20 Most Recent Sony BRAVIA KDL-52S5100 52 in. LCD HDTV Questions & Answers

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.

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should troubles shoot. Contact any service technician. The circuit will differ with models and versions.
Type in the brand name of your device, in the search box [at the top right] of the display window and the Search will start at once as you type in, and will show you all the related posts. It will make surf easy.

Most TV's require to be set on channel 3 with the TV remote again I say with the TV remote then if you get a screen run the channel lookup command from the TV remote, that should do it for you. In addition make sure the TV is set to the correct AV input with the converter box remote, your ISP can help with that part

As long as you are getting all of your channels this is normal to have a delay between changing on HDMI.

Sony BRAVIA... | Answered on Oct 07, 2012

It sounds like your set needs servicing. Are the other inputs working? HDMI port failures are indicative of a problem with the main board.

That problem is usually have 2 causes..Its either power supply board or main board..

Please take this steps on how to determine the problem:
1. Open the back cover.
2. Check the power supply output...It should have 5vdc for the main board..12vdc or 16vdc for the audio and 24vdc for the back-light inverter..
3. If those 3 voltage supplies have encountered voltage drop...The problem could be on power supply board..
4. If the power supply output is normal..The problem could be on the main board...
5. If the problem is power supply you should check if the capacitors are bulged on the top and try to replaced it..If you can't do that you can purchased new power supply board..
6. If the problem is on main board there is no D.I.Y repair on that so you need to buy a new main board that fits to your TV..
Hope this solution will be helpful..

Thanks for using fixya...
