Yes , this sounds like the EPROM IC is failing or the crystal that keeps the frequency on the IC needs to be replaced , or even the buttons on the tv could be warped by the heat of the tv( if it is the buttons , then removing the control board from the plastic buttons will stop the random cycle and may make it so you can turn on the tv , but if not then it is the EPROM IC or crystal)
to check and see if the chip is messing up , hold down the menu button on the tv or vol up down and see if it stops cycling thru the video inputs

Projection TV. DVD works. Cable often seems, "untuned". Static & un-fine-tuned sound of channel with black screen. Then, later, it will come on just fine. Sometimes, will go back to untuned status.


I would suspect your cable box first. I would unplug the power cable from your cable box and wait 60 seconds. Plug it back in and try to watch cable tv. I would also make sure the coaxial cable going from the wall to your cable box is connected properly. I would also make sure the cable going from the cable box to the tv is connected properly. Test your tv and see if it works correctly when you watch cable. If this fixes the issue you are good to go.
  • If this makes no difference use a set of new cables if you have them.
  • If this does not work then call your cable company. They may have to replace your cable box.

Scrolling diagonal lines


The cable box signal on the components video have a too high refresh rate frequency, that is the reason for the lines.
Use RCA cables or an alternative connection.
Other solution is changing the display out settings for cable box (from PAL to NTSC etc.)

It looks like either failing convergence IC chips or a couple busted capacitors around them. This will need to be given for servicing.
You could try a hard reset first though: Unplug the TV from the power socket, remove all cabling, wait 5 minutes and replug to wall socket and redo cabling.

However, I think that you could have either convergence problems or a failing power board, for which you will need to get the set serviced.

Hope that helps!

No pic, no sound, but, has all three colors illuminated?


  • 1 Check the power. Don't be embarrassed if your problem is as simple as an unplugged power cord. It's better that you should discover this than pay a repair technician to come out to your house and find out.
  • 2 Isolate the problem. The main troubles that will crop up with a TV set are either no picture, no sound or both.
  • 3 Check the input setting on your remote control. If you have other devices connected to the TV, such as a video game system, those devices must be used with a different input setting than the input you use for watching programs or movies on a DVD or Blu-Ray player. Chances are, the kids were playing a game and forgot to turn the input back the way it was.
  • 4 Press the Input button on your remote control to return to the setting you wish to use. For example, the cable box might be connected to Input 1 and your DVD player might be connected to Input 2. Newer television sets have at least 3 inputs.
  • 5 Check the coaxial connection from your cable or satellite receiver to the television. The cable should be attached securely by twisting the round lock nut clockwise. Also check the power connections for the satellite or cable receiver. If either is unplugged, you won't receive a programming signal on the TV.
  • 6 Make sure the video cable is securely attached to the TV jack if you have a home theater system. The video cable runs from the Video Out jack on your home theater receiver to the Video In jack on the back of your TV.
  • 7 Check your receiver setting. Home theater receivers manage several components, so if you have the receiver set to operate the CD player but you are trying to watch a movie on your Blu-Ray player, you'll need to change the selection to Blu-Ray to watch the movie on your TV.
  • 8 Check the TV speakers to see whether they have been muted by accident. Press the volume button on your remote control or go to the Menu section and scroll down until you reach TV Speakers. Toggle left or right to turn the speakers on or off.
  • 9 Press the speaker button on your receiver to make sure your external home theater speakers are activated. Many home theater systems use external for their superior audio rather than the speakers inside a television
  • pls rte or vote on how helpful it works.

    I have a magnavox dvd recorder, model # ZV420MW8, that I cannot hook up to my comcast cable box, so altho the drawer will open and its showing that its loading on the dvd itself, there is no picture on the...


    Please clarify how you have the dvd connected right now. You should use the video output out of dvd and into the t.v. That dvd don't have rf out. You have to match component or s-video or composite with what your tv has. We can't help because I don't know what inputs your T.V. has. You may have to come out of the cable box with video-outs/audio then into the dvd and then out to the t.v.. Remember, you MUST come OUT with the box and IN to the dvd, then OUT of dvd and IN to the t.v. Always out/in/out/in. You have 3 different formats. Depending on what the t.v. has is the one you will use. Composite is yellow cable...good then s-video used black cable with pins inside....better and Component uses 3 cables red/green/blue....best. Don't forget to also hook-up your audio signal too. This should be enough info for you to get it going. Remember too that you will need to set the dvd on your input the cablebox is on to feed the signal through. You can only record what the cable box is tuned to. That should do it. Good-luck.

    Sony projection tv HELP!!


    Hi,

    Initially, let us try a simple one; flick/snap with your finger nails any and all of the buttons on the front control panel of the TV unit. The ides is to unstuck any of the buttons. They maybe in a pressed position. Incidentally, any sudden change in the weather/temperature? Any rain lately? Condensation, dampness, humidity maybe playing with the rubber pads of the controls or with the electronics inside.

    Alternately, you can try the hard reset; unplug from the mains for an extended period of time, say an hour or more.

    Should none be corrective, pls post back the exact model number.

    Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

    TV will turn on, but not respond


    Good Day, mistymiles;

    Try this before calling a factory authorized service center:

    Press " menu 2 > 4 > 7 > 0 > enter", on remote. After settings have been initialized > press the system reset button on the front, once the LED stops blinking > reprogram settings and tuner channels (if not using box). IF NOT fixed call for service (get estimate before repair) and suspect repair of DM PCB (printed circuit board).

    Good Luck, big IRISH.

    Picture is of poor quality (wavy)


    This may indicate a problem with the RF tuner. When you are using the DVD player is the output of the DVD using the F (RF Coax) Conncetor or is the DVD connect to the TV using the Video/Audio cables (either Composite (Red, White, Yellow) or Component (Red, Green, Blue)). I am do however believe this to be a RF tuner problem. Make sure that the TV is set to channel 3 and the cable box is connected to the TV (set to channel 3). What you could also do is get digital cable and use the video output jack as the input to the TV on one of your aux positions.

    I would first make sure the tunner is on channel 3 when using the regular cable box, or if you are using the TV's cable ready features make sure the tunner is working correctly, this might have to be done by a qualifide TV repair person.

    I hope this helps
    Thank you,

    Can't get second picture in Picture-in-Picture (PiP)


    Watching two separate tv channels at the same time requires two tv channel sources,i.e. a split of some kind. For instance,the cable coming in thru the wall is split-half to tv or vcr/dvd combo and then to tv,the other half to cable box,then out to tv.If what I described fails,then you may have an actual tv failure.PIP video is generally a separate circuit from standard video.An expert tech w/service literature should be able to help. Let me know if you need more assistance.
