bauer xt 32

[eddolls]

Hello people, 
I have just purchased a faulty Bauer xt32 with the common psu fault where the fsd210 IC blows.
I bought the basic ohm supplies kit to replace the faulty components. but I have noticed that the component L501 is fried, which doesn't seem to come with any of the kits and I have no idea what it is??? the service manual or any circuit diagrams seem to be unobtainable, so I am asking would any of you cleaver people on this forum have any ideas what this component is and where to get it from.
Any help greatly appreciated.

Hello eddolls

Done several, but don't recognise L501 - perhaps a piccy might be useful - Chris.

Thanks for the quick reply, I have circled on the piccy it looks like to diodes stuck together. The board looked burnt round that area and when I removed this strange little thing it fell apart.

hi
l501 looks ok what about the diodes and ic
they are burned out have you fitted the kit

Hi,

Just checked on a spare panel and L501 is just a wire link with a pair of ferrite beads. Notice it's on the drain of Q501 feeding T3 (24v supply transformer, perhaps) so might be a high pulsy current dry as in scan coil connectors of old.

All the best - Chris.;

I did think they looked like ferrite beads but I wasn’t sure. I could just stick them back in as long as they arnt open cct.
I have another question now if that’s ok . when I received my ohm supplies kit it said to check the transformer by the fsd210 primary side for a short and if there is repair it? I have never heard of repairing transformers before especially ones that small!  So checked it and there is one, typical.
 I emailed ohm supplies to see if they could supply me a new one and they said no you have to repair it yourself.
What do you think I should do??
 I have worked in the electronics industry for a while but I am not that experienced in TVs to be honest, still electronics is electronics and I am sure I will get there if i persevere.

once again all your advice is greatly appropriated.

regards

chris

Hi eddolls,

Thought is, that with chip demise, S/by tranny itself might  have problems (check profilo) if you enjoy pain, but that's Profilo, and they're not a nice telly.

Never had such suggestions with this PS, and never had a S/by prob after chip and bits  replaced, so what's trouble after your possible dry joint 24v area - Curious - Chris.

I think I am just being over careful and scared of plugging it all back together only to get big bang. I am going to plug it back together and firstly hide for cover and then check for voltages. maybe stiff drink first. if it doesn't work I suppose I can always buy a new board

Hi guys,

Id thought I would update every one on my progress with repairing my Bauer xt32.
last night I finished installing the 06 kit from ohm supplies including the smoothing cap. I then repaired a few blown tracks with wire, and resolderd dry joints on the ferrite beaded link and a couple of inductors on the rectifier stage.
This morning I rechecked my work and refitted it to the TV, with great anticipation I powered it on (half expecting my careful work to go up in smoke). It didn't! The set powered on , I had sound and all the inputs worked!
  

Thanks everyone!

Regards

Chris

Hi Edd,

Congrats, glad it wasn't a Profilo - Chris.
