    I've got the exact same problem, started 2 days ago. I've not been able to get it to keep the picture though. Turn it on, blue screen for a split second, then black. Again, I have sound, just no picture.
    To the guy that managed to fix his, was it exactly the same fault as described? If so, whereabouts did you find the dry joint?

    I have the exact same problem wit my LTV30C. Turn on the tv but after a while, like 30 secs, the screen goes black. Thers is sound but no picture.
    Sometimes it just work good, but if I turn off and on it goes back to black.

    i have the same problem. But if you look very carefuly, there is image (as if brightness was desactivated). It seems the back lamp is not getting enough power, because it works for a second and then goes black.

    I have no idea how to fix it.

IF you have the manual for that TV, review how to rest the TV to Factory Specifications. Resetting to the original specs. generally cancels out disruptive elements that have invaded the system over time. Other than that, you need to seek the assistance of a serviceman who can analyze the electronics and resolve the matter.

Need tv codes for ltv30c video seven tv

Universal remote codes are determined by the maker of the universal remote, not the maker of the tv, unless they are both made by the same company. Determine the maker of the universal remote and it's model number, then go to the universal remote makers website and look for codes under the name of the tv (or dvd, vcr, etc) that you want to program the universal remote to operate. Programming instructions should be on the universal remote makers site as well. I hope this helps. BobYa

When turned on - green power light comes on then screen momentarily flashes - very quick flashes every second or so.

Are you getting any video on the screen? I would make sure the power cord in the back of the monitor is securely seated. Make sure the video cable from the monitor to your desktop is screwed in tight as well.
Hope that helps

My videoseven LTV30C turns itself off after about 30 minutes sometimes only for 5 minutes - I pull the plug on the wall plug in again and sometimes comes back on and sometimes don't any ideas.... Regards,...

You probably have a component over heating or an intermittant connection. A servicer needs to take the back off and run the set till it fails and try freeze spray to locate the bad component.
