Sounds like The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main 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. Pull up older posts. http://electro-medical.blogspot.com/ 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. Search the site by type in the "brand name" to your device; in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

HI, I'm not familiar with this brand set but in most cases, you can't replace a main board from another size set and have it work. I'd get the right board and see if that fixes it. I'd say the power supply voltages are ok, anything within 10% of rated should be ok, but the voltage to the tcon doesn't sound right, again a main board issue.

In order to help I'll need the model number

Your TV has gone into service mode now and the colours that are showing up on the TV screen is a test pattern.To stop that yo need to unplug the TV from the power outlet and the wall and hold down the power button for 20 seconds.

It's your LED lamps that have failed but on a smaller set like this it may not be worth repairing as a new set is real low cost

That has to be one of the longest questions I've seen on here but unfortunately it doesn't help figure out what's going on, you've replaced the power supply a couple times, but you didn't say anything about testing the 5 and 12 volt rails to see if you have the correct voltage and if it's free of ripple. Have you tested the "on pin" on the power board to see if the power supply is being commanded to come out of sleep mode and turn on? Another thing to test is the on command to the main board, I'd have to pull a service manual to see what it should be but generally it's around 2.5 volts on most Funai brand sets. To be able to repair a TV it generally takes some electrical engineering knowledge and takes more than just replace some boards and hope it helps.

Hi Keith, your set has two backlight circuits, one side sounds like it's working however the other string has at least one diode that's either open or several that are shorted, and the overload section of the backlight inverter are shutting down the negative side of the supply causing no backlights. This is why you see one side come on for a moment then shut off, new strips will fix the TV

backlight may have gone if your tv has one

Question edited for clarity and typos Power cycle the television by removing the mains plug and waiting 5 minutes before powering back up. It you use cable or satellite, do the same with those. If it still does it, there is an internal board or component failure. https://www.fixya.com/support/r29790007-repairing_own_television ..
