No this capacitor is a non polarity capacitor it is only when you get into much larger size capacitors that polarity has to be observed these are known as elctrolytics |

yes you can, the trimmer is identified on the board as ct332 it is a small component and identified with a tiny slot adjuster on the top of this. You will be replacing this with a capacitor which is a different component but has two legs to solder through the board just as the trimmer.At maplins ask for a ceramic 15pf 50v capacitor it will just be pennies. Do make sure you are competant to solder and fit this component if not ask someone who is. Leave your TV off for a day before repair to make sure it has completely discharged.Good Luck |

Hi
I have just come across this forum. I am a retired brown goods tech and have been working for a rental company for 35 years. We also had a sony agency.You can forget all the other postings Gary,s posting is correct 100% ct332 was always the cause. Although it seemed like a dry joint fault it is actually a failure of the trimmer although we used to replace the trimmer I know that replacing it with a 15 pf will definatly cure this problem |
thanks very much for th reply
can i buy that CAP in the MAplins ? ( i don t know exactly what it is called)

DONT TWEAK THE TRIMMER JUST TAKE IT OUT AND REPLACE IT WITH A 15pf 50V CAP, I HAVE DONE MAYBE 40 OF THESE AND RELATED SETS AND NEVER HAD 1 COME BACK. |
