Using Service Modes and Service Manuals

Most service manuals or service modes repair tips are very useful these days especially if you are very inclined to repair of the digital age electronics system. Almost all brands of electronics appliances and gadgets are equipped with service mode guides that the service technician can use for repairing troubles that are specified in the manual itself. In a revolutionary world or the repair industry in electronics, it is important that service technicians keep themselves up to date when matters of repair are on the table.

There different brands that you can delve yourself and update your knowledge upon ranging with different brand names like what I will be listing below.

  • Sony Service Manual
  • Sharp Service Manual
  • Sanyo Service Manual
  • Hitachi Service Manual
  • TCL Service Manual
  • Goldstar Service Manual
  • Nipponstar Service Manual
  • JVC Service Manual
  • Samsung Service Manual
  • Toshiba Service Manual
  • Sears Service Manual
  • Polytron Service Manual
  • Promac Service Manual
  • Philips Service Manual
  • RCA Service Manual
  • LG Service Manual
  • Panasonic Service Manual
  • Daewoo Service Manual
  • Visio Service Manual

Each of this television brands have their own unique TV manuals as specified and I will be providing details later in my coming updates.

Basic PC Troubleshooting - Beeping Sound Trouble



Beeping Sound Troubleshooting:

When you encounter a beeping sound trouble in your PCs, first thing that comes into your mind is that you need to let an expert see what's wrong in your PC. Wrong choice i would say because if you are having troubles in your PC with the same instance as what i am describing in this post. Here are some basic but most often useful tips that i believe may help you out with what you have been experiencing.

  1. Try first to open the case but make sure that the PC AC cord or plug is unplugged in the 220-volt line or if you are using a transformer, unplug your PC from there.
  2. See if too much dust has accumulated in the mother board which is the only parts board i you can see inside. Remove the dust using a small paint brush but be sure to gently do it especially if you are to remove dust from the main board itself.
  3. When you see clearly that the main board and the wires are cleared of dust, try to remove the memory card first and be sure to remember the correct place or slot of its original placement.
  4. Re- place or put again the memory card after cleaning the contact point which is the copper side colored like a gold and try rubbing it with an ordinary eraser in its terminals.
  5. Avoid touching the terminals after cleaning it or it may cause loose contacts and be sure to re- plug it tightly in its original position.
After doing the procedure stated above, try and plug the unit to the AC line (220 Volt) or transformer if you are using one. If what you have done did not cure the trouble, don't worry because we still have many more to important things to do aside from the above mentioned procedures.

Be sure to again remove the plug from the AC line (220 volts) or transformer if you are using one before we proceed to the next step.

The Power Supply Approach:

  1. Next step to do is to remove the power supply plug from the terminal jack where it is plugged in the mother board and see for some dust that has accumulated for the years that you haven't been doing the regular maintenance of cleaning the mother board.
  2. Remove the dust using again the small paint brush that you used in the first procedures above.
  3. Re-plug the power supply and be sure that it fits well slots provided for it in the mother board power supply jacks.
  4. Apply just enough force in plugging it back and see to it that the line in the power supply jacks meets with the line in the mother board jacks.
  5. The power supply plugs have locks that should be well secured on the other end of the jacks in the mother board. Be sure that they fit well or it may cause even more trouble to your PC.
When all else fails using these procedures that i have provided you, i bet you really need a more professional approach to the problem that you are encountering. This may take either seeking the advice of a qualified PC serviceman or replacing the needed parts and buying a new replacement part for your PC. You can also try logging in or registering to some PC guides and troubleshooting forums.

The EPROM Basics, Tips and Facts

EPROM - EPROM is the short term for erasable programmable read-only memory. EPROM is actually some sort of a memory chip that has the capabilities to retain data that you can input to it even when you put its power supply in switched off mode for a long time. A non-volatile material, it is usually called chips as a characteristic of a miniature of compacted parts put together. It is actually combinations of different and numerous floating gate transistors having each their own unique and individual programs done by an electronic device that supplies a much higher B+ or voltage that is not commonly used by other ordinary electronic circuits you can conventionally find and commonly see in your everyday lives as electronic masters.

Erasing The EPROM Data:

One way by which you can erase such program that you enter or is input in the EPROM is through exposing the chip to a strong ultraviolet light or sometimes called as UV rays. A UV light that commonly consists of a wavelength 235 nm that belongs to the UVC range of UV light is usually used to do the job.

Special Characteristic:

It is so easy to distinguish and differentiate an EPROM chip from an ordinary chip. Usually, it has a visible and easy to notice feature that is easy to recognize by its transparent quartz window on top of its package mostly near the center where you can also view and see clearly the silicon content of the chip.This quartz window where you can see the silicon inside is where UV is passed on to erase the program. So this explains why we can see through a clear quartz glass like window in most EPROM chips. It is clearly then not just some design to amaze electronic masters but to a special purpose it serves in programming and erasing programs at the same time. EPROM unlike the flash drives that exist these days are read only memory chips unlike the first where you can read, erase and reprogram datas.

The Google Update Took Effect

When the Google update took effect, i had one blog with a page rank of 1 which is seoptimizers. after 3 more days i recieved another Google update incentive which got my three other blogs int to PR. seoflea has a PR 2 right now, my glasskitchenseo also arrived at the end of the day at PR 2 and my Amusement Park site with another PR 1 ranking. Overall assessment has me jumping up for joy because the perseverance that i have been doing all the time had the best results that i have been longing for which is to achieve PR for my sites.

Although PR is not much of a must for me, i made it a point to be grateful at what has been the resulting factor of my hard work. I got what i have always been visualizing my sites to have because i have worked hard for them and i deserve it with all due respect.

After this positive development that has happened to my sites i am looking forward to seeing things go my way as in seeing myself studying some more html and a little of web designing and graphical aesthetics soon using photoshop. I am pretty sure that me given the right and time i could really see myself sitting at my own desk in front of a flat screen pc monitor with the highest capabilities of a pc possible to be owned by a webmaster like me.
