SOURCE: my sony bravia 52ex700 tv turns on but there is no picture help...

Try changing the input device to something you are sure, works such as a DVD player.

Switch off TV manually, switch off power, remove plug and retry after 48 hours.

If problem persists, please refer it to a qualified service technician.

I have a Sony bravia kdl-52ex700 and TV no longer recognizes hdmi plugged in. It won't recognize direct TV or Blu Ray player. I tried a factory reset and still not working.


I am assuming you have set your TV to the correct component in the TV's menu. If the hdmi is bad there are 2 options: 1) have it repaired and expect that this may cost almost as much as buying a new on on Black Friday or 2) set it up to run on s-video if so equipped. You won't get the best picture but it will be close.

I have a Sony 52 inch LED TV Kdl-52ex700 and the picture went out it powers up fine but the picture displays a lighted black screen.still get sound.any help would be appreciated thank you


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 trouble shoot. Contact any service technician. The circuit will differ with models and versions.

Kdl-52ex700 powers on but black screen


It's a faulty television. More than likely something in the mobo has gone wrong. I'd recommend returning the TV for a new one if you have that option, and if not, send it off to your manufacturer so that warranty work can be done on it.

Where possible, please refer customer to Sony Website -(or ) and search for relevant model to download correct update. If the unit is in Workshop, please perform update as per Instructions.
