house and the tv on more than it is off :-). In March I managed to get Hitachi to pay for the part and I paid for the labor to get this fixed (out of warranty). The new light engine supposedly is better at cooling though I do see a faint 1/4 inch band of green at the bottom of the screen. Blackburn Electronics in Anderson IN has fixed many of these in the Indianapolis area.

Green Area in Lower part of screen

Some Hitachis have developed bad connections on the convergence output IC's (locations IK04 and IK05) You could try and resolder the IC's but if you are in it that far you are best to replace both. The generic part number is STK392-110

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 The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc.
Everything you need to fix it yourself.

Here is what I was able to find out about your problem from sony: This issue is usually caused by some type of nearby magnetic interference, such as unshielded stereo speakers placed too close to the TV. These spots can be small or large and will normally be red, green or blue, but sometimes appear purple or pink. They normally occur on the sides or corners of the screen, but can also appear in the middle. To resolve this issue, move any stereo speakers or other electronic devices away from the TV; a minimum of 2-3 feet is recommended. If the situation is not remedied immediately, unplug the power cord of the TV from the electrical outlet for 20-30 minutes; repeat this process one more time if the issue is not resolved the first time. If the issue is still unresolved, service may be required. The Sony® eService Web site at can assist you in obtaining service from a Sony Service Center or locating a Sony Authorized Servicer in your area. Hope this is helpful:)

Red spot in the middle of the screen

You most likely have a burn in on the surface of one of the picture tubes. What you need to do to confirm this, would be to take off the front screen, and with the set turned on, look directly into each one of the lenses, and see if you see a mark on the green or the blue tube. if this is the case, and I am pretty sure it is, the picture tube will need to be replaced, but this set is not a young thing, as the green faint lines is most likely a bad capacitor in the screen drive circuit. If the picture tube is indeed burned on the surface, most likely be better off buying a new TV set. Good Luck
