SOURCE: Difference between JVC AV-32F703 and AV-32F704?

If the connector at the back of the tube (several wires) is the same, then you should be able to switch the tube if the "horizontal and vertical deflection connectors are also the same. If you are not a tech, you probably don't want to try this, but if the horizontal and vertical deflection connectors are not the same, then you MIGHT be able to cut the 4 wires and interchange the connectors. These wires come from a whole bunch of copper colored wire that is wrappped around the back of the tube. The wires looks like it is not insulated, but it actually is dipped in some sort of "stain-like" insulation very similar to electromagnetic wire. The 4 wires coming from this stained wire are usually white, black, red, and yellow and are usually a little bit bigger than most of the other tv wiring. Sometimes, that all go to the board on one 4 pin connector, whereas sometimes, there will two connectors with two wires each.
If both sets are torn up, then you have nothing to lose by trying. Be very careful about the big red wire coming from out of the glass part of the tube. If you unplug this wire and then touch the glass part of the tube where it was plugged into, you will get a punch of about 12 to 18 thousand volts. It's very low current and a very brief shock, but it feels like you have been hit with a sledge hammer. I have been "hit" once and I promise you, it will never happen again. Take a screw driver and connect a wire to the screwdriver. Connect the other end of the wire to "ground". You should see a bare ground wire wrapped around the tube. Then stick the screwdriver under the flat rubber insulator where the red wire plugs into the tube and you will hear the spark when it discharges. MAKE SURE THE TV IS TURNED OFF BEFORE YOU DO THIS OR YOU WILL BLOW UP THE WORLD! Good luck. Should be a fun project. Just be careful. Keever

SOURCE: replacement capacitor information

There is a wire jumper labeled W624. You will find a ring crack around one leg. This caused C973 (10mfd50v) to explode. It also takes out D432 (NTE519) and Q431 (NTE2416). It can also take out C432 and if C432 (47mfd25v) is bad it probably also opened R449 (8.2K SMD).

Chances are you should have checked some components related to that IC,namely an electrolytic capacitor.They tend to leak or short.That IC burned for a reason.

Need to identify zena diode D513for JVC model #AV-20F702


Hi: I am asumming you are talking about a zener diode. The only way to identify one is by the electronics symbol on the board in question. Regular diodes symbols have an black arrow symbol with a line across the top of the arrow, on the other hand a zener diode has the same black arrow but the line aross the top of the arrow is staggered or crooked, sort of like the letter Z turned on its side.

TV: bright line across black screen for several hours.


vertical output ic needs to be resoldered. careful leaving that bright line displayed on the screen as this will cause a permanent phosphor burn into the tube. this can not be corrected once burned unless you replace the tube. mch

Replacement capacitor information


it is safe to replace the capacitor with the same ratings.. you can visualize the blown capacitor at its top portion., remove that capacitor and buy same rating written on its body.. voltage and the capacitance.. usually written as 300V and 3300mF.. when returning it, please take note on the diretion,, + and -.

JVC AV-27020 TV Blinking LED, Static Electricity on tube but no sound and image


Sounds like a bad main regulator IC.. Try putting a 100 watt light bulb across the main AC fuse, turn on the set and see if it will stay on longer. If it does, replace the main regulator iC. If it does not, then it could be almost anything in the sweep section of the set, and or in the regulation circuit of the power supply. Look for slightly swollen capacitors in the set. good Luck please do not forget to rate this thread.

No picture or sound


You probably have one or two diodes bad which would have to be unsoldered to replace. Since it is a small TV, it may not be worthwhile to take it to a repair shop -- if you can find a good electronics tech with soldering equipment and a multimeter, have them check out D951 a 12 volt zener diode near the power relay. If good, then I would check out D941 and D942 in the power supply. If all three diodes are bad, the set probably took a power surge or lightening strike and could have other shorted components as well.
