Sony BRAVIA - Recent Questions, Troubleshooting & Support


The antennas on most TV's are small and so moving the TV to a nee location may have put you in a new place in the house with even less signal. There are TV antenna signal amplifiers you can buy and for $50 or less you should be able to get something half decent that will boost your signal. Are you not getting any channel's now? Because you should still be able to get at least something in the new location. I'm just asking if you're getting any channels in hopes you didn't damage the TV while moving it?

Check all fuses. If you have power going into the power supply board..but none coming out of it...I think you have found your problem. Get a new power supply board.

I have never heard of a warm-up problem on a digital television. Unlike the old CRT TVs and monitors, digital panels don't have to warm up. I would go with the TV repair persons assessment that you've got a bad panel.

There may be a "Power saving" feature on the TV. Check in set-up and adjust time for auto shut off.

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 ResetF (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.

Test the power supply voltages after it shuts itself off, mainly the PSON voltage as that will determine if its a main board issue or power board

Hi there,
If you haven't done so already, check that the cable between your tv and digital cable box(probably HDMI) is secure at both ends. If it is, try a different cable and/or different port on your tv if you have more than one. If the issue is still there after you've tried these options it's most likely an issue with either the digital box or tv. I would contact manufacturer at this stage for advise and possible replacement of tv or box if they are under warranty.
Hope this helps.

Fault in the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. 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 power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
