SOURCE: picture won't come on

1. See the ugly red color bands on the television set? These can also occur in blue and green. We're going to fix these!

2. Front shot of the television. Their are two screw holes on the front of the unit near the edge of each side right next to the speaker grille.

3. Close up shot of the screw hold. It is covered by a plastic cover that has two tabs holding it in. Carefully pry them out with your flat head screwdriver. Do not apply too much pressure or you can break the tabs off. Once the covers are removed, unscrew the two screws with a Philips screwdriver.

4. To remove the cover, pull from the bottom of the front case and rotate towards you. Once you rotate it out, the top will disconnect and come loose. Do not pull it off, as there are cords attached. (see picture) Loosen the cables attached with the twist ties and set the front cover to the left side.

5. With the speaker grille and cover removed, you now need to remove the wood panel to expose the inner electronics on your Sony HD TV. To do this, remove the four Philips head screws from the panel. Then, pulling from the right, rotate the panel off and the electronics will be exposed.

6. This is a picture of the inner electronics of your Sony Rear-Projection High Definition television. The little black box towards the front of the unit is where we will concentrate our time as it is the control for the voltage & convergence adjustment.

7. When focused in on the controls, you want to concentrate on the bottom row for the voltage / ray gun projection adjustment. The colors are labeled below and from left to right are blue, green, and red. Choose the one that needs to be adjusted and turn ever so slightly with your Philips screwdriver to remove the lines. In my case, the red just needed to be turned 1/8 of a rotation to be back in adjustment. Do not turn to quickly or abruptly or you could possibly damage your TV by varying the voltage too quickly.

SOURCE: KV-30XBR910 won't power on, 7 blinks

I have the same set, and same problem. After many hours/days of reading about this issue (which seems to be a popular one for this series and others) I have found a few sites that have detailed info on what can be done. This link is for a different set but the same issue. http://www.agoraquest.com/viewtopic.php?topic=1121&forum=34&start=80&select_page_number=9
This problem seems rampant on many Sony sets. There really should be a class action suite against them for the replacement cost of the parts which can be $400(USD) or more unless you are handy with a soldering iron.
I have a service tech coming by to look at the set soon ($75) so he can tell me what is actuall wrong with it. Once I know if it is the D-board or the usual 3 ICs that die. I will most likely have a friend of mine solder on some sockets to replace the ICs if the happen to die again.
Good luck

Sony Trinitron 30XBR910 Not Turning On


The three blinks code(sony error codes) indicates a problem in the power supply. In your case since you manage to turn it on after a while it may mean that you have weak capacitors or bad solder joints in the power supply.

Sony Trinitron Wega Standby blinks & the TV won't turn on


Those 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://electro-medical.blogspot.com/
http://homenol.blogspot.com/
http://electronicshelponline.blogspot.com/
If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Sony kv-30xbr910 my tv won't turn on and the standby fashes 7 times


Good day.
Your unit has issues with the high voltage section. Particularly the vertical and horizontal sections. Blinking lights indicates that your flyback is not osscilating to distribute the supply to the sections. Please have it checked by a repaiman.
