SOURCE: sony Xplod 1000 watt car amp quit working.

Almost all after market amps use 12v at very very low amperage to trigger the amp on. A temporary jumper from the battery plus terminal on the amp AFTER the battery and ground wires are attached should cause the amp to turn on. I would check to see if you have attached your speaker load correctly ESPECIALLY if you are bridging. Most of the blown amps that come into my shop are due to incorrect bridging loads from the speakers. Note that a 4ohm load bridged across both outputs of an amp will deliver a 2ohm load to each of the channels. When you parallel wire two 4ohm speakers together and then attached them to a bridged amp you will be putting a 1 (one) ohm load to each channel of the amp. Please don't make this mistake. It will fry your amp in about a month. Hope this helps. Good luck.

SOURCE: no sound

I had the same exact problem, here is what someone else suggested I do:

I had a problem with no audio and I recently found the fix. When thesub still worked and you turn it on you hear one relay click and thenabout 5 seconds later a second relay clicks and the audio comes on. Theproblem I had lies with that second relay. When you take the case apartthere are 4 circuit boards. The big board with the two big bluecapacitors is the main board. Well next to the two blue capacitors is ablue relay. That relay had a pin that came un-soldered from the circuitboard. I re-soldered that pin and the sub works just like new.

SOURCE: 05 dodge ram with infinity system amp turn?

There is two ways you can do this you can find the turn on wire for the amp and hook it up to the amp turn on wire from the radio (this is the bootleg way and sound might cutout when you turn the radio up)

The best way to go is to go to best buy or your local sound shop and get a bypass harness for a dodge infinity system(go this way so you won't have rny problems)

How to repair a motorola rdu2080d PTT button

If the push to talk button is damaged. You will need to disassemble the radio to get to the circuit board. The PTT is usually surface mount soldered to the board. You will need silver electronics grade solder, a flux pen, a solder sucker or solder wick, a replacement PTT, a soldering iron 25 watts or greater, screwdrivers to match the screws in the casing during disassembly, a table mounted vise to hold the circuit board during repair/ soldering, a very fine grit sand paper to remove any oxidation off the terminals of the PTT for a perfect solder connection, and probably a magnifying glass to inspect the new solder connection with the PTT to the circuit board.

Most of the soldering tools can be purchased at radio shack.

if you have no experience soldering, I recommend going to YouTube and watch the videos posted on DIY soldering to get a good understanding of the whole process from start to finish. There is a huge amount of informational videos on the subject there. I could sit here and try to explain the whole process and why but as the saying goes a picture is worth a thousand words (but a video is worth a million ).

Hope this helps. Have an excellent day.

I have a DHC-MD333 with a faulty rear mounted stereo minijack. Does anyone have a part number, schematic or repair instructions for replacing the headphone jack?

Hi, If your asking for schematics you're a little knowledgeable-which is good. Rarely have I seen " headphone jacks " go bad. Usually the solder joints on the circuit board are a little bit cold soldered ( instead of a nice shining silver color to the connection-a dull frosted appearance) they may even have pulled away from the board a bit. So disassembling the unit ( power off of course ) and checking this ( jewelers loupe or magnifying glass of equivalence recommended) may be all that is required. I hope this was helpful, If so please don't forget to comment back to let us know how we did. Good luck and thanks for asking FixYa, Prodzilla

I replaced the dc jack and had it soldered by a shop and it shows no lights and does not power up. all ribbons are attached what else can it be?

It could be a plethora of things.

I'm going to do a series of question, and info sort of thing pfcjma.

1) When disassembling the laptop;

A) Did you work on table?
B) Used an ESD wrist strap, and connected the alligator clip to a good ground source?
Or alternatively found a proper way to relieve your body of Static electricity?

Fling the motherboard in the trash.

2) When the shop soldered the DC Power Jack, was the Processor, and Ram Memory removed? Everything removed down to the bare motherboard?

Prepare to replace the Processor, and Ram Memory if installed.

(Don't forget to Properly clean the top of the Processor's case, and the bottom of the metal pad on the Fan/Heatsink Assembly, and apply fresh, new Thermal Paste)

3) Did the shop perform a good solder connection, and not a cold solder joint/s, or burn the circuit traces where the jack solders into?

Prepare to have the solder joints re-soldered by a competent tech.
If the circuit traces are burnt, and will not accept a tinning, toss the motherboard.

(No, not my shop, nor am I advertising for them. Just showing you a competent soldering job on the DC Power Jack, for a Toshiba Satellite M35X-S161)

4) Is the replacement DC Power Jack THE correct one, or off of someplace like Ebay?

Not the correct one, and some of the pins didn't line up with the holes in the circuit traces, where a rinky-dink job had to be performed to install the jack?

The answer is obvious.

4) There are fuses on the motherboard. Were these checked?

From the Service Manual;

Power Supply Troubleshooting

> Check Power Supply Status (Procedure 1)

>Are the DC IN and Battery LED's lit?

Replace adapter/battery (Procedure 2)

Check Power Supply connections (Procedure 3)

> Can you turn the computer on?

Are the internal power connections secure?

Perform internal connection check (Procedure 5)

Replace the motherboard

Procedure 5:

The system board may be disconnected or damaged. Disassemble the computer following the steps described in Chapter 4, Replacement Procedures. Check the connection between the AC adapter and the system board. After checking the connection, perform Check 1:

Check 1 Use a multi-meter to make sure that the fuses on the system board are not blown. If a fuse is not blown, go to Check 2. If a fuse is blown, go to Check 3.

You are checking to make sure there is continuity, from the center pin of the DC Power Jack to the motherboard.
You are also checking to make sure there is continuity from the outside shell, ( that is around the center pin), of the DC Power Jack to the motherboard.

OHM's test with a multimeter.
An economical multimeter is around $5 to $12.

If no continuity is found, check the fuses }

Check 2 Make sure that the battery cable is firmly connected to the system board. If it is connected firmly, go to Check 3.

Check 3 The system board may be damaged. Replace it with a new one following the instructions in Chapter 4.

Just wanted to note that there are fuses on the motherboard.

Here is the download page for the free Service Manual,

I've broken the headphone jack input socket on my Sony PCG-7L1M laptop. Can I seperate the key board or split the body to gain access to it from inside. If so can you please tell me how?

No ken1517 you have to completely disassemble the laptop down to the bare motherboard.

The PCG-7L1M Notebook PC is one of the Sony VGN-FS series of Notebook PC's.

Here is the download page for the Service Manual (Free)

Go down to the bottom line that starts with > VGN-A
Scroll across, and click on VGN-FS

This is a PDF file. May take as much as 30 seconds after you click on the above file link, to see the first page. May take additional time to fully download.
Suggest you let the file download all the way before looking through it.

1) Buy and wear an ESD wrist strap, and connect the alligator clip to a good ground source.
(Electro Static Discharge)

I connect to the metal frame of an empty desktop computer case.
You should wear one because your body carries Static electricity. Static WILL fry out (Short Circuit) the hardware components inside a computer. The ESD wrist strap, and connecting to a good ground source, will relieve your body of Static.

The average cost of an ESD wrist strap is $3 to $6.

2) Remove ALL power before you begin.
Remove the AC adapter (Charger) and Battery.

3) Use a multi-compartment container for the various screws you will remove. Mark each compartment for the areas the screws come out of.

There may be as many as 60 screws and 12 different types.
Do Not mix them up.

4) Make notes and drawings as you disassemble. It's nice to have a record to go back to in case you get interrupted, and a Service Manual can only take you so far.

Use a camera, or video cam if available. Use good lighting.

5) Remove the Fan/Assembly and Processor, Ram Memory, and Wireless Module from the motherboard. You want just the bare motherboard in your hand. (You have removed everything else to get to the motherboard)

A Processor is HIGHLY susceptible to Static shock, and so is the Ram Memory. You don't want to be de-soldering/soldering with ANY hardware components on the motherboard.

6) I suggest using .050 Rosin core solder, and a 40 to 50 Watt soldering iron. Keep a damp sponge handy for frequent cleaning of the soldering iron tip, if you don't have a soldering iron stand with a sponge in the base.

I also suggest using Desoldering Braid, (solder wick), instead of a Desoldering Tool. (Solder s-ucker tool)
A lot easier to de-solder with.

Make good clean solder joints. You don't want a cold solder joint, and have to disassemble again.

Do Not linger too long when soldering, or you can burn the area on the motherboard you are soldering, and it won't take solder. (Circuit trace. The copper strip, or area around a hole) {You won't be able to tin the area with solder}

Need advice shoot me a Comment. (Believe upper right of your page)

The headphone jack is a type of TRS connector. (Tip, Ring, Sleeve)
You'll have to look it up on websites that offer TRS connectors, or hit up your computer repair shops in your area.

My ps3 comes on then after one second the power button blinks yellow then goes off and starts blinking red

The G.P.U. and or C.P.U. has lost connections to the main board.
The picture bellow clearly illustrates why .Fixing it yourself with
out the right equipment is a hazardous venture . This is not to
say it can't be done but it's not easy like most guide will falsely
lead you to believe.2a0817d.jpg

lead solder ball . with a solid connection silver solder with a thermal fatigue fracture to the right. All game consoles use silver solder.

My best advice is to simply take it to a reputable repair shop
with a good track record and plan on spending around 125.00 max
with at least a 90 day warranty. This console if considerably more
difficult to disassemble and repair + sony will not touch it if the
seal is broken.

something to think about.

I have a Sony STR-DE345 receiver, it occasionnal cuts out all together, I removed the cover, and there are two round pieces side by side that look like two "c" batteries, well when I wiggle the one on the...

First things first, be careful wiggling components in a unit that is pugged in. Even after the power is turned off and the steroe is unplugged you can still be shocked by a discharging capacitor.

It sounds like you have a broken solder connection. If you have a soldering iron and can access the solder side of the board, you can repair the connection by applying more solder to the board. This will reflow the old solder and add more which should give you a complete connection again. Be sure to check for shorts after you are done. If your solder flows to another component you may end up damaging the receiver completely

How to replace power jack on sony vaio pcg-k33

Short version?

1.Remove the AC adapter if plugged in, remove the battery.

2.Wear an ESD wrist s-trap, and have it connected to a good ground. Work on a table, have a container with multiple compartments for the screws, and mark where each screw came from. There are as many as 65 screws, and 8 different sizes.

3.Completely disassemble the laptop, down to the bare motherboard in your hand. Remove the LCD screen assembly. No Processor, Cooling Tube, Heatsink, Ram Memory modules, CD/DVD drive, Harddrive, Wireless Antenna module, Keyboard, Nada!

4.Buy a replacement DC Power Jack.
Here is an example of one,

5.Use the correct tools.
If you're a really experienced tech, you can use a 30 to 40 Watt soldering iron. No.2 tip. Have a clean damp sponge nearby, to constantly clean the tip.
Make sure the tip is clean and tinned correctly.

Or use a medium priced soldering station.

I advise using soldering wick, (Desoldering Braid), instead of a Desoldering Tool. Works much better.

5.Use the correct soldering procedures.

Linger too long when heating up the solder joint, to remove the DC Power Jack, and you stand the chance of burning the board. (Motherboard)

Also could lift the Circuit Trace right off of the board.
(Circuit Trace may be thought of as a very thin, copper wire on the motherboard. It isn't, but this explanation will do)

Do any of the two errors above, and you can use the motherboard for a Frisbee.

My method for removing the DC Power Jack, is to pull up on one lead at a time. Use constant pressure with my finger, and thumb. (Don't get 'Godzilla' on it. It can break. Everything has it's limits!)

I heat the solder joint for that one lead, and try to pull it up, a little out of the board. Then I move over to another lead, heat it, and pull up slightly on it. Keep moving from lead to lead, until finally they start pulling out.

After the jack is removed, the area needs to be cleaned. I use 90 percent Isopropyl Alcohol, and Q-tips.

This is HIGHLY FLAMMABLE! Keep it away from that hot soldering iron, and use in a Well ventilated area.
Always immediately return the cap to the bottle, and tighten the cap well.
Have fire precautions ready, just in case an accident happens.
Better Safe, Than Sorry!

The area of solder, around the hole in the board for the jack, may need to be buffed off. (Fine sandpaper in a tight roll, or a fingernail file using the fine side)

All areas that will accept solder need to be clean, and tinned.
Tinned, the area is cleaned, a light spot of flux is touched around the rim of the hole, then solder is applied. The hole's rim then has fresh solder around it, and is ready to accept the DC Power Jack lead.

Be sure you have good solder joints! You may not see a cold solder joint, until you put the laptop back together, and the jack doesn't work. Then you get to take it all back apart, look at your solder joints, and go "OH".

This may help you in disassembling,

Thanks for using FixYa. Ten blinks on Sony HDTV means-- Check Transistors Q8014 and Q8013 on D- Board for shorts, leakage, or bad solder connections. If the transistors are bad, then also check R8051 and IC8005, these are also on the "D" board.

Please do rate the solution and revert for further assistance.
