Question about Televison & Video
I have encountered the same problem with one of my televisions. The culprit was overheating capacitors. Bring your TV to a local shop or a technician. Tell them that your TV has bad capacitors. Capacitors are cheap so having this TV fixed wont cost you a fortune. I hope this helps. Have a great day.

There are could be more than one cause of the problem. And you need to check the all the boards first before deciding to replace your TV.
Please check first the following and you might save some money:
1. Check the power supply board: This part usually goes bad due to overheating and faulty components. You must check for brown spots on the boards , that are signs of overheating.
2. Bad components: Tthe common components that goes bad ares the Capacitors, Resistors and the Relay. You have to check if there are bulging capacitors or burnt resistors or bad relay.
3. Cold Solder Joints: you must be very careful working on the power supply board as it does have high voltages they can be very dangerous to the inexperienced user. Never test anything with the power on or connected.Use anti static protection straps and gloves around all the chips and microprocessors to avoid damaging them. Check all the other boards for the same problems. If you can find no problems, Then it is time to get help from a service center where they will have all the necessary testing equipment, To give the unit a more thorough testing for faulty components.Hope this helps you with your problem.
Once you found the cause of the problem, you may now replace it by yourself. But you have to make sure to use the same value of capacitor or resistor.
It would always be best to consult a TV technician if you don't have the right equipment.I hope this would help you save some money.
Have a good day!
