SOURCE: My Sony Bravia turns itself off Stand by red light blinks twice.

If you bought it brand new from a dealer, I would take it back or have them come out and look at it. Less than a month old, it is still under the 1 year MFG warranty or the very best a 30 day one.

SOURCE: my sony bravia tv is flashing red stand by light

Try leaving the TV unpugged for 30 minutes so the TV can reset itself.
If that doesn't work, most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you flashing red light codes, circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.

SOURCE: Red Flashing power light on Sony Bravia 40 in tv

Hi there, your problem is that your powerboard is overheating due to poor capacitors. When you shut it off it cools and lets itself turn back on a few minutes later. Your post has been a while, so you might have lost the unit already. If you place a fan (any type house fan) as close as possible to the back of the tv and turn it on medium (at least) it might keep the tv cool enough to funtion indefinitly....If my advise is to late already then follow this guide I wrote on how to diagnose and repari your tv..Good luck and if this post helped you (or not ) then please rate, thank you!
The caps (capacitors) in the powerboard are going out. This is a very common problem in all class and price ranges of modern lcd and plasma tv's/ monitor's. I don't know if this problem has been like this for awhile or it just started, but either way, if the tv takes an abnormal amount of time to "warm" up then it most likely will go out all the way sometime in the (near) future. If you have a tiny bit of will and knowledge ypou can open the unit and get to the print board. Examine this for "popped" capacitors, they will have a buldging top instead of a flat one. Im gonna try to include a pic of them here, if i can get it this time, I've tried bfore lol. But you can google image a "popped" or "bad" capacitor and you would be able, with ease, to diagnose if you have any of these. Usually only one or two. Radioshack sells capacitors (couple anyway) for $1.59 each. MAKE SURE the replacement is of the SAME voltage or HIGHER, or you will be right back replacing those 2. Every capacitor has a negative pole marked with an (-) on the side of the capacitor(by one of the "legs", always puit the negative (-) "leg" of the new capacitor in the same hole in the printboard as where the previous negative (-) "leg" of the capacitor was ( a capacitor with the negative and positive "legs" put in backwards will result in the new piece "popping" as sson as you turn it on!!) make sure the "uf" rating (for example the most common popped capacitor is the 1000 uf) is the same as the one you are replacing. I needed 1000 uf, 105 c and 26v (volt) ratings for the 1 capacitor I needed to replace to fix my LG 19" lcd panel monitor I found by the trash that the light came on off, but it didn't come on. I replaced that capacitor with ; 1000uf, 85 c and 36 v (volts0...It works fine eventhough the volts and the temperature rating (36v and 85c) was not the same as the (26v(volt) and 105c ) capacitor I removed !! Further, I've replaced capacitors that had the celcius rating of 105 with the only ones Radioshack had, namely 85 c(celsius) they have been working great, but I'm not sure about any effect, nor have I heard or read (yet?) about that making an urgent difference. Many threads that I've read people have done the same, so we should be ok (my stuff has been running good for a while longer then most brand new ones!.............(all these ratings ; 'uf ' and 'c' etc are on the side of the capacitor you are replacing and on the side of the ones you are replacing them with)...For all this all you need is the cheapest solder gun u can find (I bought one for $7.99 at Radioshack), a camera (to take pictures as you go to remember how to reassemble the unit) and, once you have your materials, 20 minutes to replace 2 or 3 capacitors and you are good to go...Most monitors and tvs (lcd/plasma) I've seen you have to lay flat on the ground/bed/blanket etc, to work on (screen side down). Usually there are 2 or 3 screws (or a few more) to remove, then you will have to carefully (its comes off easily most times)insert a flat screwdriver inbetween the casing and gently pry it up as you go around the whole frame. Sometimes you have to remove the little washer arouind the cable input orso, just be gentle and you cant go wrong. Once insidet here will be a box with wires running to the sides etc...unplug, gently, these wires and open the box. Inside you will find 2 or 3 circuitboards, check them all for "popped" capacitors, replace, reassemble and plug it in....Have fun becoming an overnight tv mechanic lol!

Sony Bravia showing 4 red blinks any idea what this means, fault?


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience.

When I turn on my ps3 model cechg01, it blinks the green light a couple times then shuts itself off. No other color lights just the green one, then beeps three times and shuts off.. Can anybody help narrow...


When you plug in your system with the power cable and turn the toggle switch (in the back) do you see the red stand by light?

The red and yellow light comes from 1 bulb and the green and blu light comes from another..

If you have the YLOD and your yellow/red light is out, you will only see the green light.

I am really interested in your problem.

Do this to check your status: If you can do this function below but not any other, chances are, you do have the YLOD. It can be fixed.

Power off the unit using the toggle switch on the back. Hold down the 'eject' button and turn the toggle switch back from off to on. This will run a fan test and should eject your disc. Remember, this will only work on the 20, 40g models. Not the backwards compatible units with the 4 usb port holes and the memory card slots.

Sony 50 inch KDF E50A12U switched itself off!


Does the on/off light flash green and red or just green. Is the light to the left of the on/off light on (this means bulb has definately blown)

Probable problem is that your lamp has blown. This can replaced quite easily, but costs about £100. Search google for xl-2400, there is also a video on youtube showing how to replace bulb.
