20 Most Recent Sony KDS55A2000 55" HDTV Questions & Answers

The problem has been there all the time, probably a dry solder joint or a bad chip, thats got worse over time & has now completly failed, its time for either a trip to the tv repair man, or the best option a nice new smart tv, i just bought a 42" for £199 why mess about.

Your t con board is responsible for the image on your screen. Your colors are all there but they are f---ed up in certain scenarios. That is the only board on your set that be causing this anomaly.

Hi,
Flashing red light in Sony tv indicates that tv got some internal problem and went on protection mode to avoid further damage. Now it needs service/ repair.
Blinking red light also has an error code that has info about possible cause of problem, let me know how many times red light is blinking after 3 seconds ling pause and model number of your tv to provide you helpful info.
Thanks.

Hi,if your tv is between 2-4 yrs and you don't hear any strange noises it might be time to replace the lamp.This will be the lamp you need: XL5200 The Original is made by Philips and it's the best lamp in the market.You can find it on discount-mechant .Good luck and God bless you!

You probly need a new main board.

I took a can of compressed air and blew air into the larger openings. A nice cloud of dust and several puffs of air later, the tv turned on.

In what way is the door broken? melted or cracked or what?

First thought would be the lamp may be about to fail if it has not been replaced in a long time---a warning will be the picture is a bit darker than before and takes longer to get bright than it once did.

There's a good chance you have failing electrolytic capacitors either in the power section or the inverter section or both.
Any caps in these sections that look bulged at the top, or bulged/leaking at the bottom (look for discoloration of the circuit board around the base of the capacitor) need to be replaced.
If you repeatedly turn it off and on, eventually it'll probably stay on, but every time you turn it off, the unit will get harder and harder to start up until one day it just won't.
Sometimes you have to do the opposite to start it up and unplug it for some time and then try again.

If you aren't tech savvy, don't worry, read the rest of this solution and watch the videos.

If you are handy with a soldering iron and can identify the power supply and/or inverter / FM section for the backlights, an inexpensive handful of capacitors will likely fix you right up.
Match the capacitance on the capacitors. Go over voltage if you can, and still have them fit.
IE - it's not a bad idea to replace a 10V cap with a 16V or 25V or even a 50V, but don't replace a 680uF cap with a 500uF or a 1000uF (unless you are SURE it's only doing supply output ripple filtering,
and even then, you should go OVER, not under the uF rating).

Most of the caps that go are 10V 1000uF or 3300uF.

I found some great videos of the procedure (for many Samsungs with the same issue) on youtube.

As you can see, this issue spans plasma TVs, as well as large and small LCD TVs and monitors, amplifiers, computer power supplies and motherboards, and other electronic equipment.
The parts are cheap, and skill required is minimal.
A great parts source is Digi-Key, and you can order the parts online at www.digikey.com
They typically cost under a dollar a piece plus a flat shipping rate.
The parts usually arrive one business day later.
If you watch the third video, you will see that even someone with no soldering experience can perform these repairs as demonstrated by the woman in the video.

Hi,
The Standby/Power light of the TV blinks when there is any internal malfunction in the TV. The self-diagnostic function of the TV will cause the STANDBY light to blink or flash when the television detects an issue. The number of times the STANDBY light flashes corresponds to a specific issue.
Few examples are given below; some of the issues may be resolved without the need for service.
1 blink / 2 blinks / 5 blinks: - This indicates that there may be a power-related problem with your set.
3 blinks: - This indicates that there may be a power-related problem with your set. The set will need to be serviced to allow a technician to determine the specific issue that needs to be repaired. If the power light flashes three times in sequence in a Lamp TV, the lamp cover is not securely attached. Reattach the lamp cover to resolve this issue.
4 blinks: - This indicates that there may be a back light or lamp power problem.
6 blinks: - This indicates that there is some kind of audio problem with your set.
7 blinks: - This indicates that there is a temperature problem with your set. Please check to make sure that the air vents on the sides and back of the set are not blocked or clogged and there is adequate ventilation around the television. We recommend that you check and clean the vents periodically to make sure the set receives adequate air flow. If the problem continues, the set will need to be serviced.
8 blinks: - This indicates that there may be a video-related problem with your set. If the flash sequence is not listed above or the light continues to flash, follow the steps below to perform a power reset:
Try the following steps to check if the issue can be resolved.
Turn off the television.
Unplug the television power cord from the electrical outlet.
Let the television remain without power for 60 seconds.
Plug the power cord back into the electrical outlet.
If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
If the issue continues to occur, service may be required.

Thanks for using Fixya.

sounds like you have bad solder joints,some may have hairline cracks in them from overheating and you may just have to have it serviced.You can open it up and look for bad solder spots and remove the solder with solder wick and resolder it with some good solder.most places use led free solder which doesn't seem to with stand the heat.

Lamp Fan should not cut off and on it should run at all times when TV is Turned on.Lamp Fan is designed to run when set is turned on to Keep Lamp Cool otherwise Lamp will burn up.
Yes Bad optical unit block could also cause set to shut down.But most of them will Play but with Dots,Green yellow tinit or Big blue Spots

Try to mend this cover. It does matter. The tap on the cover activates a switch which is in series with the lamp circuitry.
