    Well, the TV was bought on Sept/2004 and die on Jan/2006. It has been sitting at a corner for the past 2 years. It is hard to believe how can a TV broke down after one year of use. Only defective parts or designs can cause this. I watched this TV roughly 3-4 hours each day. That was not excessive. It was on a surge protector. The Sony Company has Customer No Service attitude. It is selling products that are so unreliable. The Customer relation people has the worst attitude ever. It even tells me that after authorized repair the warranty is one month. What a joke? One month warranty for a TV repair. I can do a better job myself. Shame on Sony and its customer relation dept.

It is impossible to guess at the parts without actaully troubleshooting the set with the proper setup.

From past experience, the areas that the fault for this normaly is, are the horizontal output ampliifer, main power supply, and sometimes there may be a problem with the vertical deflection amp.

In the horizontal output stage, with this set many times I have seen the flyback and output transistor go defective. When there aer problems in these areas, most of the time the power supply is damaged.

What is interesting, is ou say that this set is about a year old. In actual fact, this model is about 5 to 7 years old.

Considering the age of the set, I would be seriously looking at getting a new set rather than put money in to this one. This model is obsolete, and many of the parts for it are no longer availabe.

I have a lg tv 60 inch tv ln5600 when powering on red stand by light blinks 3 time then no light pic or sound not backlight and no image when using flashlight treid replacing power board does same


Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

My sony wega kf-50E200A tv keeps turning off. during each cycle the green light blinks 42 times and the tv comes on again for about 3 minutes and it happens all over again


More than likely the power supply is defective, but without testing and the repair manual that is just a guess, you make the decision to replace or repair the TV.

Samsung TV Displaying Dual Images. It appears as 2 of the same images offset from each other. There are also some lines in the images. Talked to samsung and they wanted to send a tech but I simply can't...


Overlapping video signals are generally adjustments made when turning various pots on the rear circuit board. You may need the service manual to follow the directions on how to reset and stabilize the picture. If you cannot be your own technician; you have no choice or other options.
