Repair LCD Power Supply The Easy Way

Troubleshooting LCD monitor power supply pack is easier than kuala lumpur massage crt monitor power supply. It is small and compact and usually has only one output which is 12 volt and range from 2 ampere to over 4 ampere. Some designed have 18 and 24 volts also. Nowadays most LCD power supplies are build into the main board such as the Dell E151FP LCD Monitor while the older type were separated as power pack module.

The power pack module type is easy to diagnose because you can replace another working unit just to penang malasia sure is the power pack that giving problem. You may also use an external dc power supply to power up the LCD to confirm if the power pack is faulty. If you do not have the external dc power supply, you can always use this method to isolate the problem especially the symptoms are no power, low power and power blink. Using the rear light bulb (12 volt) from a car and connect it to the power pack output jack. If it light brightly then the power pack is okay. If it blink or dim the power pack have problem. Why have to use this method to test it? Because, if there are components shorted or leaky at the LCD main board, it will aztech adsl the power supply performance.

From experienced, most of the LCD power supply problems whether in the power pack or built into main board were broadband phone cable to the failure of electrolytic capacitors (most probably due to heat) in the primary and secondary section. Most of the capacitors have a high ESR which causes the power supply to produce low output, blink or no power at all. Typical value electrolytic capacitors in the primary side are 47 and 100 micro farad 50 Volt and the secondary sides are 1000 to 2200 micro farad 25 volt. Sometimes you can see the broadband adsl cable top casing became bulge and the sleeve that covered the capacitor casing turned into darker color like brownish.

The power section in some of the LCD screen are still using the UC3842 pulse width modulation (pwm) ic. This type of ic is quite easy to find in the market compare to some power ic which is very difficult to get. Samsung 153V LCD monitor is using the TOP247F power ic which is quite easy to troubleshoot if power fail in this model. Some power pack that came in only have minor burnt and after cleaning it and replaced the fuse, it will work as good as the new one.

Troubleshooting LCD power supply is not that difficult provided if you know how a power supply work. If you are unsure of how to troubleshoot power supply, I urge you to read all my power supply articles at the power supply page. I will continue to post more power supplies articles at that page and hope you could drop by more often to check out my website.

Colorectal Cancer Part 2: Medical or Herbal Treatment?

The primary therapy for colorectal cancer is surgery. At an fuck streamyx stage, surgery cures it. However, more often than not, doctors would refer patients to the oncologists after the surgery. And oncologists, from my experience living in the developing country, would invariably ask patients to undergo chemotherapy even if the cancer was caught?at an early stage. The rational is preventive, i.e., to provide protection?against future problems.

The cytotoxic drug, fluorouracil, commonly known as 5-FU is the gold standard agent used. This drug was discovered in 1957 by Dr. Charles Heidelberger of the University of Wisconsin. According to Joel Hardman et al. (in The Pharmaceutical basis of therapeutics), 5-FU produces tv phone broadband partial response in 10% to 30% of patients with metastatic cancers of the breast and gastrointestinal tract. The cytotoxic activities of 5-FU is enhanced when combined with agents like leucovorin, interferon, broadband phone companies cisplatin, etc.

In 1975, Dr. Charles streamyx announcement of the Mayo Clinic in Minnesota, USA, found that survival of Dukes C colon cancer patients could be prolonged when treated with a combination of 5-FU and levamisole. Levamisole is a drug used in sheep, swine and cattle to control stomach and intestinal worms. It is also commonly used to treat nematode parasite infections.

In 1998, it was found that a combination of 5-FU and leucovorin increased the five-year survival of patients with Dukes B and C colon jalan malaysia Leucovorin is the active form of the B complex vitamin.

Based on the above observations, chemotherapy had been touted as the necessary adjuvant treatment after surgery for colorectal cancer. It is claimed that adjuvant chemotherapy prolonged survival of cancer patients. In addition, it is said to promote the patients?quality of life (i.e. if you believe that malaysia hotel chemotherapy is a pleasant experience!).

In cases where 5-FU is not effective other drugs are used. For example, Irinotecan (Camptosar, CPT-11), Oxaliplatin combined with 5-FU, etc. A recent development is the use of oral chemo-drugs like Capecitabine (Xeloda) and UFT (a combination of uracil + tegafur).

From the above, it appears that the state-of-the-art medical treatment of colorectal cancer is well grounded on solid research data. That is the perception the medical community would want the world to believe in.
I invite you to read the one of the many stories I have recorded from my ten years working with alternative and complementary cancer therapies. Give this story some serious thought. Form your own opinion as to what you would want to do in the event that you suffer from colorectal cancer.

Case Study: Colon cancer -- surgery -- declined further medical treatment -- on cable internet providers nine years now and doing great.

It was some years ago that I last spoke to Joan, a lawyer friend of mine. Then one fine morning in January 2005, I had a surprised call from Joan. As we spoke she reminded me that her uncle was doing so well on the herbs after having a surgery for colon cancer. To be honest, I have totally forgotten about this case. After the conversation, I decided to write to Bob, the patients son to seek for more clarification. It was indeed wonderful that Bob was very co-operative and took time to reply to my enquiries. The following is our e-mail communication.

Dear Bob, for my record, may I ask you a few questions:

a) When did your dad has his cancer? What was his age then?

Bob: Sometime in the end of June 1997. He was then 67 years old.

b) What cancer? Colon or rectum?

B: Colon cancer.

c) He had an operation?

B: Had the operation in Singapore General Hospital on webmail tmnet streamyx July 1997.

d) After the surgery, did he do any chemotherapy or radiotherapy or both?

B: He did not do chemotherapy or radiotherapy as advised by myself after reading your book.

e) After he had the operation, what did the doctor say about the stage of the cancer?

B: It was in the early mid-stage. Luckily the cancer was detected early.

f) Was the cancer confined to the colon or has it spread to any other organs?

B: The cancer was confined to the colon although there was a spot in the left lung. Luckily the cancer did not spread to other organs.

g) Did the doctor ask him to go for chemotherapy or radiotherapy?

B: The doctor asked him to go for both therapies but I have discussed with my dad and we decided against it because he was rather weak.

h) I assume that when he declined all medical treatments, you (not your dad?) came to see me in Penang? Sorry, I cant remember this case.

B: We did not get to see you in Penang because my dad was sick. We communicated by faxes and telephones most of the time. My aunt (Joan, the lawyer above) was the main coordinator during this time.

i) When did he start taking the herbs?

B: Yes! He took those herbs that kuala lumpur malasia prescribed by you prior to the operation.

j) Was he taking anything or doing anything else besides my herbs?

B: No other medications or herbs were taken.

k) How is he now?

B: My father is in good health as he has changed his lifestyle. Walks regularly and practices careful food consumption.

It has been almost nine years now, since Bobs dad was diagnosed with colon cancer. He was on herbs and changed his lifestyle and diet. It was indeed worth all the efforts. I would not venture to say that Bobs father took a calculated traders hotel kuala lumpur (gamble some may want to say). This is because it has never been a gamble for patients to opt for another route to their healing. Or could we turn it the other way round? Could it be a gamble if one were to take the established, popular, established route?
