Hi,
I'm not sure if i just didnt notice it before because lack of xbox, but the sides of the image displayed on my Panny TX28DT2 seem to be torn from the sides of the screen. The edges are not square, and in some places the image is a significant distance away from the sides of the screen. Its almost as if the screen is made of material and the glue around the edge has come unstuck, not sure how else to describe the effect. The effect seems much more pronounced when playing xbox games, but even in DVD films any vertical lines towards the screen Left and Right sides are not displayed as straight. Any recommendations as to what it is, and what to do about it? The TV was 2nd hand but would rather not have to bin it.
Also unconnectedly it sometimes makes a buzzing noise from the speakers (even when muted), not sure why?
Thanks in advance,
Charlie

Could be an electrolytic capacitor gone faulty on one of the main HT/LT Lines?
Another job for an experienced Engineer.

GoodLuck!

cheers for the prompt reply! Could you confirm which of the problems you think was caused by the electrolytic capacitor? Being as the TV only cost me £50 on ebay i'm guessing its gonna be a case of once it dies dump it?

There could be high voltage from the p/supply or just normal loss of capacitance.
Some cap's need to be upgraded to a higher voltage rating.
e.g.10 microfarad @ 25v upgraded to 10 microfarad @35v

Do you know someone with TV repair Experiance that can have a look?
Otherwise it's the BIN!

GoodLuck!

Know someone yeah but unfortunately the TV is back up at uni up north, and the guy is near home down south, so i think this may be a good excuse to buy a new TV! Just have to try and raise the funds. Thanks for the help, was hoping there'd be a quick fix to keep me going for the moment. Ah well.
Cheers,

Quick update. Back with the TV now.
The screen tearing is much more pronounced when playing xbox games, than watching freeview (both external sources), and DVDs via xbox also seems to be less bad than Games via xbox.
Any ideas?

Yes...if you want it fixed call in an experienced TV engineer.
They are not d-i-y fixable and since you bought it second-hand for £50 I doubt you'd want to pay again to get it fixed.

I was hoping it'd be menu adjustable, as i know you can adjust the shape of a CRT monitor image, i presumed you could do the same with a TV, but as you say it was only 50 quid so might as well dump it.
Cheers for the advice.

If it's as bad as you stated in your original post I would say it's a fault and no amount of tinkering within the service menu will fix it.
