Hi steff
To answer your question;
If capacitor c973 , 10 mfds/50v was blown off, then you might have the following components gone as well.
D432: 1ss133 switching diode
Q431: DTC124EKA-X surface mount
Note that the transistor is a surface mount component(SMT)
Just requires some time and patience along with a magnifier to replace.
Also you can find those components on the web.
By the way also check the jumper W624 for cold solder joint.
Hope this help Good luck

2003 JVC AV-32FA44 dark screen


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
http://electronicshelponline.blogspot.com/
To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Thick plastic film covering glass screen got deeply scratched while moving


Hi there!
I would simply replace the plastic sheeting. Will certainly be cheaper than replacing a tube. Glass tvs don't normally come with this plastic so leave it off if you can remove it. There is a type of spray on the market for this purpose, just don't know if available in your country. Please note: It is dangerous to use a tv which had been scratched beyond 1.5mm, The glass may become unstable and implode if bumped by accident. Good Luck,JUS004

No picture, No sound


Hi there!
If the set is dead after the popping sound, then it has probably blown a component due to high voltage. Everything inside a tv starts with the power supply. Nothing will work unless the power supply is 100%. I don't know what your rates for repairs are in general, but the price sounds good. The final decision is yours to repair or replace. Good Luck, JUS004

Dark Picture


Hi there!
The knobs you refer to, are those perhaps the knobs on the board or knobs on the flyback transformer? None of these knobs should be turned. They are preset to the factory standard and if a fault occurs the fault should be addressed, not adjustments to pots. I would suggest checking all the caps in the power supply, Line stage and video section. It may also be the video processor(in the area of the tuner section). Check for caps which are rounded at the top. This is common for dark picture. Please note: There is on average about 15000V running through a TV when switched on, please be careful and unplug when changing components or refer to a repair technician. Good Luck, Jus004

JVC AV-32FA44 32" - No Picture, but sound OK


You could have a power supply problem as parts do go bad. Why your set faile is a mystery.. Of course if your not a technician, a TV set is NO place to be experimenting with. It only about a year old you say But get the papers on this set if you can find them and make sure as there is a 12 month warranty on this model. You should contact JVC At 1-800-252-5722 or online at http://www.jvc.com/support/. Good Luck
