Answer:

Assuming that TV was working fine and it stopped working when you restart or after power shutdown. Flat Black or blue screen or snow are all seems to be having HDMI cable sync issues. It can be fixed based on the model of the TV and connectivity it is using.

I would suggest to start with very basic step and should go step by step unless we narrow down the problem.

Turn off all the components, unplug the cables and plug them back by leaving HDMI cables intact. So this process will reset all the units and may help in renegotiation.
Plug all the cables and Turn on the TV. Plug all other components like sound receiver and source device and Turn on the power. This may solve the problem.
If issue still persist. Unplug and Plug back HDMI cables and surrounding components in HDMI path. It may solve the issue.
If the issue still persists, then change the HDMI cable itself and try rebooting all components.
If input is changed then it might have caused the issue. So identify the cable from the receiver to the TV. figure out its input and change the TV input to that value and it will work.
In some TV's if power reset happens, It may revert to TV mode then change the video input based on your TV model.
If the receiver is connected to TV via Coax then change the channel as per TV guide.
If the receiver and its component is using AV or HDMI then use TV remote to change the input source until correct feed is found.
If issue still persist, check the cable with another TV and see if it works. If its not then cable is at fault.
If the cable is fine then change the TV and try above steps.If it works then TV is at fault.

Describe the user interface in other high-technology devices commonly found in the home or office, such as a smartphone, HD tele

Vadim26 [7]

Answer:

Explanation:

Different technologies use different user interface designs in order to make the user experience as easy and intuitive as possible. This varies drastically from one device to another because of the capabilities and size of each device. If we take a fitness/smart watch into consideration, this device does not use pop up menus or side scrolling menus but instead uses large full screen menus where each option nearly fills the entire screen. That is done because the smart watch screens are very small and making everything full screen makes reading and swiping through options that much easier for the user. If the user interface were the same as in a television or smartphone it would be impossible to navigate through the different options on such a tiny screen.

Can someone help me with Exercise 7.1.5: Initials on codehs.

Ber [7]

7.1.5 Codehs:

Write a program that gets a string containing a person's first, middle and last names, and then display their first, middle and last initials. For example, if the user enters John William Smith, the program should display J. W. S. [In python]

Answer:

first = input("First name: ")

middle = input("Middle name: ")

last = input("Last name: ")

print(first[0]+". "+middle[0]+". "+last[0]+".")

Explanation:

This line prompts user for first name

first = input("First name: ")

This line prompts user for middle name

middle = input("Middle name: ")

This line prompts user for last name

last = input("Last name: ")

This line prints the name initials

print(first[0]+". "+middle[0]+". "+last[0]+".")

Assume that a file containing a series of integers is named numbers.txt. Write a program that calculates the average of all the

Anna [14]

Answer:

Program in Python:

file = open("numbers.txt", "r")

count = 0

isum = 0

content = file.readlines()

for nums in content:

num = nums.rstrip('\n').split(" ")

for i in num:

isum= isum + int(i)

count = count + 1

print("Average: "+str(isum/count))

Explanation:

This line opens the file named numbers.txt

file = open("numbers.txt", "r")

This line initializes num to 0

count = 0

This line initializes sum to 0

isum = 0

This line reads the content of the opened file file

content = file.readlines()

This iterates through the content of the file

for nums in content:

This removes trailing new lines and blank spaces from each number

num = nums.rstrip('\n').split(" ")

This also iterates through the content of the file

for i in num:

This calculates the sum of the numbers in the file

isum= isum + int(i)

This counts the numbers in the file

count = count + 1

This calculates and prints the average of the numbers

print("Average: "+str(isum/count))
