Question about Televison & Video

1 Answer

1989 Sony Trinitron 13" TV: when I press the power button, it buzzes (till I turn it off), and does not turn on until repeated tries minutes to hours apart. Yet if I do not use my TV for days (the longer the better), I can sometimes then turn it on immediately and normally. What should I do?

Hi,

Based on your description a highly probable cold solder joint with the most likely location in the power supply board. Corrective measure would involve re-application of heat using a soldering iron. This would also require familiarity with electronic components and circuitry and of course safe working procedures when working with TV units.

Your best bet maybe to seek the services of a qualified professional, however, if you are considering a DIY (do-it-yourself), pls post back specific model number such KV13XX.

Hope this be of initial help/idea. Pls post back as requested, how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

I have a sony grand wega 65" and i am trying to figure what is wrong it has a light blue X in the middle of the screen and it does not come off


Hello
Your Sony tv is locked I thinks. Try to reset your TV by the flollowing method.

Unplug your TV from AC mains wall socket, and let it be in that state for about 10 minutes or so. Plug it again, and switch on the TV.
While holding down the "Reset"button on the remote control, press "Power" button on the TV. [The TV will turn itsef off, the back on again]. Release the reset button. [NB: You must hold down the Reset button on the remote control until the proess is over.]
OK.

Sony kp-53xbr45 please let me know step by step how to enter convergence service thank you


Hello,

To enter into the convergence service of your sony, follow the steps below;
  1. Press "Menu" on the remote control. Use the up- or down-arrow button to move the cursor to "Setup" and then press "Return."
  2. Use the up or down arrow to move the cursor to "Convergence" and press "Return." This will bring up the convergence-adjustment screen.
  3. Press the up or down arrow to move the cursor to the line you want to adjust (either vertical or horizontal for red and blue) and press "Return."
  4. Press the up or down arrow again to move that line until it converges with the center green line and press "Return."
  5. Repeat to adjust the other lines until all three lines converge and are seen as a white cross.
  6. Press "Menu" to exit the convergence menu and return to the original screen.
You can as well follow these steps;
  1. Press the "Power" button to turn your TV on.
  2. Wait at least 30 minutes before you adjust the convergence in your television. This allows your TV ample time to warm up before you make the adjustment.
  3. Turn your TV to a cable channel or to an antenna channel with a picture that you can see. A music channel with a static shot of music notes isn't the kind of picture you need. Instead, look for a picture like what you would see on a movie, sitcom or drama.
  4. Press the "Flash Focus" button located in the front panel on your TV. You may need to open a hidden compartment on the front of your TV to access this button. The convergence will repair itself automatically after you hit this button. It may take several minutes.
Any of the two processes are detailed steps on how to enter your convergence service.

Take care

If you want to try another code, start over from step 1.
Below is the website for the online manual which will give further instructions.  
http://dishnetwork.com/downloads/pdf/user_guides_and_manuals/remotes/6_3_RemoteManual.pdf

In looking at the manual no codes are given for the Coby brand TV. If the above process does not work, you'll have to call DishNetwork for further assistance. It may be that the remote will not work for your TV.

In order to program my "dish network" remote control , I need the remote control code for "Haier" model HL 15 B-A.


The reprograming of my dish network remote to my Haier tv was accomplished by the following steps: 1. Press the clear tv button and hold down until all 4 buttons are lit. Release the button. 2. Press and release the large red power button. 3. Press the UP arrow button about once a second until the tv turns off. 4. As soon as the tv turns off, press the pound (#) button at the bottom of the remote.

The unit will now be reprogramed.
