Question about JVC AV-48WP30 48" Rear Projection Television

1 Answer

Screen went black

I was watching TV, then the screen flickered with blue, green and red lines, then just went black. I have perfect sound, just no picture. If I turn the set off and wait a few minutes it will operate fine for a minute or two and then go to black again.

Remove the front grey bottom panel of you TV (don't forget the 2 screws behind the front AV cover located just below the power button) then remove the panel behind the grey panel. You should see 2 heat sinks on the front right of your TV, place a fan near your TV and have it blowing on the heat sinks. Now turn on your TV and see if it stays on longer then it has been. If it does, your DC amps might be overheating. If they are, you might be able to fix your problem by adding in a little more heat sink compound between your DC amps and the heat sink itself. You can find the compound at Radio Shack for about $5. let me know if pointing a fan directly on the heat sinks helps.

Why does my tv have one blue, one red and one green line at the top of the screen but no picture?


The CRT inside the TV has gone bad. You can either find the make and model of the CRT and replace it, or get rid of the tv and buy another one.

No picture


Sound like you lost Vertical Deflection.  Youshould not have a line across the screen because this could destroy the threeCRT Red, Green, and Blue (Picture tubes) if left on to long. There is a protection circuit built in to protect your CRT’s.    Check on the PCB-SIGNALboard (Tuner located on this board) transistors Q-206 Collector should be around 1 Volt Base and Emitter 0V. If the voltage atthis point is greater then 5 Volts the Vertical output IC-401 (Mounted on heat sink 7 pin inline IC) is bad, Part # LA7845.  Pin Voltages should be PIN 1= 0V, 2= 34V, 3= 32V, 4= 3V, 5= 3V, 6= 33v, 7= -6V.  Data sheet located at http://pdf1.alldatasheet.com/datasheet-pdf/view/40357/SANYO/LA7845.html

KP51ws500 turns green and shuts itslelf off


There may be several causes but, one is that when any color gun is being over driven, the Sony shuts down the gun to protect it. Try this. Remove the front of the set by removing the two screws from each lower corner. Next remove the black panel held on by 5 or 6 screws. Now you should see a panel with 6 potentiometers on it. Turning the ones on the bottom row CCW reduces the drive. Turn the color down and if all the guns stay lit, SLOWLY turn them up until you get the color balance that you like.
