Set up menu

I have a sony tv model KV-27FS100 - my problem is that about every 6 months something goes wrong with the chip in the tv and the set up menu keeps flashing on the screen. nothing you do gets rid of it. it will flash off and on by itself and sometimes it stays on the screen for a minute or two and then disappears for a few minutes. then it comes back again.

Check to see if something was spilled on the screen of this set
or using too much cleaning solution.
As it will run down on to the tac switches and create problems with the cpu.
Thanks guy

My tv does not turn on and goes in standby mode


The model listed should display a error code if fails--power light ought to blink a specific sequence of blinks which indicates a general reason for the failure--it will not point to a single part but a general area.

These sets are very well protected and if something is wrong will not allow set to come on.

A lot of these sets are being replaced as they are heavy sets, expensive to repair and rapidly becoming outdated as far as features etc.

Look for the error code but in our shop usually a repair in this model averages over 150 dollars parts and labor.

Sony kv-27v40 standby/timer blinks 5 times


Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

I have a 6 year old(nov 04) Sony KV-30HS420 that turns off all by itself. The screen goes to green and the picture fades to black. The sound will keep playing for a few seconds then the TV will turn itself...


If the screen goes rather bright green it is one of two things:

1. It is possible it is a shorted green gun in the picture tube, there are three of them, red, green and blue guns in neck of the tube.

2. The other possible reason is there is a problem on the small circuit board at the end of the picture tube, this model should use three IC chips, one for each red, green and blue.

Being intermittent makes it hard to tell but ask the shop if they tried the self check this set should have. With the set turned off use the original Sony remote and hit Display, 5, vol down, and power.

If the set has a self check (it should) a box will appear on the screen with up to five items with a zero to the right of each, items will be like AKB, OVP, etc, and if any have something other than a zero to the right it pinpoints what happened.

Sets with this feature record each event where something goes wrong, ANYTHING other than a 0 indicates what failure was detected.

If I was to make a guess there will be a number next to AKB, which is Anti-Kine Bias, this means the picture tube or something on the board at the end of it drew too much current and the set's shut down circuit turned the set off.

I actually fixed one of these where both the blue and red IC chips on that board were bad, needless to say, I replaced all three of them.

Any good shop would know about the self check and even if the set did not shut down in the shop the self check would point to the area where the problem is.

Let me know if you need more help or find a error code.

Comes on and later goes blank


How much later? The Sony sets have a setting in the menu that turnes the TV off if there isnt' any input, Sometimes this feature gets messed up, and the feature has to be turned off, Check that out and see if that takes care of the problem.

Standby light is flashing 10 tims Model KV-HR36


Try unpluging your T.V. for 5hours+, then turn it back on. Worked for It's called a "hard reset" by sony.

Otherwise
Do the following steps
  1. Check the Sony remote for a button labeled "Sleep." This allows you to cycle through the sleep settings and determine how long you want the TV to remain on.
  2. Step 2 Press the "Sleep" button. You'll see a number come up onscreen: usually 15 or 90. When you press it again the number changes, moving up and down in increments of 15. This is the number of minutes the TV will remain on before it goes to sleep. As you cycle through it, you should see a setting with the words "Sleep Off" appear onscreen. If you leave it there, the sleep setting should cancel, allowing you to turn the set off when you like. If you miss it, just keep pushing the "Sleep" button. It will continue to cycle through the options until "Sleep Off" appears once again.
  3. Step 3 Access the timer function to shut off the timer by pressing the "Menu" button, then cycling through the onscreen options until you reach the "Applications" setting. Press it, and then cycle through to the "Clock/Timers" option.
  4. Step 4 Highlight the "Timer 1" setting and press the "+" button. If it's showing a given time, you'll need to deactivate it. Use the up and down arrows and move through the possible options until you come to the "Off" setting. Leave it there; that should shut the timer off.
  5. Step 5 Repeat the process with the "Timer 2" setting, a little further down the "Clock/Timers" menu. Set it to the "Off" position just as you did with the "Timer 1" setting.
  6. Step 6 Press the "Menu" button when you are done to exit the menu and return to the screen. You should be able to view the Sony TV as normal with no danger of it turning off.

good luck

    Menu box keeps appearing on the screen


    There are meny reasons this might be happening. here are a few obvious ones.

    1. The remote is under a cushion and buttons are being pushed.

    2. The Sensor on the set is in the sun and the sun is confusing it.

    3. You neighbor is messing with you

    4. The set has a bad chip/loose connection/etc.
    [you might try something as simple as unplugging it for a minute.]

    5. it's set to 'DEMO' mode.

    Standby mode and can't get tv to work


    This sounds like the set is in protective shutdown. A problem has been detected and the set shut down. Normally when this happens, the standby light will blink a code count. Can you count the blinks and post that number here? That will indicate the circuit in which the problem was detected. Also, please confirm that the model number of the set is: KV-36HS500 as the blink codes are different based upon model.

    Thanks,
