Sony Bravia KDL-40V5100 40 in. LCD HDTV - Answered Questions & Fixed issues

It sounds that the fault is with its main digital board. A start signal should come to the P/S board, from the main board, after the set is powered ON. Check whether this voltage comes to it. Refer to its repair manual for details. To get some details, http://electronicshelponline.blogspot.com/Pull up older posts.

Sorry to say but it sounds like your power supply is bad, although it is possible it is some other components in the TV because turning it off allows all diodes etc to power down completely. Unfortunately after a bit it happens again which leads me to believe again power trouble.

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.

Sounds like a T'Con [Timing Control] board fault. In most Sony LCDs, this board will be built inside the display panel. If so, no other; except engineers at authorized service center for Sony can do anything. I advice you to contact the authorized service center for Sony; to get it repaires. Gopakumar Gopalan Google

Check the output voltages from the main power regulator. You must have the voltage list to proceed. Check all the low voltages carefully. If you wish to get the voltage chart, and other details, check the site linked here. http://electronicshelponline.blogspot.com/ Pull up previous posts by its left sidebar, or type in the brand name and model number to of your set, to its search box, and press 'Enter' or view it in Mosaic / Timeslide option.Products powered by electricity should be serviced or repaired only by experienced professional technicians.

Actually this is a very skilled work. Products powered by electricity should be serviced or repaired only by experienced professional technicians. Any attempt to service or repair the product by anyone else could result in serious injury or death. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electrical shock. Instead, contact the nearest service centre.

Where and how is it connected, also a simple step is try to either hook the player to another set or another player to this set, try to rule some things out.l

Visit the site named 'Electro-help' for more details. Check this link and select the site. View it in 'Flip card' option, which can be selected from the drop down box menu at the left top corner or the display window. It will make search easy.Blinking codes for Sony and most of other brands of TVs are given in detail. Pull up older posts there. Sometimes, ads by the side and bottom of each post might help you to find the details of livability of spare parts too.

I have the same problem did you ever find a solution

I see so many here with no sound/nopicture issues:ISSUES: 1. IF sound main fuse/s are good.2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.4. Be safe and if you do not know what you are doing don't open the set.Answers to issues:1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.

Consult the owner manual or call Sony customer service for detailed assistance in clearing this issue.

The first question I always ask is - Is it plugged in? next is the outlet "Switched" or operated by a wall switch. Some outlets can be wired so the top outlet is switched and the lower outlet remains on all the time. You might have a bad power cord - not common but can happen. If these don't work try putting tape over the "remote eye" on the front of the set. There may be a strong source of IR in the room. (bad light bulb or sun reflection on the Eye) The set may just be dead.

Yes,France and UK are in Europe an both have the same tv signal broadcasting out channels that PAL frequencies output.So yes.

Yes,this causes are bring it on by a board that call the T-CON board.This T-CON board it is slowly shorting out and slowly dying to bring these vertical lines up and showing up onto the tv LCD screen panel.This T-CON board jobs are to control and filter all the tv pictures pixels before it show up on the tv LCD screen panel.This T-CON board sit in the middle at the bottom of the tv LCD screen panel.Tries websites like Shopjimmy.com,Ebay.com to buy a new refurbish T-CON board for the replacement.

LCD Screen would cost you more than tv worth, a new tv would be good choice instead of lcd screen replacement.
Thanks.

Checkout the setup menu.sound off/on ??

Hello,

Problem is in either power supply or the Y-Sustain board.

The Y-Sustain is a relatively large board out of which go connections to the side of the display; it's therefore closer to either the left or the right side of the display, has at least one rather large heat sink on it and fat power cables connecting it to the main power supply.

Often there are fuses on that board - one or more. Check those.

if they are blown you can try to replace them, but expect them to blow again - usually the whole board needs to be replaced.


Hope this will work in solving the problem.....

Press the menu button on the side of the TV, not the remote, for several seconds.
