There may be 2 issues going on here, hopping fellow techlore members can help me sort through them
1. While watching tv the screen will flash very bright green, then go off. The standby light flashes 8 times . turn unit off, then back on and it seems to work for a while, this issue is pretty intermitent.
2. There a red bow shaped lines on the top and bottom of the screen that are particualy noticalbe durring dark scenes but even more obvious when swithing from one source to another.
Not sure if the above are related or seperate issues.
If someone could point me in the right direction it would be most apprectiated and if someone could send me the repair manual for the Sony KP46wt500. [email protected]
Thank you

part one, do you hear an arch (snap when this happens) ? could be the green crt.
Part two, this sounds like you are seeing retrace lines this also could be a crt (red) but you can try turning down the screen to get rid of this, the screen control is under the front pannel, remove the gray lower part of the tv, then under a panel behind this gray pannel, the controls will reside, change the red screen control.
This control block could be malfunctioning causing both problems, but i am not sure. you may need to have this one diagnosed. There is no easy answer to your problem
