I would initially try unplugging the TV, allowing it to sit for a few minutes, and replugging it in. If it still will not power on you will need to contact Sony for support or repair. If it is pretty new you may want to check with the store where you purchased it.

Actually try one more thing before concluding that there is something wrong with the sound board or one of the wires in it on this Sony Bravia television. The cable box settings might not be just right for this television. Are you currently set to pcm or bitstream on this cable box? pcm might also be displayed as 2 ch 48 or 96 khz. Play around with the sound settings and see if one or the other will solve this sound issue before writing off the television.

Can you please count the number of blinks in between each pause so that I can tell you what the problem is? Its a self-diagnostic error code that makes the diagnosis a lot easier

Hi Friend,
Check your TV's remote battries. If they are good, then, power off the TV at the main wall socket and unplug the power cord, leave it for 5 minutes. Now, connect back the main power cord, hold the Power On/Standby button on your TV and power then turn ON main switch on the wall. This should resolve your issue.

Thanks,
Shiva

It could be something like an ETC-inverter board, or the power board. I have the same TV with a cracked screen. Are you interested in selling yours?

Sony Bravia... | Answered on Jun 14, 2010


Could be the power board or main board defective, but I suggest you do firmware update first. Go to http://esupport.sony.com/US/perl/swu-list.pl?mdl=KDL42V4100&LOC=3#div_pos_30 download the software.

Hi
Is this a new TV going into an old connection or an old TV going into a new connection? If this is a new connection I would get a hold of Comcast and make sure they have registered the boxes IP address. If this is a new TV then I would go into the menu and select the TV inputs. Go through these until you see an image. If still nothing then the new TV is defective. Good luck

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) then please rate, thank you!3c91ad5.jpg
