Thank you for the answer, but i got for flat tv but mine is crt tv.so is it apllicable to that crt tv also.I got LG 29 INCHES FOUR YEARS BACK, NOW IT IS GIVING A PROBLEM WHEN I ON THE TV ITS OK BUT A


Hi Babu

Check all the solder terminals at the CRT base card. If any of it get loose at the solder terminals, this kind of fault can happen. It is very difficult to detect a dry solder terminal, as it will be microscopically small. can\'t be seen by naked eye. To this type of fault, what we technicians do is, to resolder all the suspected solder terminals. In 90% of this kind of faults, get rectified by this. You too can try this. Be sure not to short circuit adjacent solder terminals to make a short circuit by any solder bridge short, when re-soldering. Electro help

I got LG 29 INCHES FOUR YEARS BACK, NOW IT IS GIVING A PROBLEM WHEN I ON THE TV ITS OK BUT AFTER SEVERAL MINUTES THE PICTURE BECOMES GREEN AND PICTURE COMES LIKE NEGATIVE IN COLOURS. WHEN I SWITCH OFF


Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

LG LCD Tv has sound but no picture only colour vertical lines. Can be fixed?


If your screen has a picture in the left corner with a small square with lines on it but still has sound...try this....

unplug your TV itself from the power source, then hold down the power button on the tv itself for 1 minute, then release.... Plug the tv back in and see if the issue is resolved. I just called LG customer support and a woman walked me through this process and it fixed the issue !!!! Hope this helps..

Sony Tv 29 Inchs, The Picture Keep Swiching off and replaced by fable shadowi pinky multi colour light


Your symptom description is a little vague. Is there sound? Is there a full screen? Assuming there is a full screen and sound I would look for bad solder joints on the boards. Particularly the CRT board but really just resolder all the connections in the set. The KV series has been plagued with more than their share of bad solder joints. Give this a try first and if this doesn't solve it give us a more detailed explanation of the problem. Good luck.
