This TV was brought to me because I didn't turn it on but when I uncovered it, I see that it lacks the vertical IC and the Horizontal TS asked the owner and told me that a supposed technician had checked it in his house and that he never saw it again, I imagine he who took these parts. I ask for your help fellow forum members to find out if anyone knows which vertical IC and which horizontal TS carries this tv Thank you colleagues, I hope your help.

Unlink the actual load (TSH and FBT) from the + B source, place a focus as a false + B load and thereby check the stability and performance of the + B source. Once this source test has been verified, you can proceed to place the missing elements safely and proceed to the ignition test.

Companion javier that was what I did to locate the damage that this TV had, I unlinked the + b from the horizontal and measured the voltage of the source and there I realized that the damage was in the horizontal part I looked for and I got two bad components I changed them and turned on well. Thanks fellow Javier.

This is a list of components that I found on the WEB,

Those components are from this tv model? companion by chance knows any replacement for the Ts Horizontal Q401 2001HI? to see if I have that transistor. Another companion favor will have the diagram of this tv model? Thank you for your help partner neg2013.

These data were taken by a colleague who makes a query to get the service manual, supposedly could not get, (It seems to me) but provides a list so that the one who contributes the diagram also takes his time and makes the correct contribution. By TSH I can replace it at my discretion with any transistor that does not have a 1500 volt damper diode for 10 amps.

It seems to me that the candidate can be for example the J6810 (to dry without later letters) This transistor is more commercial in my locality, these are used by TRC TVs a little more modern (SLIM) for example ...

Thank you, my partner, that data is useful because I do not have a horizontal without a damper. I am going to look for it to see if I get it because here in Venezuela what is achieved is very expensive and most of the time there are not, then I tell you how it was. Thanks again mate.

Companion neg2013 I thank you for your help you mount the missing components then I did not want to turn on even the stanby turned on, I did the test by disconnecting the + B from the horizontal part there just turned on the stanby and the source voltage it stabilized, there was no doubt the damage was in the horizontal part I started looking for and I found the CR401S short is a 471x 2Kv ceramic capacitor goes from the TSH collector to ground and the broken L811 coil I changed those components and the TV turned on perfectly. Thanks mate, I already value your help.

This is the friend diagram, what if I also tell you, is that the stambye led should be on minimum

I have NOT verified that partner tomorrow I will do it. Greetings fellow Francisco, I tell you later because I have to get the horizontal ts that I don't have.

Companion leasmacruz sorry, the comment where I put Francisco was for you I got confused because I got a comment from fellow Francisco at the same time with the diagram too, but as I said in that comment I will verify the stanby because I have not tried to connect it after I saw the missing components. Thanks mate and sorry for the confusion.

Companion I already repaired this TV and all thanks to the help that both you and the other colleagues gave me the explanation of how I did it is in the comment I wrote for the partner neg2013. Thanks fellow leasmacruz.

Thank you, fellow Jard3162, I put the ic that you indicated to me and it worked perfect as I gave the assessment to another partner who helped me a lot. I also valued yours with a point. Greetings see you soon.
