Suddenly hor. lin. became "narrowed", smell of overheated element
Hi! Suddenly horizontal linearity became "narrowed" to 80% of monitor width (1" width of vertical black bars on the left and right side of the screen). The linearity is different through the width of the screen. Smell of overheated element from inside of the monitor. I have no service manual of the monitor. Bye, Darek53

if the area is 1400 square feet the lineal is 149.6 ft outside edge from a square 37.4 feet on a side, to 2802 ft outside edge from a rectangle 1400 by 1 foot wide. After that the calculation is the number calculated by the formula below multiplied by two plus the length of the ends. The narrower the strip, of course, the longer the linear distance until you have an infinite length line of infinitesimal width and you have created a perfect mathematical construct of two dimensions
The calculation for determining the lineal distance that the internal area can be converted to is:
L=1400/n where n=the width of the strip required in feet
eg in 1foot wide strips n=1 so L=1400, in 6" wide strips N= 0.5 so L=2800.
You get square feet by multiplying linear feet with another linear feet. 18 sq.ft = 3 lin ft x 6 lin ft or 2 lin ft x 9 lin feet or 4,5 lin ft x 4lin feet.
Sq ft is used to quantify surface area where linear feet quantify distance but lin ft x lin ft gives you square ft (surface area)
Linear feet are a measure of length (no different from feet); square feet measure area. You cannot simply convert between measures of different kinds of quantities;the connection between them will be specific to a particular problem.A practical example in which this question can arise is in buying countertops for a kitchen. Some materials are sold by the square foot; others (basically those that are extruded, so they come in standard widths) are sold by the linear foot. In order to compare the two, you need to compute the area and wall length for the countertop you want.You can't convert between the two. All you have to do is to make the appropriate measurements so you can calculate the price of each item.The terms used in the lumber industry are a bit confusing.There are two terms that I think you might be mixing up.A LINEAR FOOT is simply the length of a board. If you want to know the area or volume of the board,you need additional information. For instance, 6 linear feet of 1-by-12 has an area of 6 square feet (12 inches = 1 foot, times 6 feet), and it's 1 inch thick, so the volume is 1/2 cubic foot (6 square feet times 1/12 foot). But 6 linear feet of a 1-by-6 board would have half the area and half the volume.A BOARD FOOT is equivalent to one square foot of a 1-inch-thick board. In other words, it is a square-foot-inch (ft^2-in), or 1/12 cubic foot.Linear feet are used for the pricing of a single size such as two-by-fours. Board feet are used for larger lumber that you are more likely to want to compare directly with different size boards .To sum up, neither a linear foot nor a board foot can be converted directly to square feet. A linear foot is a linear (length) measure, and a board foot is a volume measure. You need to know your particular board to do anything more, such as find the area.an example with an" L" shaped countertop will betwo rectangles are 24 by 80 inches and 24 by 36 inches. Thus the area is: 24 * 80 + 24 * 36 = 24 * (80 + 36) = 24 * 116= 2784 sq. in.To get it in square feet, divide by 144: 2784 / 144 = 19.33 sq. ft.The linear measure of this countertop would be 60 + 80 = 140 inches = 140/12 feet = 11.67 feet
hi, your monitors horizontal deflection side have some problem. you have to check the horizontal width cotrolling transistor mounded on the aluminum heatsik near the lot( line output transistor). also check the three mosfets which adjust the width for different resolutions. there are three such mosfets in the horizontal section.
fist of all replace the width controlling transistor in the heat sink. photo of mosfet and transistor is added for reference. not the exact number. ok
You can try and replace the hor.out but before trying it again check for bad solder joint in the hor. deflection circuit .
If the hor. out goes again then you have a good chance that the h.v transfo (flyback) is gone as well.
Check for overheating of the hor. output once its working again,it could be sign of a faulty hor. drive or pincushion circuit.
Hope this will help. Good luck
On the monitor there should be some buttons that allow you to manually configure the width and hieght that the screen comes up with.
Does you screen come up squashed but you can still see everything or only 1/3 of the screen is shown and the rest is black.
Hello, I think you have a faulty "horizontal width" or horizontal
linearity preset pot. This pot will be located on the main PCB
and you can adjust it with a small screw driver, when you do the
picture will shift from left to right or vice versa, or move back to fill each side. If it wont hold after making the adjustments then the pots ( potentiometers) need replacing, which means unsoldering them from the printed circuit board( PCB) and take them in to your local radio shop for new ones. By the way you might need 2 pots ( 1 for the WIDTH and 1 for the LINEARITY)
My LG tv has suddenly got a problem with the picture. Whilst watching the tv with no problems at all,
the picture was suddenly reduced to a thin vertical line down the centre of the screen
and an awful smell seemed to come from the tv
There is a short ckt in your tv in horl. section.
1 isolate power from horizontal section.
2 check for normal output from power supply.
3 check parts in horl output section
a hor.output transistor
b diode & cap in h/output trnsformerckt.
c check for print.
d if all are ok check for eht transformer.
e if every thing becomes then reconnect hor output section supply.
f put on the set.
