Open Question

KD-30XS955 won't turn on with remote only manually

The remote control stopped working one day. I have an extra remote control and did not help. The remote batteries have been changed. I can only turn it on and off using the power button on TV set. That is the only button that works in the TV set besides the menu button with the arrow keys in it. The TV is locked in one of the video channels and can't be changed The volume button is not working either. I am only able to connect the VCR and tivo but not able to adjust the volume. I am able to watch live TV and record TV shows with the Tivo unit The TV was working fine with no problems for many years. I was able to make the TV work by unpluging the power but not anymore. Any help will be greatle appreciated Thanks. Pedro

SOURCE: remote control not responding

Perhaps you can try what I do when my KV24FV300 runs through channels and will not stop.  Hard to watch and remote will not work.  Nothing works but on and off from set. 

Sony Says:  Take all batteries out of ALL remotes that you use in any way for that set, VCR, etc.  ALL batteries out.  Turn TV off at set.  Unplug TV.  Wait at least 15 minutes then replace all batteries in ALL remotes.  Plug TV back in and turn TV on from set.

Maybe, just maybe it will work.  If it does not work why not call Sony, they always say that cannot happen but they have a solution for it.

SOURCE: TV will not turn off and TV buttons preform the wrong functions

check D1004 5v zener diode, if defective it can cause you this type of problem, also check D1003 and D1005.
part # 8-719-929-15 from sony.
these diodes are located in HS board, the one where all your front button are located in. by the way the HS board is no longer availableffrom sony

SOURCE: tv doesn't respond to remote controller

This is caused by radio frequency and what i mean by that isyour tv unit is gettng confused with the crystals that control the connection between the tv and remote.The solution to this is to go to wal mart and buy a new universal remote and in the package should be an instruction manual to set the remote to the tv , First find your tv name in the pamplet,second there will show a code of the remote type it in and enjoy.

Hello

Seven blinkd of standby light in Sony TVs denotes a High Voltage Shutdown. Sony TVs have a special circuit built into, called Self Fault Daiagosis. This stage will detect the faulty stage and will give its symptoms in the form of blinks, and are codes to understand the fauty stage inside.
Here in your TV, its Extra High Tension [EHT] voltage at the final anode of the picture tube exeeds its maximum, that is it goes beyond 30KV (30,000VDC], and it is dangerous, that such high voltage will cause X ray radiation from the tube, and the above ciruit sense this condition and gives you a code of seven blinks.

To rectify this fault, you must begin with its main power regulation section. Plug out the TV from AC mains, and open it. Locate the power regulating system. It is easy, that the mains wire goes directly to that section. Which will have a fuse and large filter capacitor, retifier stalk, and an STK Ic screwed onto a heatsink. The STK Ic is the power regulator. It will heat up to more than 70 degree centegrade, and this heat will spread to its surroundings. There are some small capacitors, electrolytic types, are there, has a chance to reduce its actual value due to this heat, and value reduced capacitors will make problems to the actual regulation. you just replace all that capacitors first, keep an eye on its polarity, ie electrolytic capacitors have positve and negative terminals. There will have 5 or so of them, which will not cost too much, and easy to get from any electronic spare part shop.
Check all the soldering points in the power regulator section for any loose or bad solderings. It is best to resolder all the suspected soldering points by applying a little more solder, that loose solderings are very difficult to detect. Resolder all the pins of the above said STK Ic.
Then find out the secondary voltage stage, secondary side of the SMPS transmormer, a small transformer fitted to this section. For 30" TVs, the secondary main voltage will come around 125VDC to 130VDC. There is no adjustment controls for adjusting this voltage, as STK Ics are very accurate in regulation. If it seems to be more than the voltage said above, STK ic may be defective, and should be replaced with an identical type and number.
Before checking the secondary DC voltage said above, just disconnect the supply rail which goes to LOT said above, otherwise the set will shutdown, and there will be no chance to measure this voltage.
Just keep in mind that the power regulator system of your TV has the trouble. You just do these first, and if any more assistance needed, contact me through Fixya. Ok.

7 blinks


Assuming the basics have been signed off, the usual reason that a set will not fire up is a power supply problem. In sets like yours the supply comes from the transistor that supplies the screen with pulses and hence high voltage. In short with a set as old as this I personally would not be bothered getting it repaired. You could probably find someone giving a working set away for free on numerous local selling websites.

Sony KD-30xs955 television won't turn on.


Anthony from Infotech posted the solution at another location:
6 and 7 blink codes 90% of the time are failure of the two control chips on the DZ board IC8002 and IC6501 both are MCZ3001D available from www.mcmelectronics.com
An ability to solder well is required to do this
Alternate solutions are to send the board to www.ptscorp.com and they will replace the chips or replace the board subject to availibility
A technician would charge $350 for this depends where you are

My fd trintron wega (kd-0xs955) will sound as if it is starting of when POWER is pressed then the red stand by blinks a few times and nothing else when it is just plugged into the wall (no cable connected)


The flashing light is "Code" for diagnostics. Count the flashes before it pauses. Some Sony user manuals will have the answer in the troubleshooting section of the manual. If you don't have your manual,

G'Day!

Unfortunately, what you're describing is a repair issue. You won't be able to address the problem with troubleshooting. There is a part inside the TV that needs to be replaced. If you're under warranty, this will cost you nothing. If you're not under warranty the cost will likely be a minimum of $200 parts and labor. However, be warned that the cost could be considerably higher. You can purchase a new 42" TV starting at $598 from walmart.com, so anything more than $250. . . .probably not worth it.


I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please post a comment if you need additional assistance so that I can help you further.
