JVC TV keeps turning on and off


The on button activates a micro switch (all the front controls) and you would have to unsolder that switch to take it out of circuit----two pins.

If taking it out of circuit allows set to work just use a remote.

Pin cushion falt


Circuit diagrams are available online from 5-20 dollars. I doubt it will do you much good, as you will need to be an expert at tv repair in order to read the diagram, and trace the problem. It sounds to me like a bad capacitor near the horizontal deflection circuits, or a resistor near the pincushion adjustment could have blown. If you really want to learn how to fix your tv, you should visit some learning websites that explain the different areas of a tv circuit board and their functions.

You need to re-solder the circuit board that contains the STK convergence modules. They're on the center circuit board attached to an aluminum heat sink that's about 8" long and 6" tall, about dead center in the circuit board. You may be able to recreate the problem (hour glass effect) by gently moving the heat sink (which the modules are connected to). This gives the hour glass effect on the picture and the advanced convergence screen. This is an indication that the modules pins aren't solidly connected (meaning soldered) properly. Remove the circuit board and clean the old solder off & resolder the modules pins to the circuit board reconnected the board and then retest by again pushing on the heat sink. This is a caused by a minimum effort (a.k.a. minimum cost) solder job, probably done in some 3rd world sweat shop. The "factory" job was good enough for 3-4 years but the heat (and these modules do create a lot of heat) and stress created from repeated use eventually takes it's toll, weakens the pin connections and our problem occurs. take the appropriate cautions working around the high voltage of the set & use a non-conduting piece of wood to push the heat sink when we doing tests. Best of luck, hope ya fix it.

JVC C-21MU1 / High Voltage Problem


Try checking the filter in the 116v line. You may have an intermittent spike coming through the B+ line.(The filter may have decreased in value) Also a small filter in the X-ray circuit could have lost capacitance. There is a low value capacitor (about .047uf @400v) in the collector circuit of the horizontal output transistor that will detune the horizontal circuit causing the HV to go too high. If this cap is intermittent it may be causing your problem. Stargazer Hope this helps

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
