TV screens go to snow when I play some karaoke songs on my laptop

[charliebeck]

I work at a place that still uses cd+g discs and a player. There is a modulater that feeds 3 tv's that the machine is hooked to. When I disconnect the RSQ and connect my 2007 HP pavilion entertainment notebook to the modulator some of the songs on my external hard drive will play and some go to snow when they start. The audio will still work. The same songs that go to snow on those screens will play fine on the tv that I use for shows.
Whazzzzzzzzzzz Up????? Thanx for any help.

Sounds like your laptop doesn't have enough power output to the modulator or the wrong type of signal to run 3 TVs. What type of connection do you use for your show TV? You may not need the modulator if the HP output is TV ready (S-Video or RCA plug) Try unplgging 2 of the TVs from the modulator and see if you still get snow. If not then plug a second one in and check. Then the third. Every TV you plug in is going to drop the signal level. Too many TVs and signal level drops too low for broadcast, so they go to snow or blackout depending on the type of TV.

I will take my laptop back again and do that. Im wondering if that modulator is going bad. It looks like it came over on the ark.
But i'll try unpluging a tv or two and see what happens. I have an s video output on my laptop and I have two tv's that work well with it so maybe it isn't my laptop. Anyhow thanx and I'll let ya know what I find out.
