cyberlux tv does not turn on
Good evening: Always start the post by mentioning: Brand; Model and chassis if possible, but it is a very important fact. When mentioning components try to identify the stage that corresponds to said components and mention position number on the board for example: L420 / L415 and so on ... It may have a short in the horizontal stage, it may be the transistor Horizontal output Etc ... Improve the post ...
friend check the diodes at the output of the choper also check the horizontal transistor plus b
Take out the transistor and it is short on all 3 legs I will replace it. A question if I put it again could burn again.
friend check your more b place a 100w ball between collector and emitter and test the source that is not elevated comment
Solve all the tracks had many cold welds change the horizontal and already turned on. But the cushion effect remains a fault. Q I recommend checking, it will be the coil that suffered some damage. Since when I first saw it the track where the coil is going had exploded.
Friend that's right, it's because of the coil, I recommend looking for an identifier and if the fault continues, check the flay-back.
The flay back that it has is an adapted one, it shows why they cut tracks and there are adaptations I have one from another board the same, it will be that I will see how it works. why there are resistances that do not go where they have to go originally
Please I need the diagram of this tv the board is a jug7.820.437 2008.07.07 needed to locate some resistances that are loose
It is the same one that needed to locate some resistance to place them where they go and the flay back that I had was adapted and I am placing an original one but there are pieces that do not go where they have to go
Hi, I tell you to change the flay back to an original one from another board. put the resistors in place, but turning it on works with distortion I give the flay back knob to accommodate this distortion and does not accommodate. It remains the same, apart from the red wire that comes out of the flay back towards the plate of the desoldering tube because it will happen that it welded it and it takes off again
Friend also got another detail. When I turn it on after 10 minutes the screen turns off. The tv is still on. And it is heard. .. I turn it off and on again and it works normal and the Arctic turns off again.
friend. change that bovine for an equal and if the tv. keep doing the same thing change the small filters of the source and solve the choper and flayback pins as I indicated there arrives but this is when the cushion failure is already solved
Someone has a diagram of this board that I am going to place an original flay back of this TV to replace the one that is already in place since it is an adapted one and I need to know where the resistors are going since they modified several things the board is E198946 is a cyberlux tv twenty"
