good afternoon companions I need help with a tv haier model htx14s33 which turns on and off once activated and deactivates the relay I was checking I have 110v in the + b rebice diodes resistors I have 3 resistors that does not give me ohm the r562 r569 r753 I need your collaboration with the diagram of this tv to solve this fault thanks

Check if this diagram matches your circuit

Check the condition of the capacitors installed in the auxiliary sources of the Chopper transformer
What voltage is obtained in the collector of the horizontal driver transistor in both STAND BY and the ON command.
If possible, check the good condition of the FBT with a flyback tester.
Check the TSH

companion I need to know that what are the values of the resistors already named those that are in the chassis the colors are not identified the r753 heats up too much that goes to the emitter of v753 -1815 and doubled the voltages that leave the choper that voltage is 16v that come to these resistances the 3 resistors work in parallel thanks for your collaboration
