My KDL 52w 5100 picture goes to various colors wih some lines not discerable picture. I loose the TV's Bravai Logo and the abilty to see the Menues. I have updated the software ( per Sony) and when I perform a factoy reset ( which can take 4 or 5 tries to tke effect ) I can get the picture back after I re- do the TV's initail set up... The TV will work for Hours...when the TV is turned off ( like over night ) it reverts back to the varius colors. Sony was not much help... Any suggestions

This seet should provide some diagnostic help. The standby light should be blinking a repeated count with a pause. Post that count here. Also, is there sound?

The above info will indicate the problem circuit which will then suggest the remedy.

Thanks,
Dan

More than likely the TV is in the "retail" mode which intentionally reverts to the "vivid" mode after a short period of time on the other settings, deemed best for retailer display puposes.

Follow the "return to factory settings" instructions found in the operators manual, pg 21 of KDL52S5100. Only the first half of the instructions are needed to put the TV in "home" mode, the 2nd slection to make after "language. After you have slected "home" I do not beleiev you need to any go further into the setup menu.

"Turn the TV on. Press and hold the "^" (up arrow) button on the remote and then push the "Power" button on the TV. Release the "up" arrow."

You should now be back to start, select langauge and home mode and then exit.

You now should be good to go and your picture mode selections should now stay put.

Sony has live tech help "chat" and I would suggest using them if this doesn't get it done - but I'm 99.95% sure this is your fix.

Testimonial: "Worked for me."

That symptom may cause by the main board or t-con board, I suggest you do software up grade first.

Yeah we have the same exact problem here. Defective TV....ours would correct itself after 30 mins, but now it's blurry all the time. I'm never dropping 2K on a SONY tv again.
