No video, Blown fuse f470, audio works great.

a blown channel or maybe a fuse.more likely the channel.it will have to get repaired by a technition.i had the same problem. one side works well and the other side only just hear a little sound and may be crackly

You may have overloaded your audio output with the external speakers(impedance or short wire problem?)as a result the audio out i.c maybe damaged which in turn may have blown one of several fuses in the power supply.maybe regular GMA type fuse or picofuses,you can try replacing blown fuse but if they blow right back you`ll need the help of a repairman

These unit will mute the video for a number of reasons. F889, F890, F891, F850, F470 one of these fuses is open then fine out what caused the fuse to open. This an older unit so parts may be hard to find. The cost to repair it should not be to bad.

NORMALY SOUND BUT NO PICTURE IS THE LAMP YOU SHOULD CHECK THAT TO SEE IF ITS BLOWN

I had to goto setup and change the setting from s-video to video

ok well both of you have had the same problem i did... to fix the picture problem check the circuit board pd0074 its the yellowish looking one next to the green one which has the ic's on them... ok on the pd0074 board look for fuses f470, f850, and the f851 to see if they are blown the f470 is what turns the tv on and the f850 and f851 are what protect the convergence ic's chances are they are blown.... the sound i don't know how to fix that problem but i would check all the fuses on that board to find out if one more is blown that what i did but the only thing is that i could get the actually fuses for the tv i was told by a tv repairman in my town to just take 2 wires sodder them on to the fuse and take a glass fuse and put electrical tape around them and it worked like a charm... so i hope this helps you.... the most i spent was 30 dollars for the ic's and the fuses all together and i was quoted at 450 to do what i did myself

Solder jumper wires for prevent maintenance.....on signal
board = 008,010,017,048,600.............................T.

Check first to see if n menu speaker are off or then you may have to change audio amp IC. in 7700 location before changing look for blown round black fuse 2A 250V, 1700's

This happened to mine. It was a fuse that cost $3.42 but the service call was $200! If I knew how to do the freaking work I'd be rich!

blown pico fuses and bad stk packs
