3 yr old Sony KDL-37XBR6. We noticed that picture was slightly dimmer than normal for about a week. Then the screen went abruptly and completely blank. We still have sound and can change channels, but no picture at all. In a dark room you can see a slight glow on screen. This is hard to see in daylight. Tried shining a bright flashlight into the screen to look for image, but could not really see anything.

Pull the power plug from the wall, and replug.

The repair / replacement procedure is not extremely difficult if you have some basic electrical safety knowledge and some basic electronics / mechanical repair skills.

You will need to unplug the power cord from the unit, lay the TV screen side down on something soft and flat like a bed if necessary, and then remove the rear access panel or the entire rear cover as required in order to access the circuit boards inside.

When you remove the rear cover and access the circuit boards inside, just check the part number that is printed right on your circuit board and confirm that it exactly matches the one provided in the online listing or the replacement part you have. Also make sure that any part you order is labelled "TESTED WORKING" in the condition description. Any part with a condition description of "AS IS" is probably faulty itself as well.

Then unclip and remove the various electrical wire connectors leading to the power supply circuit board. Then remove the screws securing the circuit board to the TV frame and then remove the power supply circuit board. Be sure to avoid touching any large capacitors on the circuit board which can retain a nasty charge even after the unit is unplugged.

Then just screw in the new circuit board and connect all the wire bundles to their appropriate connectors on the new circuit board and then replace the rear cover. Then plug in the power cord and test.

I can't tell from the manual if this particular model has the smaller removable access panel on the back or not. If it does, you will see a few screws around a removeable center section of the rear plastic enclosure. Just remove these screws and the smaller plastic panel should unhook and come off allowing you to access the main circuit boards inside.

Otherwise you will have to remove the entire rear plastic enclosure. This is not exceptionally difficult, it just means you will have to remove many more screws. There will likely be over a dozen small philips head screws all around the perimeter of the rear enclosure holding it to the TV frame. Depending on your setup it may be easier to lay the screen side down on a soft flat surface like a bed to do this, but most times this is not necessary. Just be sure not to press too much on the LCD display panel itself or allow it to get scratched / gouged / bent / poked / etc.

Here is a link to a picture of what a generic LCD TV looks like with the rear panel removed revealing the major circuit boards inside:

And here is a link to an interesting Youtube video which shows an LCD TV being disassembled for spare parts harvesting:

Although unlike the video shows, you might want to use a manual hand screwdriver to remove the rear enclosure screws if you do this yourself for the first time.

Here also is a link to the SHOPJIMMY.COM parts supplier website which has all the available replacement parts (circuit boards) for your model of TV:

Just click on the appropriate part number under the POWER SUPPLY section to show a picture of the board as well as details and price. Unfortunately all those different power supply circuit boards appear to be currently OUT OF STOCK there, but you can probably find the one you need elsewhere online or on Ebay by searching for the exact part number listed on your particular circuit board.

Please comment back here to this page if you have any details to add, have any questions, have difficulty accessing the links, or just require further general assistance and I will respond as soon as I see it.

I hope that was helpful to you, good luck and take care.
