How do I get. Schematic of the controller for Homedics SRM-700?

I have opened the controller and found the parts that were affected by it having been plugged into the wrong power supply but was unable the decipher the value of the capacitor that needs replacing and the on board fuse.

SOURCE: Low voltage power supply fuses blown

Theres two jumper wires around the convergence ic's that supply the +/-32 volts to them.I found a cold solder joint on one of them.This causes the fuses to blow.Their close to the edge where the two boards meet.

most of infocus parts are oem and made by a company in taiwan that no longer makes power supplies, and many of the parts have their stock numbers and not neccesarily a common stock. the power supply, however, is in stock at infocus for about $65.

SOURCE: No power when plugged in. On off button stays dark, nothing works

Everyone has problems with SMPSs; mine started in 1971 when IBM was first using them; they were literally blowing up and throwing molten copper several feet.
Anyhow, if you have the benefit of a capacitance meter with DF function, check the main filter caps all of the smaller caps. The quality and durability of electrolytics is bad and getting worse and once one of these fails anywhere in a feedback path, the supply will not start. HF is hell on electrolytics.
The (ferrite) transformer in a switcher measures very low on the Ohms scale; depending on power handling and service frequency, primary <<100 Ohms, secondary from 0.? - 10 Ohms between taps, because they operate at higher frequencies. The 50 volts from the diode bridge is way too low; you probably have failed 100-200 uFd. electrolytics right close to them although this is fairly rare since they are only working with 120 Hz. From a 120 VAC line, you should have ~ 160-170 DC volts at no load if the caps are still working as they should and you have no notable resistance between the AC and the diodes.
Well-designed switchers are wonderfully efficient and very reliable if the maker didn't cheat on component quality. I've repaired literally thousands as a sideline in a now retired business and after studying them and adding a ceramic cap.or two and better quality electrolytics, they will run for decades. At one time, I had standard repair prices on ~ 70 different models.
My guarantee was 'lifetime' and that was limited only because I retired.

SOURCE: Vizio SV470XVT1A has no backlight

The 24vdc is turn on by the signal from the main logic board, it is not always on, the standby 5vdc is always on. So yes it can be the power supply board is bad, but just to besure we need to find out if it is getting the turn on signal from the main board first.
You can have 24vdc at the inverter board and it will not light up the CCFL until it gets the signal from the main logic board to turn the lamps on (this is the STANDBY condition, the TV is on but the screen in not lit up util it see the video signal).
Send me good clean and clear pictures of the power supply board, budmrtn@aol.com, connectors of the Power supply, bottom side of the board, then I may be able to tell you which pin is a control input pin. Most people will just throwing parts in and hope that they one of the parts will fix the problem. Used Power supply module for this TV is over $100. http://www.google.com/products?rlz=1T4GGIH_enUS282US283&q=delta+DPS-379AP&um=1&ie=UTF-8&ei=USsxTKn3J6TonQfFlJGEBA&sa=X&oi=product_result_group&ct=title&resnum=4&ved=0CCsQrQQwAw

You don't need to replace it, just unsolder the pins and you will find one disconnected, just solder it back and you're done, let me know if i can help more.

The gas ducted heater wont turn off and is pushing cold air through the ducts. What should I do?


If you have checked the thermostat or control to make sure the fan setting is on "auto" and not on "On" or "Continuous" or something similar, then either the thermostat/control is bad and sending the wrong signal to the heater or the heater is not accepting the control because the relay/switch in the heater is stuck in the "on" position.

If you have the schematic for the thermostat/control then you can figure out how to simulate the control signal that would go to the heater and switch between "on" and "off" to see if that affects the operation of the fan. If you can simulate the switching and the fan turns off then the problem is in the thermostat/control. If the fan continues running then to problem is in the heater.

If you have determined the problem is in the heater and you have a schematic for that unit, then you can check the opening and closing of the switch that controls power to the fan to determine which component is not functioning.

Once you have found the malfunctioning unit, replace it or the assembly.

Where can I found the main fuse in a grey Mackie SRM 450 ?


The fuse is actually on the inside. You will need to remove the amplifier from the back of the unit. Remove all the screws and pry open the unit. The fuse will be on the inside.

Mackie srm 350 tweeter is dead cannot find any UK parts servicesa that will provide either a new diaphragm/coil ot even the whole tweeter


Hi,
I found that Stan at Surrey amps was able to supply a tweeter for a srm 350. But you need to let him have the full part number on the tweeter as it seems they have changed the design on the tweeter at one point ( or more ) in the manufacture.

Ilectrical problem


If I only used it for 10 min. and it stopped working? I would quickly throw it back in the box and find a store that sells them and demand a replacement. Or just buy the same exact model and then return the broken one to the store with the same reciept.
