Picture on tv started waving in & out

 

normally this problem is due to main filter capacitor failure in tv which is located in power supply.it becomes dry after few years

 

you can also check for normal voltage at input to your home.

hope this will help

good luck.

Tv went Black and wont come on now?

Sounds like you were having a power failure in the community,, we call it a brown out. just turn it off and unplug it,, I'm not sure if this is what the problem is.. I had this to happen years ago on a magnvox console.. I will check and see what I can find out for your model tv..

JVC projection screen with blowen fuse

You have to check the reason , why the fuse blew. It is something else that made the first fuse blow. The fuse has nothing to do with picture after the TV starts up.

Double Vision ...w/waves on top/bottom too much green.

1024x768 Normal 0 Convergence


When A REAR PROJECTION TV has coloured outlines or a 3D image the Convergence Circuits most likely need attention.

Replacing the output amplifiers (located within the Convergence IC's) allows the pictures to line up correctly, and no more color outlines.

This is the most common fault in all makes of rear projection TVs.

Some models of TV require major disassembly and considerable shop/manufacturer's support to repair because of their design that causes other power supply or vertical deflection problems. The poorly designed products require a "bench" repair that can typically cost from $350 t0 $700.

Some TVs are designed for on-site repair and have more reliable circuit design that does not usually cause damage to other parts of the TV when convergence chips fail. The ones that usually allow reliable on-site repair are JVC, Samsung and Hitachi.

It is normal to have some resistors in the circuit burn up or increase in value from the heat (from 2.2 ohms to 5 or 10 ohms). These resistors must be replaced with the right value or the chip may fail again.

This is not a simple repair like changing batteries or a fuse. Reading through the other posts shows many that try and end up with bigger problems.

Your JVC uses STK 392-110 IC's. Misinformed people replace the IC's with other "new and improved" IC's, like STK 392-150. These are devices with different characteristics and require different value resistors in the circuit. Replacing with the STK 392-150 will cause overheating of the resistors and a damaged IC.

If you are in Calgary, I can help. If not, get someone that has experience working on your JVC. My website is below with some costs and explanation.

JVC TV TROUBLE

If you guys do not have hand soldering skills or know how to use a multimeter, I would suggest to replace the whole assembly.
If you know how to solder you can just replace 2 ICs that are mounted on the big black heatsinks and possibly 1 or more resistors.
Click here to find the entire assembly for your TV.
The link provided is for parts for the AV-56WP74 model ONLY. For the 65 inches; you should contact the vendor and provide the correct model number.
Good Luck.

No Picture / No Sound

What was happening before can put you close to what when out. If you had color problems or sound, or even picture going small. these are symptoms that causes the set to go out. If color look in the convergence area and look for blown fuses and bad resistors. If just went out the look at horizontal output transistor.
