After suffering a change in the electrical network which blew the varistor 3505 and the fuse, it only turned on at 110vAfter changing the fuse and varistor, it was necessary to change the tea1506t (7520) to work on 220v.110909MAIRES

No plot and no soundThis TV had no plot and no sound. When activating the remote control, the LED responded normally. in the on position there was 126v at the tsh collector. It seemed like that classic defect of this model in which you just need to replace the transistors q7461 (bc337-25) and q7463 (bc327-25) plus the capacitor 2455 (47μfx25v). I was able to observe that only the bc337 was altered, but after replacing the three components the defect did not change. in the collector of q7461 it had 11v base 0v and emitter 0.3v. I started to suspect that the q7462 (pdtc143zt) could be the cause of there being no voltage at the base of the q7461, but as it is an SMD that is difficult to buy anywhere, I did some more tests and the defect was the q7460 (bu4508dx) completely shorted between base and emitter. Before, I had only tested between collector and emitter (where the short normally occurs). As I had a bu2725dx available I put it as a replacement. in place of q7461 I put 2sd667 and in place of q7463 I put 2sb647. An interesting detail is that the q7461 heats up much more than the q7463, which is why I put a small heatsink on it.

TV with sound, screen off, that is, no image.When doing the repair, I verified that the tube filament was lit, so that's when I released the screen wire from the tube plate, turned on the TV and measuring I didn't find voltage, it causes fly-back.The fly-back= at2079/b5 was replaced and it was... ok.Armando

TV didn't tune in to any channel, but the AV came on normallyThis TV gave me a bit of trouble but nothing that can't be resolved. The seletronic power supply tensions were all ok. I went as far as replacing it. But it didn't solve it. That's when I decided to check around the varicap. I went to the pin 4 and 5 of the seletronic and I had a surprise following the trail there are 2 100r smd resistors on them, they are written like this (101) because they were burnt outI replaced spark plugs and it was file, position r smd 3003, rsm 3004. pin 4 and 5 of seletronic scl sdaheliomar

No soundI had the 3.15 amp left output protection fuse burnt out. device.it only outputs sound on one channel if the good output is on the left side.in other words, on the ci7301, otherwise it does not output sound on one channel.In short, I inverted the output from the 7302 to the 7301 and replaced the output that was on the 7301 with a new one because it was shorted from pin12 to pin11, in this specific case it cannot measure on this pin.This email address is being protected from spambots.
