My xbox 360 does not show a picture but has sounds. can It be fixed? If so Where I live In Tacoma Wa.


try using a different tv or av cables. sometimes the plugs on tvs can become loose and that is why you will hear sound but not see a picture.

PT-45LC12 Problem after startup


When the lamp flashes 4 times this is what the error code means IC 2301 pin 11 has detected an LCD error which is caused by an error in the LCD power CBA. which means the lamp voltage has become more than 130 volts or less than 30 volts. Or the lamp current is more than 5 amps, or the lamp is cracked. Its one of thos 3 reasons that will make the lamp indicator blink 4 times. Hope this helps. If you need the service manual for this model you can get one emailed to you from the following link.

No sound on JVC AV-48P575 48 inch rear projection TV


Try going into the menu and find something called, "center channel input." If it is on, the sound will not work. Turn it off, and the sound should be restored.

My Sony tv CRT


If it's between 5-10 secs, that's normal. You will turn the tv on and hear a loud (buzz/hum) that is the picture tube firing up, once it's fired up, it has a few more seconds until your picture comes up fully. That is about 5-10 secs from pushing the power button.

If it's taking longer than that, your picture tube may be going out.

I had a 36XBR250 and it took about 10 secs to fire up and show a picture, and it was 5 1/2 years old.

JVC AV 35750 single horizontal line


Jeremey,
It's ring cracks on the solder joints of the vertical IC... IC421 i mounted to a small heat sink on the board. With the unit off and unplugged remove the board and locate IC421 (LA7832) and closely examine the pins connecting this component to the foil side of the board. You'll notice small rings around the footings that are actually open cracks in the solder, caused by heating and cooling over a period of years. Simply and carefully reflow some solder over these cracked joints, careful not to get the ic too hot in the process, and put it back together.. That should sole the problem...
Another problem we encounter a lot in the vertical deflection circuit of this unit are the two feeder caps C424 (100UF/35V) and C425 (470uf/35v).. If you're already there you might want to go ahead and replace these as well - save taking the back off again if they go bad..

Initially No Picture when Turned on but sound normal and 5 minutes later Picture is all RED and then Picture becomes NORMAL (all normal colors)


theres a high voltage block that all three of the anode leads attach to and sometimes a small crack happens across this block and will not let some or all of the crt's get the high voltage all at once untill it heats up a bit. now if this is not your problem i would make sure that all three crt sockets are attached to there tubes all the way as maybe justy maybe there loose and will only work after ther expand a bit. Now another problem that could cause this problem to occor origially would be that someone left off a crt ground strap and the crt arched and popped and caused the problem with the High voltage block. And no I cant see a tube being bad then comming on at first UNLESS when you say the red comes on is the picture all red with small retrace lines(small white lines)in the screen with no picture except for red???? No video only a red blank screen is what i mean. If thats what its doing then yes Ive seen heater to cathode shorts on a picture tube that would cause this problem but to be sure your really gonna need to have the set looked at.. Good Luck
