Question about JVC AV-32750 32" TV

1 Answer

JVC AV-32750 Picture will disappear, but audio okay. If I jar it, it will usually come back on. Also, if I shut it off and let it cool, it will be okay. Seems like something is overheating. TV is 10 years old, so no big deal, but picture is great when on. Texas Ken

Resolder the vertical deflection output IC421. It is located about three inches to the left of the flyback transformer which is the part with the red cable going to the picture tube.

Evenly spaced vertical lines

Check the smoothing capacitor to video output supply voltage, usually derived from any one winding of the LOT. It will come around 10uF350VDC to 47uF 350VDC range. If this capacitor is faulty, or gone less in capacitance with time, this type of fault will occur. Check the green volour output transistor on the video output card, can be located attached to the neck of the picture tube; for any loose soldering or leakage. OK.

JVC model AV-32750..... The close caption feature is toggled on and a large black square is blocking picture. I have no remote to enter the menu settings so using buttons on bottom front. I am unable to...

just look in the section for closed captions----the box is the "text" feature and just needs to be turned off; if you did it without a remote it can be undone the same way.

JVC model AV 278p6 standard television

I'll bet you have vertical output IC with some pins not soldered. This IC ( integrated circuit) is a "chip" that makes the picture fill out from top to bottom. After a period of time heat will cause the pins to crack loose on the circuit board. You need to have a tech check it for you. Stargazer

JVC AV-32730 36" picture problem..

From what you describe, a solder joint has probably cracked loose in a power supply or deflection circuit, which is quite common. Since you do sometimes see a good picture, all of your major components are fine. Repairing cracked solder joints is a very easy procedure and definately worth fixing on a 32 inch TV. The first 2 digits of the model number indicate the size of the TV.
