Question about Sony PlayStation Portable (PSP) Console

PSP intermittent powerup

My PSP has an intermittent fault in that it sometimes doesn't power up at switch on. I suspect it might only be a faulty/dry joint on the PCB at the input socket from the charger as it sometimes comes on when I wiggle the power plug. However it mostly fails to power up. I feel I could probably rectify the fault but I don't want to risk damaging anything attempting to open the unit up yo gain access to the PCB. I have removed the small screws that I thought might hold the two halves of the unit together but it still doesn't come apart. Can you give me any guidance on gaining access to the PCB?

Your assistance would be very much appreciated.

Dear Fix Ya Team,

Many thanks for your prompt reply to my PSP query. I thought I would let you know that I have located a PSP service manual in my local library which at first glance looks as though it might contain enough information which should enable me to dismantle my PSP and hopefully locate/rectify the problem. If not I might be in touch with you again.

Once again many thanks.

Zanussi zdt 6053 usually will not run full cycle (on any cycle) but stops with constant error beeps. But it is draining ok and sometimes goes full cycle (not often) Any ideas?


Could be anything!
If you suspect that there is a fault then it will be displayed by blinking LED "END OF CYCLE". As the display of failure in hexadecimal code it can flash up to max. 15 times than short pause and after that repeat fault code. You must to count the number of times the LED "END OF CYCLE" flash up.

Example from user manual: Anti-flood device is activated.
- continuous flashing of the indicator light of the running programme
- 3 intermittent audible signals
- 3 flashes of the END OF CYCLE indicator light
(which means "i30" fault code, the cycle is interrupted and the
drain pump switches on).
Possible causes:
Water leakage from the tub - sump and various connections
(pump, upper spray arm duct etc.); floating sensor blocked
mechanically; microswitch faulty; fill solenoid blocked
mechanically; circuit board faulty (solenoid triac short-circuited);
wiring faulty.
26226179-aipk5px1bmfkdpsmrgevaqwn-3-1.jpg Could be also:
To cancel a washing programme in progress:
- Open the dishwasher's door.
- Press the programme selection/cancel button for about 3 seconds,
until the indicator light of the running programme turns off and the
END OF CYCLE indicator light flashes, indicating that the running
programme has been cancelled and that the machine has
returned to setting mode. It is now possible to select another
washing programme. If a new washing programme will be
selected, check that there is detergent in the detergent dispenser.

NOTE: only during the drying phase, if the dishwasher's door will be opened and remains open for more then 30 seconds, the running programme will be automatically cancelled and the machine will return to setting mode. This will happen, always only during the drying phase, also when the machine is switched off by pressing the
On/Off button and remains switched off for more then 30 seconds.

Panasonic Viera plasma suddenly has no picture or sound, makes clicking sound when you switch on, backlight comes up but no picture or sound .......


The clicking noise confirms that the power trips off as the set tries to switch on. So if you are able to isolate the main power sections, the drivers one by one thus resulting in the power stabilising the suspected component can be isolated.

There is a high possibility that the components over a period of heating and cooling, tend to bring on a problem of dry soldering. So my advice is to check the set for some loose joints that have played on to give you these erratic shut downs or poor performance.

The best way to check for loose connections is to tap lightly when the set is powered on , If there is change while tapping then it seems that there are DRY solder joints. Remove main plug, the covers - with caution of high voltage, check for dry joints, use a good soldering iron to solder all suspected points.

Sometimes the fault occurs when the set warms up, if so you can simulate the heat using a hair dryer on the suspected areas, try with the power supply, distribution, Processor controller, driver controllers on the A/V related sections. Also the use a FREEZE-IT spray can simulate the components to cool and show up the fault.

Based on the above method you must be able to locate the area of fault and solder the sections. Sometimes large IC's- ones with more pins- tend to have drying in some pins and so cause faults related to the IC's protocol. Have a rough idea of looking into the areas to reduce the time of probing.

Check for tips to look into the SMPS unit with some of my tips:

Ge microwave says may not change power level at this time. The micro doesn't heat anything up


Make sure that the program controller is working if not check power - step down supply, the pads are responding- if not faulty pads- or the door switches, if the switch contact are not good then it will not trigger the processor to switch on the waveguides.Since in this case the power level cannot be changed it seems the pads are faulty or the processor has hung up. If so the controller board is a suspect.

If the lights or fan work without any display or action of program being triggered to start then it can be a possible fault on the main board or the processor. Sometimes insect secretion can short the board and display panel and so the processor can work in such an erratic manner. If so clean,solder and reset the board.Now identify the parts by clicking this link: http://www.espares.co.uk/advice/microwave/a/5/141/identifying-microwave-parts.html

If there is no heating please do not switch on unless you have confirmed the fault. It is possible that the Magnetron is faulty, the temperature cut off is faulty or the main capacitor is short. It is also quite possible that insect can get into the oven and create soft spots. When you switch on these will create a short and make the voltage jump and in the long run damage the magnetron.
So Remove cover after disconnecting , check for dirt/moisture in the cabin, if so wipe clean and dry, check the magnetron and area clean and use an jet air to clean off. Check the wave guide covers, if food had deposited
then it must be checked or replaced.

See link: http://www.espares.co.uk/advice/microwave/a/5/1146/how-to-replace-a-microwave-guide-cover.html

Now keeping clear of the microwave, switch on, use a cup of water inside to test.
If you notice any sparks shut off as the magnetron or the main HT capacitor can be faulty. replace with same type.
If there is heating without any issues, you can use the microwave safely

Thank You for using FIXYA.

Yes , the possible fault can be a suspected fault in the sub woofer power amplifier. You will need to remove to check the circuit.
It can be a faulty or dry soldering in the main board., re solder IC.
Also if the IC is faulty it can be erratic, a signal test must prove it right applied to the input.
