Re: Philips BDL3231



Of course i'm going to replace caps, i just hoped my original efforts was enough.
Do you mean replacing all the small caps on the main baord too or just in the psu+inverterboard? There are about 50 caps on the main board......

What happened next? everything ok?

The diodes in question are actually connected in series, but are they broken?

If i did recap the whole PSU and Inverterboard, what are my chances that the tv will function fine? until i saw the diodes i thought it would work with just the caps, but now i wonder what more could have gone bad...

i have the schematic if you are interested... page 17



The inverter board is not in there, but there is no visible damage at all except for the...

Re: Philips BDL3231

found two badly burned diodes on the primary side, is this a bad or common thing?...

Re: Philips BDL3231

I realise that reusing caps is not at all recommended, but i don't like spending money if i don't know it it will help. Should i replace all caps everywhere i go by your approach?
Also i don't think digikey distibutes to sweden, i have elfa.se though, they seem to have a lot of caps.

Some pictures after my initial atempts.
Do you need pictures of the main board aswell?...

I recently got a trashed LCD panel from work and it was broken (surprise!)
It does turn on, then it chirps and turns off, restarts again and so on (about once per second).
So i took it apart expecting bad caps, and this is what i found:
1. 1200uF 35V 105C CapXon x2
2. 2200uF 16V 105C CapXon x1
3. 680uF 35V 105C Capxon x2
that was obviously bulging and broken.
I have "replaced" them with some scrap i found, but it still chirps and won't stay on for more than half a second. With "replaced" i mean:
1. 1000uF 35V 85C Nichicon...
