I have a:

Magnavox 27 inch TV

Model: 27MT3305/17
Chassis: L03 1U AA

There is about a 2 inch thick line at the top of the TV. It is a horizontal white line that is way brighter than the rest of the screen. Everything below it works fine. It usually cuts of people heads or any network logos etc.

It started about a week ago. I just turned it on one day and it started to happen. I don't believe it has got worse since the first day. Its consistent.

I don't know anything about TV repairs but i do run my own computer repair shop and I am willing to learn.

Can someone please help me please? After Christmas, it is not in my budget in the near future to purchase a new tv.

here is a picture:

C2465 10ufd 160volt

C2465 is the "location" number of the part in question; 10ufd is the "value" of the part in question; 160 volt is the "voltage rating" of the part in question.
Look on the main board, you'll see many parts, they each should have a location number stamped (silk screened - sometimes on top, sometimes on bottom, sometimes both) on the board. Match location number with part ratings.

So i would just take apart my tv, find the capacitor, solder if off and replace it with a new one, put it back together and tada?


And thank you JTS i just realized you were the same person on the other forum lol. I was wondering why 2 people posted the exact same sentence lol.

Working two threads on two different forums at the same time gets a little confusing sometimes. Laughing

That D6460 surface mount diode - anbody know where I can order one? Or even have some specs on it?

Found Cap 2463 but could not find the C2465 10uf 160volt capacitor on the main circuit board...What does it control and does anybody know where it is physically located???

Sorry about posting in the other thread.

Still need to find out if that C2463 on model 27mt3305/17 is the same as the C2465 everyone is talking about, because that Cap I have not been able to locate on the main circuit board...

Thanks for your help so far Very Happy
