Dell tv/monitor picture goes blank after 1 second upon power-up

\015 I have a dell tv/monitor combo unit- it is about 5 or 6 years old now. Recently I have experienced an issue where, upon turning on the tv (or monitor), I can see a valid picture for about 1 second before it disappears. I can't get it back. Whenever I power the tv/monitor off/on again, same thing - I get a picture for 1 second and then the screen goes blank. The picture doesn't last long enough for me to try to go into the menu options and try and troubleshoot - though I doubt I would find anything in the menu that would solve this. Does anyone know what might be wrong? For the 1 second where there is a valid picture, it looks fine.Thanks.\015

The synchro transistor has died. The only option is to have it repaired. Just had it happen to mine, can't tell you thye cost yet though as I have a loan monitor while dell fix it. Of course they will find more than 1 item i bet. But a tch who works for samsunhg looked at it and told me it would need to have a new sync transistor. Because its dell he wouldnt touch it.
