Question about Audio Players & Recorders

Open Question

This is a correction to the Carver subwoofer question(s): I inadvertantly mis-identified the resistor in question; it's R107,not R110 ! (Sorry!)

A transistor or resistor burnt beyond recognition i need a wiring diagram to identify the type


You have not mentioned what electronic equipment you are requesting the details.
You will be able to confirm the transistor value from the stage where it has burned which also goes for the resistor. So take tech help than to try with trials to damage the set much further.

Get a separate amp for the 901's and the rest falls into place.

1,2, 5) Place the 901 Active EQ between the pre/main front OUT of the receiver and the TFM-55X. Attach the 901's. Keep track of the jumpers you remove from the receiver. Or replace the jumpers with RCA splitter cables so you still have pre/main connection but can share the output with the TFM.

3) Pinnacle subwoofer (self-powered?) to the subwoofer out of the receiver.

4) Bose (AMS???) 5. As surrounds on the receiver. Place the sub module toward the rear so it mates sonically and directionally with them.

What? No center speaker? I'd get something more robust with bass capabilities, like a pair Bose 301 series 1's because the tweeters face in one direction only.

Except for the amps and the cube stuff that is essentially what I have. 6.1 with full-range speakers everywhere.

I have a 53 inch hitachi ultravision #53UDX10B Its out of focus and when you press the magic focus button it trys then pops up with the # 4 in the corner is this a convergence problem or what ?


Yes, you have a convergence failure. Usually requires replacement of 2 X STK ICs and any burnt resistors associated with the function that is faulty.

Look at the user menu and compare with images on our Convergence Gallery. Try to adjust in the convergence adjust menu. Identify the functions that do not work and make note. When you replace the ICs, pay special attention to the low ohm resistors for the non-working function. They will be located near the colored plug associated with the non-working function. If red vertical will not adjust, check resistors near the red plug.

There are many posts and websites that offer "new and improved Convergence IC substitutes. My advice is to use the original part numbers and replace any burnt resistors with original values. Many ICs purchased on the Internet are very poor quality and do not work. Many users get substitute replacement ICs and never get their TVs working again.

If you have other electronics repair experience, this job may be done with some chance of success. If you have no experience, there are many secondary problems that can and usually do appear. Determining how to fix the secondary faults and how to correctly align the TV is difficult without prior convergence repair experience.

Some of the common problems encountered are:
1. Poor solder techniques, resulting in damaged PC boards or poor solder connections.
2. Poor quality or wrong parts installed and recognizing this problem.
3. Resistors open or burnt. Some resistors are weakened by the initial faulty IC. Replacing with a "good" IC and starting the TV causes the weakened resistors to burn up. IC may be ok but there are one or more open resistors that measured ok when ICs were being replaced.
4. Wrong ICs used, causing resistors to burn up.
5. Resistors that measure normal and become faulty when heated by current flow.
6. Recognizing that convergence circuit is repaired correctly and alignment is needed.
7. Major alignment in service menu required because data is corrupted by multiple tries of magic focus or manual adjustment while faulty circuit conditions exist.
8. Major alignment required because user adjusted centering rings or physically changed mechanical focus adjustment, then mis-adjusted convergence settings trying to correct mechanical alignment faults.
9. User has not connected plugs and connectors correctly and caused secondary damage or mis-alignment trying to correct secondary issue.

Physically replacing the ICs may appear simple but recognizing if a fault still exists or if correct repair is required causes many attempts at repair to fail. Keep it simple. Replace with good quality original part numbers, measure suspect resistors and adjust only what is necessary.

There are only 3 things to fix, IC failure, resistor failure and user induced secondary faults. Data processor and memory is bulletproof.

I have a pair of bose 901 speakers with an onkyo 100 watt amp. the amp is going out i think what is a good replacement?


My $.02: anything strong and clean. I'm partial to Carver amps and have run mine with double M-440 cubes bridged to 400 watts per speaker at one time. Right now I'm pushing them with a single Carver M-100T (100 wpc) and it sounds as good without being dangerous.

RE: arver Sunfire Super Junior subwoofer. In attempting repair, I found Q12 shorted, gate to source(not to drain!), and F1 open. After replacing with exact cmpnts, operation returned to normal, however,...


is that resistor in the line to q12 ? if so it should be in the spec sheet for that device. if you don't have the spec sheet then let me know what q12 part number is.

I don't have any instructions so i don't know how to hook up my speakers and the t.v for surround sound i have a carver avr 100


You should be able to online to the manufacturer of your products and download manuals. However, I will try to help.

Connect the sound output cables from your DVD player including, left/right(white/red) as well as the Coax output/input if your DVD and your Carver each have this feature for enhanced sound on certain DVDs, and connect to the matching DVD inputs on your Carver.

Then, connect your DVD video output either by use of your RGB(RED/GREEN/BLUE cables or an S Video cable to your the matching video inputs on your t.v.

On the back of your Carver, you will find outputs for left and right speakers, connect to the left and right speakers with proper wire. Make sure that the 2 conductor wire is connected with the same side(polarity) on all speakers for the best sound quality.

You will also find rear channel left and right outputs on your amp, connect those to your rear right and left speakers.

Connect the center channel speaker to the center channel speaker output on your amp.

If your Amp has a sub-woofer output and you have a subwoofer, make the connections on that as well.

Test all of the speakers with a feature that many amps have on the menu using your remote, simply called test. if all speakers are connected correctly you will be able to hear each one as they are individually tested by the amp. Hope this helps out.

I have a carver M 1.5 amp rt. channel is out.


Carver designs in general are not easy to repair. I would recommend that you send this unit into a Carver authorized service center. The likely problem is the output transistors, but the driver circuits and predrivers are not simple designs and if there is a problem there, it could effect the outputs. Tracing this will require equipment and schematics that I don't believe are available on the net.

If the resistors were blown, the power amp which is either transistors or an amplifier package has been shorted out. The resistors are very low resistance, and used really as slow blowing fuse. The value is probably a fraction of an ohm (eg. point two ohms)

Basscube 10 dead...need zener and resistor help


The zener diodes are 1N4774, I believe they are one watt. Try 3 watt metal oxide for the resistors. You might as well replace the 6800uF 63 volt main filter capacitors and the 220uF 50 volt capacitors while you're at it. Half the time the heat that cooked your other parts takes them out as well.
