T.v has a dark area on the lower part of screen

When I switch on my t.v..the image covers small part of the upper part of the t.v. after a while..the images start appearing on the lower part. it only goes upto a few centimetres from the lower part of the screen and stops there.There is a dark layer on the lower part of the screen running from left to right.i do not see all the images. Before the problem occured..there was a power blackout.the power capacitor and the posistor went.they were both replaced and this problem has remained since then.

Picture goes dark but there is sound

There are many cause of dark picture symptom of standard television.First thing to do is try to adjust the screen control adjustment located at the flyback at the lower parts.There are two flyback adjustment the focus and screen adjustment.The upper level is focus and the lower is screen control. If check also the CRT socket board section.This CRT board is compose of high voltage terminal coming from the high voltage supply.Check if there's a cold solder in CRT socket terminal and other parts around the CRT socket.The heater supply,the RGB cathode supply,and the screen supply are the supply of picture tube to be lights up.So try to resolder those parts of the TV.Avoid short circuit in the PCB board.Hope it will help you.Thanks..

I am trying to help my neighbor. She has a Sanyo flat screen tv Model DS20930. The picture she gets is a thin line across the center of the screen.

Set the brightness, contrast and colour control of that TV to minimum. Watch it in a dark room whether ther are thin white lines across the screen, at about an inch apart, from bottom to top of the screen. If there are lines, that TV needs screen control adjustments. That is, now the screen voltage given to the picture tube went high to some reasons. If you have confidence that you can adjust it, I will guide you.
Open the back cover of that TV. Locate the LOT [Line output Transformer], usually one red thick wire is connected to the top of the picture tube with the help of a rubber ****** and clip. In most TVs it can be located and can be seen as the back cover opened. There are two variable control, fitted, integrated to LOT. Normally the upper one is marked as focus, and the lower one is marked as screen. You shoud adjust this control to avoid these lines.
It is a live service, that is the TV must be switched on during this time, and take causion in every respect not hurt by yoursef and the TV. Keep the children away from you, and an other adult person beside you is better. A liitle turn counterclockwise will remove this problem.

Tv to dark cant see nothing tv's to dim

On the back of the TV, to the right of the I/O panel, there are 2 vertical slot shaped openings on a raised bit of the plastic case. Behind the lower slot is the screen adjuster. Using a phillips screw driver, turn the adjuster clockwise to increase the brightness. Behind the upper slot is the focus adjuster.

The screen on my tv is too dark how can I set the scenn control

The back cover would have to be removed -the flyback located (the largest solder mounted component) - the screen and focus controls are located on the side of it.
Caution is required in this area since high voltage is present.

Jvc av-27432, the picture on this tv is very dark. even when you turn the brightness up all the way you can't seen any detail if the program your watching is taped at night or in a dark room. is there any...

There is a way to adjust this but it requires removal of the entire back cover-----YOU HAVE TO BE VERY CAREFUL WHEN YOU DO THIS AS THE SET HAS TO BE HOOKED UP AND TURNED ON!

IF the problem occurred over a period of time you have a good chance-----if it happened suddenly--you have a problem in the set.

With the back removed locate the HIGH VOLTAGE TRANSFORMER- it will have a large red wire coming out of the top of it that snaps into the top center of the picture tube (this is the anode lead) DO NOT GET ANYWHERE NEAR THAT LEAD WITH THE SET TURNED ON---ABOUT 25 THOUSAND VOLTS IS THERE


With the set on turn the lower control (Screen) slowly to the right until the brightness comes UP---DO NOT TURN TOO FAR OR YOU WILL GET TRACE LINES AND THEN THE SET WILL SHUT OFF!

If adjusting the master screen does not solve the problem---you have a circuit problem and the set may or may not be worth fixing. Usually if the picture got darker over a long period of time--just adjusting the screen control up A LITTLE will restore things to normal.

I cannot tell you how important it is not to touch anything in the set---keep one hand in your pocket and use the master screen slowly.

Let me know what happens and if you have any questions ask before you attempt this.

Regards, SD TECH

Dark picture


In my case, the adjustment was available from outside the TV. Sortof. On the rear of the TVabout 2 inches to the right of the coax in, there are two vertical slits on a little protrusion. Inside the slits are the two adjustment screws. The lower screw adjusts brightness, the upper screw adjusts focus.

WS-55807: Images are dark on right side of display, but will go away after 3-4 hours.

you could be on the right track get some freeze spray and go around all the parts to see if you can make it act up, same with heatgun or hair dryer when first turned on heat one area at a time to narrow your problem down

1.Are these lines only in the upper 1/3 rd portion of the screen?And is there a clear demarcation between this area and the lower portionb, where the image is perfect? 2.Or is thin Horizontal lines evenly spaced around an centimetre apart? If it is the first case, then there si a problem with your TVs SMPS. It is not generating the required regulated 110V required for the TVs functioning. If it is case 2, then there is a simple adjustment at the back - 'SCREEN'. This adjusts the Screen Grid Voltage, and by slightly lowering it, this problem will go away.
