MY tv wont stay on thelight goes out still have sound it will come on and of three times before the light stays off but there is still sound
i opened the back changed the fuse still the same-thing thought it maybe the motion censer every thing works
Can you please get me the model number off of the back of the TV?
Thank you for the reply.
Can you please tell me if the light on the set is blinking continously, or in a pattern (such as 3 blinks, pause, 3 blinks, pause, etc.)?
If you press MENU on the TV, will the MENU appear on the screen?
When i turn it on the red light blinks about 3-4 times if i press the menu
button while or in between those fist on and off i can see the menu, but after the third time the light goes off and i cant see any thing
Please disconnect the set from AC power, then press and hold the power button on the TV itself (not the remote), for 10 seconds. After another minute, plug the set back in and press power once. Do you still have the same problem?
yea it still does the same the red censer light blinks 3-4times
Unfortunately, this indicates a failure within the TV that requires service.
Do you know how to use a DVM, and are looking to repair this yourself?
Or are you looking for a diagnosis and repair estimate?
i would like to repair it on my own, i have a dvm an old one but i am not that well with it how much am i looking at
Unfortunately I do not have good news for you. There is no sequence of buttons you can press the reset the TV, and it will require circuit testing and component replacement to operate properly again.
There are basically three problems that would cause this, the Power Supply, the T-Con board, or the LCD panel itself has failed. Voltages need to be measured at the power supply outputs, using a DMM with nothing connected to it but AC Input. If the readings are proper, then the other boards need to be connected one at a time, until one causes the voltage to shut down at the output. Price to replace the power supply is around $200 parts and labor. If the supply outputs power with all of the boards connected, then the T-Con needs to be tested. The T-Con will run you around $150 to have replaced. If the T-Con tests good, then the LCD Panel has failed and will cost you more than a new TV (around $500) to have replaced and it is not cost effective to repair this set. I wish i had better news on this set, but the symptoms you're having indicate a failure in one of the components responsible for powering, and processing the LCD panel itself (including the LCD panel).
If you do not have experience testing live voltages on a circuit board level, then I would suggest using the link below to locate a tech in your area:
