Question about Sony BRAVIA KDL-40V3000 Television

1 Answer

"Upgrade" of Backlight Panel

For a Sony KLV-32S310A, is a backlight panel "upgrade" possible? If the backlight inverter or backlight "power supply" has failed, should only the backlight "power supply" or backlight inverter be replaced? If the problem is the bad lamp(s), should the bad lamp(s) be replaced only? OR should the whole backlight panel be replaced? OR should the Bravia unit be replaced already?

I have a Sony WEGA KDE-42XS955 that takes 5 minutes for the picture to appear. Once it appears..works great! If I just leave it turned for it will work fine. Any idea what board needs to be replaced?


The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main 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. Pull up older posts. http://electronicshelponline.blogspot.com/ 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.

Sony Bravia flat screen TV when turned on has black screen. Green light on the bottom is lite up, electric plug is plugged into house socket, no picture only black screen.


If audio is OK, the fault is with its backlight section. If audio too is absent, the fault is with its digital main board. If you wish to get more details visit the site linked here. Pull up older posts.

I have sound but no picture on my tv


This is a popular question. Most of the time you either need to make sure all connections are not loose or just need to turn off your tv and receiver and unplug. Wait for 1 minute then reboot.
I recommend this short video as it walks you through some diagnostics for other possible problems.
