My Sony KP-61v90 has just stop showing the picture from the cable input. I can hear sound but I don't get any picture. I can see video from the video inputs but nothing from the cable port. What could be the problem?

Thats an issue with the U board ( inputs) You can get the replacement U board from www.tvrepairworld.com under the sony circuit board catagory

Hello, It sounds like the deflection circuit is faulty. Usually,but not always caused by a problem with the switch mode power supply. It could be as simple as a capacitor or zener diode. Either way unless you are a technician I would get one to help you. Shouldnt cost any more than around $100-$180. As far as the pix goes,that sounds like the lamp they use to project images,around $400 fitted. Hope that helps.

If it still has the warrent you can return it and they check it out.

see this link. Your question is number one on the list of FAQ for this product http://esupport.sony.com/US/perl/news-item.pl?news_id=256&mdl=KP61V90

replace the vertical output IC that should take care of it.

On this TV there is only one input for any HD resolution. Input # 5 is the component input i.e. red/green/blue cable. Just get the correct cable and match colors from cable box to TV this will allow the TV to display 1080i resolution ( only one this TV supports ). FYI you will also have to connect the red and white cables to the appropriate inputs to get any sound because red/green/blue connectors are just for video display not sound. Once your connected you'll be able to access video # 5 be sure to set your cable box to 1080i resolution also. I hope this helps later J.

Sounds like it is the signal source (cable box or satelite example) also try different inputs, dvd, vcr

All tvs will work with change over as long as you have a cable box, or satellite box if you dont have cable you need conversion box radio shack has them 39.95 and will supply discount you could get them for free.
