There is a problem with the convergence circuit that the focus won't fix. You will need to either resolder the pins on the convergence ICs or replace them. These are large black ICs attached to a heatsink and are marked STKxxx. Resolder first. If that does not resolve it, replace the ICs.

SOURCE: when i turn on tv the screen is turning green

Solution:
Your TV has a convergence problem. Here are some of the most common symptoms.

Screen looks 3D
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed in but stationary.
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 red and then the blue 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.
You can get a repair kit that includes all the parts from www.TvRepairKits.com.
They have put together a kit for the Hitachi TV sets.
The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc.
Everything you need to fix it yourself. Its a fairly easy fix on the Hitachi sets.

SOURCE: Picture is fuzzy for the first few mins after turning on

This may be an issue with your color wheel where it isn't spinning up to speed at first but finally does after the 2 - 10 minutes. Fairly common in DLP TV's.
This could be fixed by a qualified Hitachi Servicer.

I have anew Samsung 55 inch model code ue55h6500akxxu but it will not store my settings as soon as i turn tv off an on again it goes back to custom settings


This is from an article I found online:

"It's likely that the television is in Shop Mode. The symptom would be that your settings are defaulted back to the out-of-box settings?

Try holding down the Menu button on the TV (Not remote) for 12 seconds.

OR

Try pushing the volume button up once, let go, and then hold down the MENU button for about 12 seconds.

You might see the screen flicker, and that's okay. Once you've done that, you should be able to program your settings and they should stay.

Why does my Panasonic Viera VT50 have no picture and red led blinks 3 times


First thing, check the HDMI input and make sure it is firmly connected, same for the power cable, obviously. My Samsung goes similarly nuts if it detects no signal from the currently selected input but after 1-2 minutes it eventually stops and I can change the input source.

Rca 42in full hd lcd picture flickers


If the picture on your TV flickers, there may be a simple fix. Here are some possible answers and suggested solutions:

1. Your set-top box may need a simple reboot. Unplug the power connection to the set-top box for about 30 seconds. Reconnect the power and turn the set-top box back on.

2. Check all of your cables for a loose connection by tightening each one with your fingers.Flickers can sometimes be caused by bends in rigid cables, too.

3. If your picture flickers to a black or blue screen, you could have a bad set-top box. Contact your cable or satellite service provider about installing a new one.

4. If you still have audio, the flickering could also mean that you have a failing backlight.

For additional troubleshooting information, check out the chart at TV flickering for more solutions. I hope this helps!

Samsung le40f71bx picture flickers on and off with hd source


I've had similar for a long time, now the picture only lasts a few minutes or seconds. Have to turn the TV off, wait 5 minutes, turn it back on. That's with Sky HD. Used to be the same with SCART but I don't use that any more, and I get it with the Wii on Component. However HD DVD and Blu Ray players are no problem!

See my post here - http://www.avforums.com/forums/lcd-led-lcd-tvs/1622157-samsung-f71-flashing-pattern-fault.html

Way out of warranty but really just need some repair expert to tell me what needs fixing. Taking the cover off there are very few components and look easy to replace, and seen some on ebay. A fix from Samsung would be vastly in excess of the value of the TV.

Samsung HDTV model HLR5067W screen flickers when some commercials play other commercials are ok when viewing. Could this be my HD set top box or a cable?


If the TV works well with your dvd and regular programs there are no issues and the flickers due to commercials can be due to excess signal strength or even poor control from the set top box.
Try with another set top box to confirm as some of them can process noise which can cause this issue.

Mitsubishi VS-55609 distorted Picture Flickers


Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs. To get fixed either call in a local TV repair company or goto sites such as Tv Repair Kits to get a repair kit with instructions. Here is there link.

Bad picture


Sounds like a dry solder joint. When the tv is on for 4/5 mins the crack warms up and the gap spreads. When you turn off it cools and when it warms up it starts again.

TV picture flickers


If your DVD player is separate from your tv, you might have a loose cable plug or connection. Depending on the type of flicker you have, a vertical circuit loose connection would cause this. If you could connect it to a cable or antenna it might tell you where the problem is located. A faulty circuit in the DVD might cause this too. Stargazer
