Blotchy screen my mothers 50" sony wega tv screen looks blotchy it's the red all over the screen you really notice it when watching football also the top two corners has blue blotchs she says she started to notice after the bulb got changed. any help would be greatly appreciated

i think yours projection t.v mirror are damage

take your tv with a good technision uhave porblem in your ckt there is one resistor has been damged so this porblem occers

Sounds like a cap or fuse has blown in the set, you will need to take the back cover of and have a look, check on the power board for any blown caps, you will notice them straight away if one has poped, also check any fuses that may have blown they will also need to be replaced.

Well this is an LCD projection TV and it sounds like one of the polarizer filter has gotten out of place so you are seeing at the top of your screen the unfiltered image of the LCD panel.
Will need to go into a shop to get repaired. Call and get an estimate of repair. Actually shouldn't be too bad of a repair cost.

It's the Digital convergence board. Sony has lost two class action lawsuits over this issue in the past two years. Contact Sony at 1-877-619-7669 and complain complain complain. If your lucky and you can talk to a supervisor, they can either get you a discount on the part or credit on a new set, or get you the part for free. I have been dealing with this issue with my own clients as well. Hope this helps

You'll probably need a new optical engine for your TV. Sony extended the warranty for some of their LCD projections but I think that the warranty extensions have all ended. Try Sony.com for more info.

Please intimate exact model of your Sony TV to find out reason of no power up.

hello it sound like convergance chips might be the trouble

shaun

I have the same tv.
On your remote push menu, then go to settings, and then screen. Put the auto wide to on. And keep the picture mode on normal, not the zoom or wide zoom. If its in HD it will fit the screen. If its not in HD it will crop the sides. This worked for me, hope it works out.

Does it look like a red ,green or blue roadmap?
