Question about Televison & Video

Circuit board fried. anyone have company phone number for parts?

The circuit board was shorted; melting some pathways. it's cheaper to replace then attempt a repair. i already replaced with wire soldered in its place. no go. something else sparked. the motor worked for 1-2 seconds. it worked fine before (2-3 years). if it cost less then $100; it's worth it to me. i bought it off season $150 below retail.($100)worked great till i messed up. also no luck on internet finding anything on parts.

Three suggestions:
Contact http://www.ptscorp.com/television.html. They have a selection of replacement boards or will repair it Fees are usually $50 to $125 and I have had great success with them.
Another would be to try www.shopjimmy.com and lastly do a Google search, if you know the exact part number, to find other sources for the board.

SOURCE: rca digital board?

The problem is a blown fuse on the top side of the board. It is about 2 inches from the tuner. There is a label 7c32 on the board. The part is a 1206 surface mount fuse with a F on it. The F indicates it is .5 amp. The reason they are all failing is because they undersized the fuse. Replace it with a
F1455CT-ND at
http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail?name=F1455CT-ND

This fuse is a little bigger. You can check the data sheet at digikey to get a picture when you are looking for it.

SOURCE: Maxent 26" lcd tv, shorted circuit board

the best and easiest way to track down a short is with a digital multimeter just check for continuity throughout the circuits.If you you cannot get your hands on a multimeter use a compass.It will detect and move left to right when there is a complete circuit and as soon as you hit the short the needle will be dead still. Fix the short and test.It would probably be alot cheaper than trying to track down a part with no certainty of it.Hope this helps

if you are familiar with Micro oven servicing follow these steps

.Repairing a microwave oven is a dangerous task. The high-voltage potential combined with the high-current capability of an operating microwave oven pose a deadly threat to a careless worker
1.Shorted Magnetron tube.
2.Replace Magnetron tube
3.Check Built-in surge protection on printed circuit board has opened. This circuit consists of a fine foil pattern (or filter coil - depending on the model) that acts to fuse the primary side of the low-voltage transformer.
4. Rebuild the surge protection circuit. Replace the varistor
5. Magnetron filament connectors have loosened and, due to resistive heat, the terminal connections have deteriorated and burned off.
6. Repair defective terminals as follows:Either (1) Cut away burned wire, clean the magnetron terminals, and replace the slip-on connectors, or (2) Cut away burned wire and connector(s). Clean terminals to prepare for soldering. Solder filament leads directly to magnetron terminals. Be careful not to apply soldering heat any longer than necessary
7. Check for Weakened fuse clips in the fuse receptacle causing fuse to melt due to resistive heat. Usually indicated by a bead of solder leaching out from either endcap and/or evidence of overheating (or burned spot) at the endcap, fuse clip, or terminal connection

8. Replace amp fuse and receptacle. Generic fuses and fuse holders are available at appliance and electronic part suppliers.
9. Contact service center .. all the best ..thank you

antenna wire connection on the circuit is cut and I do not know where the weld

antenna wire connection on the circuit is cut and I do not know where the weld

you might need to solder it
You attach wires to printed circuit boards (PCB) in a process called soldering. You heat the wire and PCB pad, melting the solder wire and allowing it to flow onto the wire and pad. The solder wire used is typically a lead-tin alloy although in some special cases, silver is used. Soldering a wire to a printed circuit board may be part of making, repairing or modifying the board or connecting it to another device.

Clean the pad on the circuit board where the wire will be attached. Gently rub the eraser on the pad until it is clean and shiny. Strip about 1/4 inch of insulation from the wire. Tin the end of the soldering iron by melting a small amount of solder onto the iron tip. Heat the wire end with the soldering iron for a few seconds and briefly touch the solder wire to the bare wire, just long enough to melt the solder, and let it flow into the stranded wires. This is called tinning the wire. Tinning the wire is not necessary with solid or single strand wire. Insert the wire end through the hole in the circuit board pad from the top or component side of the board. Bend the end of the wire slightly to prevent the wire from falling out while soldering but do not let the wire end touch any other component lead or another pad on the circuit board. Apply the soldering iron tip to the wire end and solder pad at the same for a few seconds until the solder used to tin the wire end melts. Apply just enough new solder to make a dome-shaped puddle on the pad that covers the hole and the wire. Remove the iron from the pad but do not move the board for a minute. Cool the new soldered joint and do not move the board until the solder hardens. Clip the wire end off with the wire cutters. The wire is permanently attached to the printed circuit board.

I have nad tuner 4155,sounds garbled and very little volume


Hi, you might need to replace Some damaged resistor controlling the sound function.
Please if no basic experience ,contact a repairman.

Replacing Damaged Resistors

Disconnect the stereo at the plug and remove the outer case.

Confirm that the resistor is damaged by testing the tolerance with a multimeter. Melt the current solder with an iron and remove the damaged resistor.

Mount the replacement resistor onto the circuit board. Trim any surplus lead material from around it.


"Tin" the tip of the soldering iron by melting a tiny amount of solder directly onto it. Remove any surplus solder and place the tip straight onto the circuit board.

Melt a tiny amount of solder straight onto the joint, using the solder spool. Ensure that the solder does not touch the tip of the iron.


Melt the solder straight onto the area between the resistor lead and the printed circuit board. Leave it to set and ensure that the joint is strong. Reassemble the stereo and test it.

Also Spray the volume control knob with electrical contact cleaner. Twist the knob from low to high to make certain that all the workings are adequately lubricated. This should eliminate any interference that you've experienced when adjusting the volume.

Check the condition of the speaker wires if the stereo is emitting no sound. Ensure that no bare wires are coming in contact with each other. This will result in a dead short. Replace any damaged wires with new ones.


Check the connections of all speaker wires if no damage is detected. Ensure that the wires are securely connected at the back of the stereo and at the speakers' connections. Confirm that the positive and negative connections on the stereo are connected to the corresponding speaker connections.

Good luck..

One thing missing from my WMK300 is a circuit breaker or replaceable fuse. Apparently your wiring became the fuse. Please read and understand my entire Answer before starting.
>>This answer is only for technicians proficient in soldering, with safety training in testing 120 VAC circuits and with an understanding of insulation temperature ratings. Memorize the average torque required to loosen each type of screw and do not exceed that torque when tightening.<<
It is likely that the wires leading to the heating elements are defective. You must open the top and bottom clamshells to inspect the wires inside there. Look for melted insulation, cracked stand-off insulation posts, etc. You will have to repair the obvious problems before the next steps.
>> It is helpful to have a multimeter to test resistance. The heating elements should not have continuity to the metal chassis or ground wire. The resistance of the heating elements should be in a sensible range given the wattage rating of this appliance.<<
If the wire under the damaged insulation is in great condition, you may just repair the insulation. In the base, you may use normal wiring insulation since this area stays cool. I recommend slipping some larger diameter insulation over the wire. (Strip this off a larger diameter wire.) In the hot clamshells, you must use high-temperature insulation like the woven fiberglass sheath used in toasters and ovens.
The two white heavy gauge wires connect to "N" (neutral) and "H2" (heater lead 2). The two black wires connect to "L" (line power) and "H1" (heater lead 1). If only one wire came off you should be able to find the correct solder point to reattach.
This circuit board is not replaceable and there are no components on the circuit board that should be capable of drawing enough current to melt the power wires. However, if you cannot find bad wiring elsewhere, inspect the circuit board for solder droplets, bits of wire, screws, bent components, etc. that may cause shorts. Look for overheated circuit board, traces or components.
>>To remove the circuit board on my WMK300, the temperature control knob is left intact on the control panel. Do not remove it. The circuit board lifts off the shaft of the control knob when it is removed from the chassis. Test the knob motion when mating it to the circuit board.<<
Almost all components except the potentiometer and the 8-pin microprocessor controller "U1" are easy to purchase online.

I have a MTX Thunder 81001 car amp in my repair shop. It has power but no sound, what can i do to repair this amp?


You can open it up and smell for any burned components. Once you identify the burned resistor, transistor, capacitor try to replace it with the same value in RADIO SHACK. Also check for burned out tracers on the circuit board. Thats when the copper etching on the board has literally melted away. You reconnect it by soldering small wires and bridge the connections back together. Need solder and soldering Pen. The soldering gun is too strong and may do more damage to the circuit board if used to long.

I have a Mitsubishi WD-62725 with the ''blinking green light of death.'' I got this T.V. for free so I figured might as well try to repair it myself (and can I just say did Mitsubishi really have to make...


It's definitely the one causing the problem but I suggest you also replace or resolder the 4 capacitors on the DM board to make the job at once. Just make a note on the polarity markings of the capacitors and the board. If there's no indicated polarity markings on the board then nevermind. Here's what you need to do the job:
  1. Soldering iron
  2. Desoldering pump
  3. Soldering lead
Steps:
  1. Heat up the soldering iron
  2. Melt the lead on the board with the soldering iron and use the desoldering pump to remove it and loosen the terminals of the capacitor.
  3. Remove and replace the capacitors one at a time to avoid confusion.
  4. Make sure to make a good solder. A good solder is volcano-shaped.
  5. Cut any excess lead terminals.
  6. Make sure there's no stray leads that might cause short circuit on the board.
  7. Check the terminals of the newly installed capacitors for any short circuit.
Tip:
The board experiences vibrations during the operation of the unit. These vibrations can result to broken solders as the time passes by. Before re-installing the board, check it for any loose or broken solders and resolder as a preventive measure. A magnifier will surely help.
