Greetings to the colleagues in the forum, some will remind me that last year I left some questions about repairs pending, for painful family reasons I had to do it, in fact I gave these TVs because I could not concentrate on work. I am starting over and this TV arrived, the owner told me that he turned it on and smelled it burning, starting to smoke. I uncovered it when I checked it, I found two small, completely burned ceramic capacitors, I kept checking and I found a burnt resistor. The help I ask you for is if you know the value of these C450 ceramic capacitors, where VD435 mark that has the sign of a diode had another ceramic capacitor the two are small I can not tell you color because they are completely charred. and the R467, I put two capacitors that I got in a similar chassis one marks 102 x 2kv and the other 681k x 2kv I put a 12k resistor omh the TV turned on but the condensers get very hot, the TSH and its heatsink get hot. I do not know if it is a coincidence but I also have an ultra slim premium brand TV that was brought to me with the TSH in short I changed it the TV turned on but also a coil and TSH electrolytic capacitor are very hot. Colleagues of the forum I thank you very much for your attention and your help, I am waiting for your support Thank you.

You can take certain references from this diagram: https://www.electronica-pt.com/esquema/tv/generic/parker-tu2195-chassis-ph08k-n22-29801/

Companion Javier thanks for the diagram although it is not of this chassis it served me because when I saw the value of the + B on this tv it was almost 125 volt and for this tv it must be 110 volt, I realized that there was an adjustable resistance I was graduating until you leave the + B at 110 volt. Now the tv works fine, my mistake was to believe that this tv had 125 volts in the + B. It was thanks to the diagram you sent me that I realized Thank you partner and I valued your help.
