Question about JVC AV-32F803 32" TV

1 Answer

Red lines, Red screen, tried previous fixes

This tv has the red lines, red screen, shuts off with blinking led. I replaced the 100mf 160v cap and resoldered the wire wound resistor. The only thing that changed was the tv stays on and can now be turned on and off without unplugging it. Any help would be appreciated. Mark.

I would look for an open resistor in the red drive circuit on the CRT board. Check all the components in the red circuit and replace any which are not within tolerance. The resistor could be from a 1 ohm to 10 ohm depending on the model. If you find no bad parts then check for cracked solder connections on the board and resolder. If this does not work you will need a scope to look at the signal going to the red drive transistor and make sure that it is correct. Anything beyond this will require a repair shop. Remember TV safety. Good luck.

I have an old Grundig tv model t55540-ft. Yhere sees to be a problem with the power button. For the tv to work you must manually hold in the button


Old tvs have old caps and bad grounds. You must take the board out and inspect visually first and then check all caps..I would look for 160volt ti 250volt caps at 1mf to 4.7mf and maybe 10mf caps. Another cap would be the horizontal cap. About 160v to 200v 100mf cap. Replacing these will speed up on time. And remember to resolder all bad grounds especially those on heatsinks. You have to use a leaf blower after pulling the back cover to dust the board before removal.

Sony rear projection screen is red then tv shuts off


Can be 1 of 2 things. 1st the red tube just needs the voltage to it turned down. In the front of TV (you have to remove the lower front half of TV to access it) is a plastic square with 6 knobs. The from left to right top knobs control focus for blue,green red. The bottom knobs control voltage to each tube in same order (so lower right knob for red) turn SLOWLY to left to reduce voltage until excessive red and lines go away. If you over turn left or right set will turn off. If that does not fix it or if lines reappear then option 2 is that red picture tube is failing outright and needs replacement.

3 blinks is the error code for the convergence ICs. You need to replace both STK392-110 convergence ICs. You can get replacement ICs at the following link and they provide installation instructions with pictures.

Blue Screen and TV shuts off


Here's a shortcut to what the blinking codes mean.
http://www.somelifeblog.com/2007/08/sony-tv-led-blinking-codes-what-does-it.html
Strange how some people have 5 blinks. Most with this problem have 8 blinks (like myself)

I still have the blue-flash-then-shutting-off problem.. (8 blinks meaning voltage error) but I did fix the blue lines.. The lines across the screen can be very easily fixed whether they're blue green or red. . No, I mean REALLY easy. Took me longer to get the cover off. Once the front cover is off it takes 10 seconds. This link was also posted recently in one of the posts below as a solution..
http://www.somelifeblog.com/2007/06/sony-projection-tv-red-line-repair.html
(My lines didn't look like the ones in the picture mine were several evenly spaced blue arcs)

After some research I believe the flash/shutting off problem means the CRT is going. I've also read that it might be the D-board and I'm not even sure that that is... But If it is indeed the CRT then I'll let you know it's very difficult to find a replacement blue CRT as this part has been discontinued.. but I did eventually find an alternate to an alternate part (yes that's the 3rd alternate !)) online for $256. Here: http://store.tv-repair-service-salinas.com/8-733-649-35.html

If you're bold enough to attempt that then good luck and please let us know if it worked.
Or another alternative is there's a whole lot of Boxing Day sales goin' on right now.
