Question about JVC RX-1028V Receiver

1 Answer

Stopped working The unit was on and just stopped; it never went to read "overload" on the readout. Power remained to the standby switch but the LCD readout was off. Replaced blown 6.3 amp fuse but dead short on start. Disconnected 3 wire (2 grey; 1 orange) power supply plug from audio power transformer to the "main circuit board"; this brought the LCD panel back; but has dead short when power supplied to main board. Thanks in advance; Steve

    Thanks cowpoker!

    Upon complete visual inspection; searching all components for the obvious burnt up device; I dont see or smell any problems.

    I feel that one or several of the channel amp outputs are bad as you say.

    How to determine the problem if I see no visible damage?

    Thanks again; Steve

    Best source for a DETAILED troubleshooting / service manual? JVC or others suppliers?

    Thanks

    I found two 2 amp fuses blown on the power transformer board. I'm not sure what they protect, any help will be appreciated.

I had a similar problem with a jvc 8040. when I replaced the fuse it became very obvious that the b1560 output on the center channel was blown (smoke and sparks, always a dead giveaway). I haven't fixed the center channel yet but simply unplugged the center channel board and removed it from the unit. Now everything works fine except of course the center channel. Pre outs still operate just fine so a slave amp could be used for center channel power, or you could just go and buy a marantz amp; I did and then I realized that I was lucky that the old jvc quit.

    Steve: I'm not sure what the best source for a troubleshooting guide would be. I know that if you google your 1028 there are websites that appear to offer a service manual for it. I have always had best luck with asking a local electronics guru, unfortunately my guru retired. I tried to take my jvc to another local guy but he turned me away. He said that jvc's weren't made for working on. Therein lies the problem, it's to expensive to get them fixed, but you hate to just toss them.
    I will tell you what I would do, it sounds pretty caveman but most of my stuff does. I would start pulling the channel boards out of it, starting with the front mains. Power unplugged, pull a board, power it up if it doesn't power up replace the board and move to the next one. The problem is that those bottom outputs are a little hard to get to. luckily they're not normally very tight. At least then you will know which channel is bad. Assuming this works and you get the amp to power back up you have the choice of running a slave on the pre-out of that channel (if you have pre-outs), or trying to replace the outputs on that channel. Always replace both outputs, they're only about 3.50 each from acme. Problem is, nothing says this will fix it. I just got done putting both outputs on my center channel last night. Now the center channel works but it is raspy. Probably something to do with the smoke and sparks that I let out of it in the first place. I may try to go in and find something else ( poke at it with a stick ) or I may get an ma-500 to run on the pre-out o the center channel.
    I hope I've been of some assistance or at least entertaining. Or maybe someone who really knows what they are doing will see this posting and tell you to ignore that idiot and then tell you how to solve your problem.

Sony dab fc7 wont power on


Two thing here.
#one the internal fuse has blown unlikely as the standby light is powered.
Two the power supply unit or switch is faulty.

get some one electrical component with the unit unpluged open the case and check any internal fuses have not blown.
Two check capacities on the power board these are large cylindrical shaped objects. These can dry out and or exploded if faulty relatively cheap to replace.
Second check the power switch actual powers the unit again someone with a multi meter and electrical compertent.
It is probably worth replacing either a capacity or switch anything else may prove false economy
I have replaced power board on other units but to be honest unless the unit was very expensive I would buy new

Hi

If no standby light is on (red), maybe a blown fuse that can be replaced with a new one of the same value. If the blown fuse is blackened, some componet is bad inside the power supply.
If the fuse replacement does no result, the problem may be in the power supply (IC power supply switching controller, switching transistor, startup resistor or even an overload in the supply line output) which requires a technician to fix it.

Yes, try to look inside (not in play) when you hit fast forward or rewind--are the reels turning too slow or jerking etc?

It indicates a problem with the transport part of the unit---bad drive idler or even a slipping or bad belt or belts if used.

If you do not get any light on the front panel, it means the 5vdc standby power supply is not working or failed main logic board, you will have to do the power supply inspection first.

Turn off the unit via the standby button on the remote and pick "passive standby". Next time you turn it on the epg will be back. The other option is to turn off the unit via the power switch at the rear of the unit.

Sony KDL40S2010 Bravia LCD TV... turns off / on on it's own


If TV does not remain in standby and turns on itself then power switch on top of it could be defective and power supply board is also suspected. Take off its back cover and unplug top switch connector just to confirm is that cause of On-Off its own. If problem still exist then power supply board has problem and will be replaced. Let me know the results to move forward.

Overload signal


The overload is the same as protect mode. Remove the speaker wires and turn the unit back on. If the message remains, there is a problem internal to the unit in the final stage of the amp.

Please let me know the results of the test above.

Thanks,
Dan
