Hi everyone. Now I come to share the repair I made on this tv I hope it helps someone in the future. here the link to download it http://www.mediafire.com/file/30swzdlz42zb5yl/panasonic_ct-20g11u_chassis_amedp269.pdf This TV when connecting and giving the power order, the click of the reley was heard and a noise was heard, then I went to the source and found a short circuit measuring with the TV disconnected and downloading the main filter of the source C801 of 330uf that It is before the transistor Q803 FN521 with the multimeter in the diode scale and in that filter there was a short but it was not tested by the filter since I took it out and the short was not removed so I removed the transistor Q801 and said short was removed. but even so I also went to the horizontal output transistor to rule out problems and I also found it damaged so I removed it without putting it back on, and connected the source to the series to verify voltages over the entire B + 130 without finding it. so I started to overflow the source again and found the R801 2.7 ohms for 7w open and change it and test the source again connecting it to the network but without putting the Horizontal transistor and this time if I found the B + a little high but since I had no charge for not having the HOT it was logical. so I put a fake load with a 60w focus in parallel on the C809 capacitor of 33uf 160v and this light turned on and measured voltage and was a little low but within the parameters. I proceeded to place the horizontal transistor and interrupted the B + line to now put the focus in series to avoid damage to the horizontal transistor and the tansistor that changes the source in the case that there was some other fault in the horizontal stage. I connected the TV I gave it power on with the screen a bit accelerated but I just adjusted it and my image well. and let it work for a few minutes and disconnect it and touch the transistor heatsinks of the source and the horizontal and they were not hot so I removed the focus of the series and tried again and everything was fine. With that I finished the repair. I hope you find this experience useful.

Hello friend and colleague. amilcar thanks for your input sele thanks and will be noted in my notes and for other colleagues who have that fault on a tv. of that brand and others a greeting.
