I suppose you could use general techniques an electrician would use and test the receiver's electrical components one by one to try and isolate one that is not functioning and replace it. Even when receivers are serviced at a repair shop the first thing to do is to connect them to different devices capable of different audio formats with different types of cables ie dolby 5.1, 7.1, true hd and etc.

Tuner of My samsung Tv (EV 500 model)is not working. is IC No. SZM 173ER2 is available now in market ? if so, from where can i get.


Tuners are available as a unit.
Repairing is not possible. Contact SAMSUNG with your TV model no or the part No. indicated on the tuner box.

There are two types of tuner 1. voltage synthesized. 2. Frequency synthesized. Check the type that is used in your TV and buy.

Re: Technics HD51 home stereo system (amp, tuner, CD, and cassette player) - I'm told it needs a pre-amp in order to get any reasonable amount of sound out of lp's on the Linn Sonex LP12 turntable. At the...


The Amplifier must have a high impedance input for the turntable to be connected. Now most of the present day amplifiers do not have this input but only the regular aux input which is designed for a larger signal . But the turntable outputs is quite low and so it requires an amplification of high order. What you can do if you need to play the turntable is to have first a preamplifier with a high impedance which is available even inkit form and can be fitted on to your system. The preamp output can be shared into the input of the source selector maybe with a switch and you willl be able to fix two RCA sockets to accept the input of the phono. This will work fine provided the shielding is done well to avoid the high feedbacck to oascillate and cause noise, the premap must be housed in a shielded cabin. On the other hand you may have to buy a universal amplifier so that the phono input is present. Definetely nothing better than a designed input. So think and decide. hope I could help; Good day

I am trying to locate a replacement SVI 3023 IC, as used in Technics SA-R230L Tuner/Amplifier. Thanks, Dave.


The SVI3203 is no longer available. If you can find an SVI3205 (it too is no longer available), you can substitute. Where are you located?

I have a Siriusconnect Home Tuner and an XM Ready Receiver. Will they work together? What do I need to make the connection from the 8-pin mini DIN on the Tuner to the XM connector on my Denon AVR-587?


Not gonna work, sorry to say. You need the little two-piece "XM Ready" tuner unit (with antenna) to plug into your XM Ready receiver. Sell the Sirius Connect Home Tuner and buy the XM unit. XM unit still available at some Best Buy stores.

My amp is working fine but turns off when i insert a CD


Hello pumpin_up_da,

The most likely cause for the problem you describe is that the remote turn-on lead to the amp is functional only when the head unit is operating in tuner mode. This could be caused by using a power antenna lead instead of a remote lead. Some head units have both, some only one or the other. Check the wire going to the amp remote terminal with a voltmeter. If it shows 12V when the radio is operated in tuner mode but 0V when you switch to CD, then check the wiring. If this is the cause, and your head unit has a dedicated amp turn-on lead, then connect it to the amp terminal. Most head units that have both power antenna and remote leads code them "Blue" and "Blue/White". If your head unit does not have an amp turn-on lead, you need to wire it to a 12V switched source, usually the "red" wire on most aftermarket receivers. You can then put a SPST toggle switch (available at Radio Shack or most auto parts stores) in line with the wire and turn it on and off as desired.

If the correct wire from your head unit is currently connected, then the receiver is defective and needs repair or replacement. Or, if everything else still functions normally, and really don't want to bother with repair or replacement, you can still use the 12V switched source as described above.

Hope this helps.

Motorola Dual Tuner PVR - DCT 6412-III --- HELP


I was just reading another blog on this problem and it seems you must clear any recording setup you have for the program the go to the settings and in the history file delete all listings of it. This can take a while as you must delete them one at a time. Then you can reset the series or single recordings. Seems to work for some people. I am having the same problem and programs are disapearing one at a time. Good Luck

Motorola Dual Tuner PVR - DCT 6412-III --- HELP


Hi.
The information provided shows that tuner 2 isn't working at all on at least the selected channel. This could be a problem on just some channels with this tuner or possibly all channels. You can verify this by hitting the "SWAP" button on the remote to switch tuners while viewing a live program on a problem channel. If you choose the same channel for each tuner, I expect you will see program on one and "one moment please" or freezing or pixelation on the other. The confusion about recording comes about because of how the DCT6412 chooses which tuner to use for recording versus viewing. If you activate record on a channel you are watching, it will use that tuner. If you see it, it will record. For future or series recordings though it will automatically choose to use the alternate tuner so that it won't have to change your channel selection. Since there is no input signal detected on the other tuner, it will actually record but there will be nothing to see on play back. What causes this? It is probably that tuner 2 has failed. There is a slim chance that your cable signal coming in is either too strong or too weak but this is unlikely since the DCT6412 splits and then amplifies the cable input signal before distributing essentially equal signals to both tuners (the plug on coax adapter on the back feeds the cable signal to an AGC amplifier within the DCT6412 and then splits and distributes that output to both tuner inputs). You could check the OOB AGC level as described here http://www.cable-help.com/ but I think your problem is more likely that tuner 2 has gone bad. JM Belleville Ontario

Motorola Dual Tuner PVR 6412-III ( HD )


If you cannot get it repaired, note that it has a 120GB disk-drive -- very small when compared to the latest model (500GB), and note that the disk-drive probably is approaching 10 years old -- doomed to "fail" soon. Replace it, and add an external-SATA "Expander" to add another 1000GB of storage of recordings.

I have a Harman Kardon 700 Series amp/pre-amp/tuner system that I want to get repaired ( an HK 770 Twin Torroidal Ultra Wideband DC Amplifier, a matching HK 725 Pre-Amplifier, and a matching HK 710 Tuner)...


This will take a little homework on your part, but parts for this might be available. I don't kow your model well enough to know whether or not the power switch is generically available. Any possibility you can post a picture? Manufacturers are only required to maintain spare parts for 5-7 years after they stop selling that model. If the part is generic enough, other distributors will carry replacements. If all you need is the power switch, you stand a good chance that a replacemetn is available.
Keep me posted,

Wiring my tuner-DEH-1800 to Amp GM-5300-T into my 4 speaker system.


Hi,

In most head units as in your case the Pioneer DEH-1800, there would be 2 RCA female jacks at the rear of the unit. These are your OUTPUTs.

While in most amps including your GM-5300-T, there would similar RCA jacks which would be your INPUTs.

You need to connect the output to the input using an audio cable terminated at both ends with RCA plugs. Further you need to connect the remote trigger on from the head unit to the remote/external amp to switch it on.

A more comprehensive connection diagram is available at page 6 of the GM-5300T Manual which may be downloaded from here.

Hope this be of help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.
