The light flickers because the power source has detected a failure and has shut itself down. Nothing more you can do, the tv must be repaired by a pro.

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 tobuy and 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.4_3_2012_1_28_26_pm.jpg look at power board for caps puffed up like these

Television does not turn on, no stand by light


Hi you will probably find it very difficult to get the parts for that make of telly did the repair shop look inside the telly or did they just turn you away when they see what make it was.
The problem your having could be one of a couple of things.
The first thing to check would be the internal fuse only check this if you have nothing at all coming on not even the standby light.
If the standby lights on then the fault would be in the high voltage part of the board.
I have looked everywhere for the schematics for your telly and have been unable to locate one on line.
The place to start looking for the problem if you are able to look yourself but only do this if you ahev some experiance in this kind of thing else you could damage the telly further.
If the fuse is blown you could change this first but if it is blown you need to find out what has caused it to blow.
You will probably find that it could be the power relay transformer that the power lead goes into inside the telly this is the most likely problem because if this was fine then you would at least have the standby light on as you dont then it probably is this.
It could even be a resistor or transistor around this part that has gone these will also need testing but without schematics you would be guessing so that would be the first thing to do is locate schematics i have looked and not found any yet but will keep looking for you will let you know.
As for parts if you can get the part number off the part thats gone then you might be able to source one using search engine but you will need to get the part number, this would be on schematics also.
If you arenot able to repair this yourself but can get the part number and source the parts yourself then repair shop should fit them for you.
Ill have another look now for schematics and also see if i can source any parts for your make and model ill get back to you soon ok

Turn telly on, no sound, no picture, its a sony trinitron tv type kv-28fx20u


Hi,
If standby light on tv is not blinking that means tv needs power up command either by remote or power button on tv itself.
Press Program +/- button on tv front to turn On tv.
Thanks.

Swapped ps3 (1 day old) from hdmi connection on telly in lounge to telly in another room on scart and no picture!! Disc is 'whirring' nicely, lights are on but nothing on av channel??? Any suggestions?...


You need to reset the display back to standard definition. Please do the following steps:

Step 1. Turn the PS3 off into standby mode ( red light on )

Step 2. Press and hold the power button. It will beep when you first press it then beep again 5 seconds later. Release the power button when you hear this second beep.

Step 3. Wait for the PS3 to start

Hope this helps

Unit intermittently makes the TV flicker the sound and picture.


I would be checking and trying new leads from the antenna part of your telly to where they go into the wall , we had a problem with a new tv that used to turn itself off and on we got the tv replaced with another new one and it still did it . it turned out to be a faulty cable from the pay tv box on top of the telly as they emit FM waves just like the radio and it was sending signals to the remote on the tv to turn it off
