Panasonic TX28 Widescreen Query...
Hi
Just bought a new Panasonic TX28PM1 - and the picture quality is great (for my purposes!). My only query is, when I power up the TV from cold, as the image appears on screen it kind of phases between green and red, before appearing normal. This process only takes a second and settles down to a crisp image afterwards. This is my first "new" set so I don't know whether this is expected or not. Panasonic advise that it's part of the "de-gaussing" process and is normal - but, thought I'd get other opinions.. Thanks for the help.. Ali. |

You may be seeing several things.
The degaussing process can cause a visual colour shift, until it is finished. When the CRT comes up to operation, the automatic circuits have to perform the colour tracking adjustments to meet the reference that has been set up in the set's firmware. -- Jerry G. ===== "Alison Hannah" wrote in message . uk...

Is it a normal thing for new CRT's to degauss on startup (sorry if I'm missing something glaringly obvious here!). It's just I've never seen this on other similar sets, although they aren't as new. My folks have an older Panasonic 32 widescreen which doesn't show the same symptoms on startup.. and always when it's cold... Don't know whether to take it back or not - I may just get lumbered with the same problem on the new one... Ho hum.. Ali. |
