Hi,you might wish to unplug the TV for an hour or more. If this power reset does not allow the TV to turn on component failure is indicated. These sets are assembled using the wave soldering process they are known for having cold solder connections.
The safety circuitry shuts the TV set down or will keep it from turning on when it detects a problem. This model of TV has over 2,000 parts, which includes millions of transistors inside the integrated circuits. The capacitors will change value, leak and become defective. Resistors will change value and burn. Diodes and IC can go bad.
This may have a domino effect and cause other parts to fail. Replacing one defective part may make the TV operate for a short time but the part will fail again if the parts that caused the failure to begin with are not replaced.
The only way to know for sure which parts that are no longer within factory specs and for a proper repair all the electronics must be diagnosed by someone with the correct electronic test equipment specifically designed for TV service and the skills to use the test equipment. I wish I could tell you there was a quick fix or button to push that would fix the TV but that is not the case or the solution needed to get the TV operating correctly.
Vertical amp chip needs re soldering.--- very common !
Vertical amp chip has failed and needs replacing !
Failure of electrolytic capacitors in vertical circuit
Failure of resisters that supply volts to the vertical circuit
Failure of deflection yoke ( not very common )
Also it might be a convergence board failure. Changing one board will not necessarily fix it. It is recommended to change all 3 boards in the unit. many try this as a DIY and fall afoul because it is a specialist job to retune and reset the parameters. The cost then becomes greater than if a tech did it correctly the first time. Be advised it is not a simple DIY.It requires soldering and desoldering skills, specialized tools and a knowledge of circuit diagrams.
Please rate my help++++Thanks for using FIXYA
