Dell 17″ (Likom L705XXX) Monitor With No Power Symptom
This DELL 17” Monitor (Made in Malaysia under LIKOM model L705XXX, product no: L7055LP) came in with no power symptom. Normally after opening up the cover I would look at the power supply (primary side) for any burnt and cracked components first. If there are darkened area and burnt components, I would tell myself that this Monitor needs a little more time to repair it. If it is not (component’s intact) I would usually begin to discharge the filter capacitor and start checking the fuse. Continue reading »

Computer Monitor Display Problems Caused By A Defective Screen Grid Voltage (G2) Capacitor
Computer Monitor display problems such as no display with high voltage symptom can be caused by many reasons. A defective picture tube, a faulty video preamplifier IC, a missing heater voltage, torn signal cable, negative G1 voltage became too high (-120 volt and above), CRT board problems, a missing or low G2 voltage and etc could cause no display but with the present of high voltage.

All cathode ray tube monitor (crt) have a sticker sticked on its crt coating. Those words or characters printed on the sticker are the type number of the picture tube. All cathode rays tubes, whether a monochrome (black and white) or colour crt are identified by a specific code consisting of numbers and letters. The cathode ray tube monitors codes are different from each other because different picture tubes have different characteristics. Television codes are more or less the same as the monitor codes.
For instance, most color monitor cathode ray tube has the designation code such as the M36AFA63X03. There are six meaning (parts) M/36/AFA/63/X/03 in these codes as explain below: Continue reading »

Volitans has published v2.0 of SMART Utility, a diagnostic tool for hard drives. The software taps into the SMART monitoring technology built into hard drives, and presents status information in a more convenient and legible form. The app additionally attempts to warn users about impending disk failures, with the aim of allowing time to transfer material to a different location.
New to v2.0 are the ability to run built-in self-tests, and preferences that can limit alerts to the discovery of new problems. Temperatures can now be displayed in Fahrenheit, and Growl users can receive notifications for scans, updates, and impending or total failures. SMART Utility requires Mac OS X 10.4 or better, and costs $25.

If a system is composed of several parallel or redundant components which can be removed without crippling the whole system, start removing these components (one at a time) and see if things start to work again.
Example 1: A “star” topology communications network between several computers has failed. None of the computers are able to communicate with each other.
What to do: Try unplugging the computers, one at a time from the network, and see if the network starts working again after one of them is unplugged. If it does, then that last unplugged computer may be the one at fault (it may have been “jamming” the network by constantly outputting data or noise).
Example 2: A household fuse keeps blowing (or the breaker keeps tripping open) after a short amount of time.
What to do: Unplug appliances from that circuit until the fuse or breaker quits interrupting the circuit. If you can eliminate the problem by unplugging a single appliance, then that appliance might be defective. If you find that unplugging almost any appliance solves the problem, then the circuit may simply be overloaded by too many appliances, neither of them defective.

As Intel’s Core i7 architecture starts moving down from the high-end, value seekers can build high-performance LGA775 systems cheaply. Low-cost motherboards compete for the value crown with added features, performance, and overclocking capabilities.
