Question about Mitsubishi WS-65513 65" Rear Projection HDTV

2 Answers

Wavy picture Picture is very wavy when I turn the t.v. on for the first 20 minutes or so, then clears up. Not sure if it is a problem with my Directv or my television set. Mitsubishi 65513 picture is wavy from all sources first 3 or 4 minutes and then is OK.

It is your TV problem and there would be few capacitors in power supply and deflection section that are weak and should be replaced for correct picture.

    If you are comfortable with electronics repair, have electronics knowledge, soldering tools then check weak and leaky capacitors in TV and replace them. This will resolve TV problem.

    Check electrolytic capacitors in Power Supply and Horizontal Deflection area on main board.
    you will notice few caps plastic jacket (cover) is bit shrinked, replace them with same value.

It looks like you have a convergence problem here, probably a defective convergence IC.

    Do the steps below:

    To start unplug TV from power for ten minutes.


    Try unplugging the video cable, test the TV with a different receiver box and also with a different cable if possible, this will tell you if problem is TV.

    If the problem is the TV, then if you have wavy picture, with colors blurred and not matching, or distorted picture at the screen side, then that means that one of the convergence ICs had blown.

    Replacing the convergence ICs is a delicate job, and must be done by a technician.

    Link below shows the replacement procedure on a different rear projection, procedure is very similar on your TV:

Could you please tell me how to reset my tv? I have a blue screen
What should I do if my TV screen turned black, blue, or gray? print.png Print try this.

Proceed with the troubleshooting steps below only if you're seeing:
  • Black, blue, or gray screen
  • "No Signal" message without the DIRECTV logo
Note: If your TV screen appears "frozen" or you're seeing wavy lines or overlapping images, try this.
Solution 1: Check that your TV is set on the right input
[img border="0" alt="Image" src="https://cdns.directv.com/cms2/global/icons/sm_cl_blu__number1_icon.png">Turn your TV and receiver off and back on.
[img border="0" alt="Image" src="https://cdns.directv.com/cms2/global/icons/sm_cl_blu__number2_icon.png">Using your DIRECTV remote control, press the TV Input button to cycle through TV inputs (Component, HDMI, etc) until you see a picture. If nothing happens when you press the button, try programming your DIRECTV remote to control your TV Input and try again.

Note: You can also try changing the TV Input using your TV remote.
[img border="0" alt="Image" src="http://www.directv.com/cms2/global/icons/sm_cl_blu__number3_icon.png">If you're still having issues, check the cable used to connect your receiver to your TV.
Still not seeing a clear picture?
Continue to Solution 2.

Solution 2: Reset Your Receiver
[img border="0" alt="Image" src="https://cdns.directv.com/cms2/global/icons/sm_cl_blu__number1_icon.png">On some DIRECTV receivers there is a red reset button located inside the access card door on the front panel. Press it, then wait for your receiver to reboot.

Note: If you cannot locate the red reset button or your receiver does not have one, unplug the receiver's power cord from the electrical outlet, wait 15 seconds, and plug it back in. Then press the Power button on the front panel of your receiver and wait for your receiver to reboot.

Hello,

The problem with the television is the lamp. It is faulty that is why the screen turns wavy in minutes.

The solution to that is to replace the light and your television will be in good condition once again.

Take care

It is capacitors in your TV set. If you fix it before the set goes out, you will save about a grand. Contact me @ techman32k@yahoo.com

You have problems with your power supply filters. I'd suggest you to change the mainfilter, that is the capacitor just after the ac rectifier and the b+ filter, that is the capacitor at the output of the smps, and then vertical filter and video filter. These are all capacitors with higher microfarad ratings, if you are not much comfortable, it's better to get some help from someone who is familiar with these. Pay attention not to reverse the polarity when changing the capacitors.

Wavy Screen on Startup
I gather from your post that wavy can mean two possible things as the TV comes on, you see the picture flow like ocean waves? In this case you may have 60Hz hum modulating with the picture, this is actually unlikely these days, but I have heard it happens sometimes. The other thing it could be is light horizontal tearing. This happens when the horizontal frequency is too high or too low. You are not going to like my solution because I feel that for problems like this the set must be analyzed not just subjected to "shotgun troubleshooting", so here I go, Take the TV to a repair shop.

this is caused by a bad convergence module, and there are probably some dried out electrolytic caps in the circuit as well. i have one in the shop right now that came in with the same problem. if you have it serviced, make sure they replace all of the convergence modules (there are usually 2, but sometimes 3 of them), because if one went bad the other(s) is likely to go out soon as well.

Blinking light, but screen comes back Ok, I have the same model WS-65511 and what's happening is slightly different. The audio is on, but the screen is black...the green light is flashing for a minute. Then out. I press the power button and the screen comes back on for about 2 minutes. Sometimes I have to press reset because the power button will not turn back on. Twice it stayed on from 5-10 minutes, but mostly 2 min. I've done this exercise 50 times! I've done the reset, but not but NOT by unplugging the power cord. I've read about the capacitor issue. Is this the same problem or something completely different? Thanks!!!!
