Question about Sony Televison & Video
I have new sony bravia KDL26S55xx. we have problems with the picture - on average twice an hour the picture trembles and it displays mozaics across the screen. I had the aerial checked and was advised that the signal was too strong and had a ''filter'' put on which had no impact on any of the problems. I have since contacted a diff company and was told that the mozaics i get were called pixeling and this occurs only when the signal is weak. Can you pls advise what might be causing these faults and what should I do. thank you
Weather and antenna aim affect digital pictures. If you're using an inside antenna then your position in the room can affect the picture. Sometimes, late at night, the TV station will go to 1/2 power for maintenance and the picture will pixelate. If you are using an inside antenna that is not amplified, get an amplifier, readily available at Walmart or any store that sells TV antennas. Get the antenna as close to a window as possible and high on the wall. Rotate is slowly to get the best picture. If you have an outdoor antenna check for loose connections and hardware that will allow the antenna to move with the wind. During a storm, you can expect the picture to do what it is doing now.

Make sure you have subscribed to a HDTV service with your television provider.
Also, make sure that all of the devices that are connected to your television are HD devices, connected with a HDMI cable, not a coaxial or RCA jack.
HDTVs aren't magical TVs : everything from the source to the television, including your home theater and PVR, if any, must be HD-compatible in order for the picture on your screen to be in high definition.
On BRAVIA screens, I know that, when you select an input, it will briefly show the definition of the source in the corner of the screen. You must make sure it's 1080p. If it's anything other than 1080p, your picture is not in HD.
I remember that my grandparents had a similar problem. It turns out their BRAVIA television was displaying a low quality picture (480i), even though they had subscribed to a HDTV service, just because their satellite receiver was not configured correctly.
So maybe the solution is simply to make sure that each of your devices is configured to display only the highest resolution available (usually 1080p) in order to enjoy the best picture quality. Do not trust "automatic" quality settings, because they tend to select lower quality settings (such as 720p, which is not True HD), when they might be able to display true high definition pictures (1080p).

I also have a 2 yr old Sony KDL32xbr4 that now has multi-colored vertical lines on the screen. I contacted Sony and they say they have "no known issue" of this sort for this model. I find this rather puzzling since I have found numerous postings on the web. They told me to try the factory reset. Whatever. Might as well have said "don't buy a Sony". 2 years! $1300 for a tv and it lasts 2 years! Makes me sick to my stomach.

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! ..Here is a picture of what you are looking for inside the tv...I hope this helped, if it did (or not)please rate, thank you!

Make sure that the TV is on the right setting, either TV for analog pictures, or DTV for digital. Run a complete auto-setup. This will wipe the tuner memory and re-scan. Hopefully this should sort the problem. If you have tested the aerial cable with another TV in place of that one (not just on a cable from the same aerial in another room) and it works but that one won't, then it will be down to a TV fault. If this helps, please rate me!
