What chassis does the TV use? Is the DTB 14V1FS model correct? ... If the transistor is short, it will always be found around the component in poor condition too ... You have to work with a lamp in series to avoid greater evils at the source.

if the model is correct, the chassis would not have to check it ... where do I put the lapara in series?

this is the chassis CN-001A

If you found the MOSFET transistor in short, it is very likely that the hybrid IC is in poor condition too ... Check fuse resistors, for example R804 ... Check the D822 avalanche diode ... Serial lamp is a working technique for Repair the switched sources of the TVs, there are other methods, but I learned only this method. You have to build on basic repair skills at least to receive a guide, otherwise it is very complicated to work like this.

I already investigated the lamp in seie, you have to put it in series to the power to the TV, tomorrow I measure those components and I will warn you

Good morning bro, check the diode and it's good, the resistance is red-violet-gray 2.7 teraonhm .. I don't know how to measure it because my multimeter reaches 200M and the icon you say I don't know what it is, if you give me the code or the number as well as the diode is easier to look for ... thanks

Ok, the resistance that I told you before is of very low value, you are wrong in your appreciation about the unit ... The value of it is 0.27 Ohms on the 1X analog tester scale enough to measure it, in The scale of 200 in the digital testers is enough and left over, if resistance is not measured at these scales, it is because it is open. The IC is a hybrid DPM-001TI ... This IC is scarce, and if there are any they are very expensive ... If you do not have solid knowledge in the matter, and it is very complicated to assist ...
Luck.

thanks bro, if the resistance is open, and I know which one you say ... tomorrow I buy the resistance and the amount and I tell you ... for the knowledge I am starting on this bro but I learn fast .. thanks for your help and patience
