SOURCE: InFocus LP540 Power Supply Problem

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: Infocus projector power supply dead

the caps dry out. look for bulging caps. you won't find a schematic for the ps boards. infocus had someone else make them. the problem seems more like a overheating issue. as for the other one with the "just the fans", check the colorwheel.

SOURCE: my alpine five channel amp got fried and on

There is no way to do a bypass without afecting other functions on the AMP. What you can do is try to get the numbers printed on it in order to get a replacement. You may also find it on the diagram but it is a little bit difficult if you do not know how to read it. Next time post the model number for easier reference.

Xtronie x20qa12074802 colour television burns fuses when i power it


that was mean has bad major component either in the power supply board or in the main board.check first shorted bridge type diode and regulator ic and FET transistor in the power supply board if getting shorted.

CHIPLEVEL SERVICE OF MOTHERBOARD


I AM A CHIPLEVEL SERVICE ENGINNER I DO CHIPLEVELSERVICING OF ALL MOTHERBOARD
FOR EXAMPLE THE SMPS FAN JUST INSTALIZING MEANS A DEAD SHORTING POWER SUPPLY SECTION OF MOTHERBOARD IF IT HAPPENS REMOVE THE PROCESSOR CHECK ALL THE POWER CONNECTION LINES FROM THE SMPS CONNECTION WITH ANY OF THE RESPECT OF GROUND IF ANY LINE IS FOUND SHORT CHECK WHICH COMPONENT IS PRIMERLY CONNECTED TO THE LINE AND REPLACE THEM
CONNECT THE PROCESSOR WITH ITS HEATSINK AND CHECK THE SYSTEM WETHER THE SWITCHING IS OK IF NOT CHECK THE POWER IC,RELEATED CHIP RESISTORS AND CAPCITORS,FET,TRACK OPEN

IF THE FET IS DAMAGED IT WILL SHOW INTIALL SWITCHING AT GATES IF IC IS DAMAGED IT WONT SHOW ANY SWITCHING

No power


Check the Mosfets on the P0981 pcb this is the pcb that has the inputs and such.. not the power Supply board. Fets are mounted to the Heatsink under this pcb, but you can get to the pins as they come up thru the pcb . T11, T7, T4, T1 These have 3 terminals Check for shorts or reading the differ from one to the next.. These are Fets so From G to D and G to S shoudl be open. D to S will read some value as there is a Diode across it.. Also If these are bad the Gate Driver IC IC 11 or IC 3 might be the cause. Mine had two shorted FETS and the IC that drove them was bad. IC is IRS20955 Found some tech reports that show this ic was updated to IRS20957 due to issues.. So I updated both mine and replaced all 4 FETS. Good luck .

My tcl tv model tcl 2009 has no power but led is blinking. I replace already the control ic TDA16846 but still not working. what is the possible problem regarding the power supply


A nice little Control IC but when they fail ithey take out a lot of components around the power supply especially the output FET rather catastrophically for the power board.
I would look elsewhere for your fault because if there is a flashing light, the microprocessor has power and that comes from the power supply.
Look for open circuit fuseable links.
Hope that helps.

Pmp3000 problem power supply.ic circuit problem.number series ic circiut..


I have a PMP5000 that I had to resurect. I had to trace out the power supply to repair it.

I can give you hint: First, a small supply runs directely from the line and generates some of the small voltages. While this starts, the main power caps are charged through limiting resistors. The main switcher is brought online and if the power amps acheive balance, then a relay connects the speakers and shorts the limiting resistors.

This is what is in the 5000 and I suspect the 3000 is similar.

In my 5000, there was arcing at one side of the power amps. The board was burned and three power fets fried. Cancer of burned board had to be carved out and traces replaced by hardwiring.
In addition, the limiting resistors were blown open, both main switching transistors were blown and 4 small driver transistors (surface mounted) and several diodes AND a switching regulator chip (surface mounted).all fried/

Hint: When restarting the unit, put a 150 watt light in series with one of side of the power input to limit the current in case you did not get all the dead bodies out.

This is a class "D" amp which drives PCM waves into a filter which is then the audio output. It is much more efficient thaan a linear amp.

you have blown the actual filters that make the sound. a amp is basically a filter with the same filters on both channels on each side of the inside of the amp - channel 1 and channel 2, that pop was in the heat sinks of the amp usually. if you have replaced the fuse in this amp and you get no on light, the internal amp is in need of repair

250/1 powers on but no output


If the amp is not going into protect, the power supply FETs have probably failed. In the corner of the amp near the toriodal transformer, there are 4 FETs against the heatsink. When these fail, the 47 ohm resistors at the base of the transistors often fail. If the resistors are dark, it generally means the FETs have failed. If you disconnect the amp from power and measure the resistance from leg 1 to leg 2 of the power supply FETs, a reading of near 0 ohms indicates the FETs have failed.
