Hello friends. I am fixing my TV that is left with a horizontal white line. The chassis is PSW29UTA-1B .. there is a burnt resistor, the R462 .. is 1 ohm 1/2 watt .. the problem is that in my town I have nowhere to buy components. I have several TVs that no longer work and I want to take a resistance from some but I don't get exactly the same one .. what other resistance could I place instead of that? on a TV I found 3 with the same colors (brown, black, gold, gold) but of a smaller size, can I put one of those?

Good day ... The resistance that you say is corresponds to the feeding of the vertical stage (+15) In this case by experience seeing the MAIN plate and not consulting the diagram, I repeat rather by experience, the resistances that go there are of 1 Ohms for 21-inch televisions and 0.68 Ohms for 29-inch televisions, all of them of metal film for 2 Watts, I repeat just the size of them ... For this reason if you have plates thrown there look for resistance They are in the same stages.

Hello, you have to get 1/2 or more because it is going to heat and it will not hold, but be aware that this resistance feeds the vertical, and it is surely damaged. Or you can associate with four girls of 1ohm two in series and join them in parallel is understood.

if it is less watts than the one it has, it will last less, because they take a temperature, or they will burn or increase the value and cause it to fail on the TV. One thing is the value and another the watts of each resistance.
