    Ghosting occurred all at once while watching tv. It occurred when changing a channel and has not corrected. I turned power off at the strip but it had no effect. I checked picture from DVD player but it was the save so I know it is not the cable service. Ghosting is mostly in red. Is it repairable at a reasonable cost?

I got one likes that. I have fixed mine by changing only one IC 8001. After my TV operating about 20 days, the problem come back.It might be the quality of the IC STK 392-56. Because IC production made by Sanyo ???

I have a sony projection tv kp-43ht20 and the picture has gone pink. Can you give me an idea what has happened? Is this a fixable problem? I can't afford a brand new tv at this time. Thank you for your...


Sounds like the convergence is out of adjustment....moving the set can cause this as well as components chaging value with age....The kp43ht20 is an older set and may not have the alignment setup in the menu as with the newer sets...but you can go thru the menu to find out...if there is one, then you can try to align the convergence...usually there will be a crosshatch on the tv...when aligning convergence there will be a blue setting and a red setting...you want to select red first and try to get the lines lined up as close together as possible on the red adjustment..then you go to the blue adjustment and do the same...the outcome should be as close as possible to white when everything is lined up properly

Green ghosting on the side of images, sony kp43175


this could be caused by a magnet thats too close to the tv, like in an unshielded hifi speaker. if not, then a degausing component if faulty and needs replacing by an engineer.

Sony KP-43HT20 Projection TV


5 times blinks is error code for No Good White Balance and you said that picture is very green.
As you know TV is approx 7 years old so it needs RGB gain adjustments.
If you are TV tech person or know about TV repair, let me know to guide you further. Or contact local TV repair shop to fix it.
