DSP-SLEEP-PIC. To select adjustment menu use CH+/CH- buttons. To enter the adjustment menus, use VOL+/VOL-
MENU
Before doing adjustments, list down the adjustment items and their corresponding data so you can return the data to previous settings in case the new settings result to more problems.
Defrost regularly or when thick frost accumulates in the freezer compartment. Frequent opening of freezer or cooling compartment doors can accelerate accumulation of frost. Thick frost can turn off thermostat and prevents running of compressor motor. This creates a situation of thick frost on freezer but cooling compartment is not cooling enough.
Minimize frequent opening of refrigerator doors.Frequent opening of ref doors makes cold escape from compartments and lets in the hot air. This forces the motor compressor to work harder and increases power consumption.
Install the Refrigerator unit in a place with good air circulation and away from direct sunlight for better cooling efficiency. Ideally, the back of the Refrigerator should be at least 10 cm. away from the wall and its top must have a clearance of at least 30cm. from the ceiling.
Clean Refrigerator regularly to minimize accumulation of odors.
Use plastic ice scraper to remove stuck items or ice from freezer. Do not use knife or ice pick when removing items stuck in freezer as there is high risk of puncturing the tubing system of the refrigerator which causes leakage of refrigerant and results to a no cooling problem.
Check that refrigerator door gasket is still pliant and magnetized allowing it to cling to the the cabinet sides to seal in the cold. Leaky gasket reults to cooling inefficiency which wastes electric power.
Do not overload washing machine. Put in the amount of laundry equal to or below the rated load capacity to prolong motor life and minimize stress on mechanical parts.
Take care not to drench the timer switches with water as this can cause electric sparks. Electrical sparking can burn switch contacts, gears and springs.
Make visual checks for water leaks. When the water level inside the laundry tub is decreasing even when the wash selector is not in drain position means that there is a leak in the tub or the drain plug. Leaks must be fixed to avoid waste of water.
Remove all coins, keys and other items from the pockets of pants and clothes before putting them in to the washing machine. Coins and other small objects tend to get lodged inside the drain tube of the machine and block the water exit to the drain hose.
If your washing machine is an automatic-type using a push-button electronic control panel, unplug the unit from the AC outlet every time there is a thunderstorm. Lightning strikes on electrical lines can cause power surges that can damage parts on the electronic panel.
Install washing machine on level and stable ground so it won't "walk" when tub is spinning.
This TV that came in for repair was found to have a Horizontal Output Transistor D1878 (on board location Q522) with a short between the collector to emitter. When the defective transistor was pulled out of circuit there was still a short measured from the B+ line to ground. The deflection yoke was unplugged from the TV's main board but still the short was present.
Tracing back towards the power supply it was found out that a shorted RU3A diode on board location D921 is shorting the B+ line to ground.
Replacing the transistor D1878 and diode RU3A restored power and normal operation to the set.
A Philips 43PP7445/69 Projection TV came in for repair with complaints of black horizontal lines on the picture. At first it seems that an interference in the video circuits is causing the problem. But when I entered the convergence alignment mode the problem showed itself as horizontal jittering which can be seen in the vertical lines of the convergence alignment cross.
By swapping boards the problem was isolated to the ACS Panel which controls the convergence alignments.
A Philips Mini-Component with 3-VCD Rotary Changer and tape deck has symptoms of tape automatically stopping within 3 seconds in the rewind and fast forward mode. Tape playback function, though, is normal.
I have replaced the rubber belts on both tape decks as part of the routine service procedures but tape deck still automatically stops and can't finish rewind or fast forward action.
I noticed the optical encoder discs located behind the tape deck to be dusty and tarnished so I cleaned it using cotton swab.
Cleaning the optical disc encoder finally solved the problem of tape stopping on rewind and fast forward mode.
It is the fashion these days to show concern with the state of the environment. Rampant use of the Earth's resources have wreaked havoc on the environment. Pollution has become a by-product of manufacturing activities.
To save the environment one of the solutions being implemented is recycling of materials from electronic waste.
The activity of recycling is a process which involves four steps:
Collection of discarded products
Processing: Extracting the materials from the e-waste and sorting the materials into homogeneous types.
Manufacturing: Using the extracted materials in the production of new products.
Purchase: Manufacturers market the products and the consumers purchase the products made from recycled materials.
As we can see manufacturing is the third step in the recycling process. But the bottom line is recycling has been made an adjunct to the manufacturing system and encourages the throw-away attitude among the consumers towards electronic products. The sooner the consumers allow their old appliances to be taken to the recycling plants the easier will it be for them to decide to buy new appliances.
And so we suspect behind all these a strategy of planned obsolescence which may be seen as artificial and intended to shorten the natural lifetime of electronic products.
On the other hand, repair and restoration of electronics products encourages reuse which reduces the need to manufacture new products as replacements. The reduction in production requirements would also reduce pollution that may arise from the manufacturing process.
Product repair also gives the customer the option to delay purchase on new appliances and earn savings.
