Sony KV-27S42 no sound and audio blinks four times

+13 & -13 requires for Vertical Deflection IC and produced by Flyback Transformer, these volts will be produced IF Horizontal deflection circuit works properly. so try to check H-Out Transistor and its necessary volts / signal. Pls also mention correct Model Number to provide you more help.

Black screen

Possible causes
  • Your TV is not receiving or displaying the signal from your DIRECTV® Receiver.
  • Your receiver has correct guide information, but is not processing video correctly.
  • You are viewing a channel where an upcoming sporting or special event is scheduled or has recently ended.

  • Turn TV off and on.
  • Make sure light on front panel of receiver is lit.
  • Press the "TV/DSS" button on the remote control or front panel of the receiver (not all receivers have this option).
  • Reset the receiver by unplugging the power cord for 15 seconds.
  • Check all cable connections between the dish, receiver and TV.

If the picture is black, but the program title and description display in a banner the top of the screen:
  • If the problem is only occurring on a few channels, check the detailed description of the program through the on–screen guide on those channels. Often, we display a blank screen with a banner before and after a high–profile event to alert customers about the event.
  • Reset the receiver by turning off and unplugging the power cord for 15 seconds.
  • Run a signal meter test to check your signal strength (press "menu" and look under "setup" or "installation").

If your signal strength is below 70 (or below 60 on HD receivers) in clear weather on transponders 1 and 2, see our troubleshooting steps for "Searching for satellite signal. Please stand by." You may see zero strength on transponders 4, 12, 18, 20, 26 and 28. This is normal in many areas. Your system manual shows how to run cables and point your dish.

TV suddenly turned off and won't turn on for more than nSec.

Hello kd6aaj, You are on the right track, a vertical line usually means that you lost horizontal deflection which is supplied by the horizontal/High voltage section.The thing that puzzles me is that you did not lose high voltage. Let me explain. In modern TVs the horizontal section uses scan rectification or a process similar to a switching power supply to convert a lower voltage tapped off of the hoizontal/HV section to provide B+ for the rest of the television. So if you lose your Horizontal voltage you lose your B+ also. So you will never see the vertical line because you low voltage power supply if off also. Now I think your Q571 (H-Out), Q572 (H-Drive), Q551 and/or Q552 (H-Control) might be good. However check them anyway. I would also advise you to check your yoke transformer for an open or shorted winding. This would cause you to lose deflection without losing high voltage. You are definatly in the right section just add the deflection section to your scope of troubleshooting.

Sound problem

Is it a hissing sound ? If it is a hissing sound and you can smell ionized air (ozone) then there may be some high voltage leaks (corona discharge) in the High voltage supply coming from the flyback transformer. This happens when there is a path to ground because of dirt dust or spider web, or your surrounding is humid.

Samsung DLP loud vibrating noise

The color wheel is the most common problem in DLPs that cause noise. To determine the cause: Turn the set off. If the noise goes away after about five seconds, then, the problem is the color wheel. If the noise goes away one to two minutes after shut off, then, the problem is a fan. You can find an Authorized Servicer in your area that can tell you the price of repair, by clicking on the Samsung link:

No picture but sound is perfect

Sounds like the video output has a problem. Maybe missing the 200 volts from the High voltage transformer. The vertical circuit may have an issue. Either way it's hard to diagnose without looking at it. If you need a technician contact JVC online at: Good Luck

Loud hum when attempting to turn on my RCA F27628 27"TV

could be that the main b+ filter Capacitor went bad and blew up. Also could have been the horizontal output transistor shorted and the flyback poped. In eather case it would be recommended that you take this set into a repair shop unless your familar with HV circuits in tv sets. Good Luck
