Need value for R541 on JVC TV model AV-27920

[Philip Belleau]

Hi,

Just like the subject says, does anyone either have a schematic or know the
value of R541 (in series with D541, also blown but identifyable) for a JVC
27" TV model AV-27920?

Everything else seems in order.

Any help is appreciated and thanks in advance to those who reply.

Best Regards,

Philip

OK, found what I needed via the web. Thanks.

If it feeds the vertical circuit you could try a 1 ohm or a 2.2 ohm. The
rectifier needs to be a high-speed type.

Yes, this mainly feeds power to vertical also one bit of other
circuit.

You have burned out vertical IC. Change LA7832, 100uF 35V capacitor
with one with 105C spec near that vertical IC, RGP10J diode and this
1.8 ohm resistor. The main reason for this blow up is that capacitor
dry up then vertical IC self-destructs.

The contact between heatsink and vertical IC needs a thin layer of
heatsink grease.
