Toshiba 27WLT56B Dead No Power

[aar5384]

I was given another telly to have a poke around at, its nothing special and just something id let my mum have in her bedroom if it got fired back up again.

They guy who gave it me says the fuse in the plug blew, so he changed it and it worked for around 12 hours before being dead and now nothing happens at all when plugged in, no lights, no buzzing no nothing.

Ive taken it apart and its like looking into an old crt tv with boards and wires everywhere. However on the main power board 17PW15-8 the fuse is still intact, as is the fuse on the power cord board, but there is 4 bulging caps (C863, C806, C818 and C860)

Ive seen kits for other caps for sale but not these ones so i was wondering if anyone knows what other parts i should check ?

Ive marked the caps on the photo below with red arrows

Update.

Ive been a bit silly, I took it on the guys word he had changed the fuse in the power cord, im assuming that after it was on for 12 hours after the fuse first blew, and then blew again he took it out and didnt replace it, as just a quick thought to check the plug fuse, there wasnt one in there!

Popped in a 5amp plug fuse and it powered up! Picture is fine sounds working etc

So, i just see the issue of the bad caps that are top bulging now, should i just replace them or should i replace anything else as a matter of good measure?

Overall im feeling good now

Good fix - fuse eh!

You should replace at least any caps of the same make/series/value as those
that show signs of bulging.

You need to use low esr caps - Not from Maplins and some ebay outlets are a bit dodgy.
I think cpc.plc still have a no postage no min order offer on so currently suggesting Panasonic FR FM and FC in that order or nichicon or rubycon equivalents from there. Most times I notice you now have to order a min imum of 5 of each cap but should work out too much for a 27in tv

Sorry would have edited but you are on line so separate post
It is important to check the physical size as well as uf & voltage - we have seen people order caps that are to wide to fit.

CPC don't post dead tree catalogues. I've ordered from them and Farnell and never got any more than an order invoice in paper.

I've had one cpc catalogue in the year i've been ordering from them

if you continue to recieve them and crap from them, goto facebook or twitter and ask them to remove you from there mailing list

(I know some people mightent use facebook or twitter but it's the quickest and easiest way of asking questions with them)

Re: Toshiba 27WLT56B Dead No Power

I get about 4 or 5 a week already from them, everything from tools to computers to random junk, all go to the furnace anyway free fuel and free tv's

Just ordered them now, came to a massive £2.48 mix of Panasonic and Rubycon

got to admit tom been with cpc about 7 months now and have just received one magazine 148 pages on saturday from them very good offers in there in my opinion just offering last years slow selling items i guess.

Re: Toshiba 27WLT56B Dead No Power

I've never got one. I guess I'll keep an eye out for one, if I do find one it'll make some useful packaging material for posting off boards!

Well I turn down the HUGE catalogue 3600 pages or so as they used to send them by post and when your not in all you get is a postcard saying collect it 20 mile or so round trip.
Obviously doesnt say what it is - just a parcel so you trail out to get it.
HEHEHEHE Cpc is perhaps half a mile from my house!!

I do get the inserts and they can be quite useful as I often find they have a different catalogue number on the insert offers but if you search on line you just get to see the
full price item.

TRY this IP66 twin 13A socket
then try PL1156303
Bit naughty if you ask me.
