Symptom shows tv needs lamp replacement as existing lamp got weak and causing problem.
Did you replaced lamp in last 2-3 years? If not, then its time to replace it to get tv fixed.
Let me know if you have additional question.

There is no problem. Just adjust the picture by moving it up and down with the help of remote control. It is a small button in the center of top row of buttons ( Left of Green switch on/off button). Then adjusting with the up and down cursor buttons.

hi! i have here a couple of codes for your SONY tv, just try them 1037, 1128, 1137, 1178, 1215, 1216, 1218, 1219, 1220, 1221, 1250, 1251, 1316, 1318, 1330, 1347, 1413, hope this helps!!!! goodluck!!!

Could be main board or time control board have problem.

the tv has a bad thermal fuse and with sony is usually a good idea to replace it when replacing the lamp

in examining your question here about going from black to white with no picture at all would thorw the backlight and inverters out of the question. Things to check here:

1. Decoder board
2. LCD panel itself

I have seen where a lcd whent dark because of a back light. but from dark to light and no picture leads me to beleave you have a bad lcd .

I hope this gives you some idea your going to need to have a repair shop fix it ether way or buy a new tv in this case. I do not see this as a common problem in sony bravia lines. Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/edwy_1a56970cf1ea4620

Is your problem of no sound when your using a cable box or going straight to coax? Are you using component wires, hdmi cable or coax?

What you're describing is usually the result of an improperly seated connector. With the power disconnected, open the tv and locate any connectors between the LCD screen and the driver circuit board. Unplug them, and reconnect it assuring it's properly and firmly seated. Be careful when handling these cables as they tend to be quite fragile... take your time.

what does the tv do when you turn it on does the front light blink?or does the tv power up but sound and pic are absent?

if you are not a tech have a tech check your set for possible repairs.if you are a tech you will need a schematic to make repairs on this set.your problem is in your power supply filter or regulator needs to be replace or horizontal output transistor needs to be replaced.good luck.

Depending where you got it It's probably still under warranty.I know Bestbuy usually offers 1 year free.My tv had red lines running through it and they said it was something to do with a climate part that they did not have so I was sent to pick out a new Tv.Good luck

It seems that your unit has some sort of Video side, PSU fault, or a problem to the Video section that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur.
You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done.

Hi there..first off PUT A FAN AS CLOSE TO THE TV AS POSSIBLE...Your units powerboard is overheating..the fan will slow this down big time(once the tv goes all the way out you have a useless tv till it gets repaired!), I have a Poloroid 32" lcd on "life-support" it was doing the same thing when I bought it cheap ( I buy them and fix them), I put a box fan on low behind it and it has not shut off on its own for 3 weeks now....Now to explain how to diagnose and fix this problem............
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!

If this helped you (or not )please rate, thank you!

You are looking at probably a LCD Panel being bad. There is a small chance that a Ballast Board could cause the problem.
I hope this helps,
