TWF LCD 2641ID parts needed

[Jahson]

I've done a search first, TV at mates house didnt have cam so no pictures as yet.

The model is TWF LCD 2641ID, other numbers on the board TEP110ID &
05TA132C.

My problem is the a few compontents have blown to dust and just lef there legs.

1. Fuse blown 3.15amp location :>F300

2. IC21 one leg burnt & detached from FSD200 VG06

3. D201 blown to dust only legs standing

4. Cant see the marking on board thing its D200 or D300 only legs standing next to D201

5. C202 Ceramic Disc Capicator, very hard to read got burn marks only can make out ( KX222M ) on the top

I've seen a repair kit on that well popular auction site.

http://www.ebay.co.uk/itm/05TA0132D-...item23263ec692

Not sure if these are correct thought
D200 OR D300 =
D201 = BA159?
But the CDC its written wrong 2n2 2kv which i think is 2.2nf 2kv ?

Cant find the service manual or schematic, but looks like a few others use this psu board grundig, goodsman,bush.

I also just found out its a Sainsbury own brand

Would be greatful to ID the correct parts thank you inadvance

This seems more accurate http://www.ohmsupplies.co.uk/KIT05-R...0ID-/-TEP1101D

Amazing, same day and nearly same problem here. When I plug in the TV the standby led is red for about 5 secs, then silence.

My board is a 05TA132D / TEP110ID and you're right, my C202 is also 222M CS 560-2 565-1 Y400V and that's 2.2nF 400VAC. Here is the circuit plan for my board : h**p://arizanotlari.c*m/Semalar/Tv/lcd/telefunken/power/05ta132d-sema.pdf

Your point no. 4 seems to be the jumper cable J300. It's just a solid jumper, right between D201 and IC21.

When did your board blow up? On power-on?

Cheers,
Arnd

Re: TWF LCD 2641ID parts needed

Its my friends tv, happen like 2 months ago, only today ive been able to get around to have a look on it.

If i remember correctly J300 is next after that C202 & its just a jumper its a bit scorch but looks ok.

When i cleaned up the area it looks like legs from a components.
The one i couldnt ID it looks like i little grey blob or large ZD, the end had a large bit stuck to it.

If you can put up pictures, that help.

Re: TWF LCD 2641ID parts needed

Thanx for the schematic, im not that good at reading that stuff as yea, but will give it a bash.

Re: TWF LCD 2641ID parts needed

Hi,
D201 is a BYV36C diode.
I'll go to bed now but will upload a pic of my board tomorrow.

[Jahson]

Re: TWF LCD 2641ID parts needed

Many thanx tofubazille that D201 diode looks about correct

1. 3.15amp Fuse
2. IC21 = FSD200
3. D201 = BYV36C
4. ??? = Unknown part or jumper
5. C202 = 2.2 2kv CDC

And your saying (4) is a jumper

Hi, here's the pic.

Re: TWF LCD 2641ID parts needed

Thank you 100% yea on my friends board that area is complety burnt, cant read the markings, but thats is 100% correct.

Only different his CDC C202 is blue, and it blown his fuse also.

Re: TWF LCD 2641ID parts needed

Yeah, this area is just a bit "smoky" on my board. I really wonder why my TV doesn't work anymore. I will try to replace C202, D201 and IC21. -
I wouldn't buy these sets you mentioned, it's cheaper to buy in China (at least from Germany). I bought IC21 for 1,20€ on ebay (China) and the other stuff for some cents at a local store. Of course shipping will take about two or three weeks.

Re: TWF LCD 2641ID parts needed

can get on that well know auction site, that D201 = BYV36C thing the only part cant get on there.

Those kits too expensive £15 - 25 can get nearly every part twice for about £8

But from whot i can gather it looks like those 4-5 parts seems to be the problem.
Will also recommend a recap to him?

Re: TWF LCD 2641ID parts needed

I really wonder why all repair kits use a BA159 instead of BYV36C (like shown in schematics). They are both rectifiers but I don't know if they are compatible. - The weird thing is that C202 and D201 are connected to each other, on my board they are limited to 600V and 400V, the replacements are both 1000V and the cap has a different capacity.
So the question is: Did they use different components to improve the board layout or did they just use some components without thinking about it?
A BA159 would be much easier to get.

Someone around here with better knowledge and who can tell us more?

Re: TWF LCD 2641ID parts needed

C202, R204, D201 form Snubber circuits to protect the SMPS IC. Higher votage rating are better for this circuit. D201 has to be high speed switching type not general purpose due to power supply switching frequency. BA159 is a good sub since it has 1000V breakdown voltage.

That section of the power supply is the standby power supply which always running.
Did you get the new SMPS IC also?
is only rated at 600V.

Re: TWF LCD 2641ID parts needed

cheers budm so you thing getting BA159 is better than BYV36C, also you mention SMPS IC were about is that located on board? is it that IC20.

Re: TWF LCD 2641ID parts needed

budm, thanks a lot!!

I bought a new IC (FSD200) but I'm not sure if it will solve my problem (when I plug in the TV, the stand-by led is red for some seconds, then off).

Re: TWF LCD 2641ID parts needed

Check to see if you do have 5V at the 5V STBY PIN (Connector S300 PIN 6), it should be there the minute you plug the TV into the outlet.
@tofubazille, are the resistor, diode, cap in that snubber section checked out OK, if the snubber failed, it will take out you new IC due high spike voltage not being suppressed by the snubber circuits.
IC 21 is the SMPS IC.
IC 20 (6-PIN) is an OptoIsolator.
Cap C213, 33UF start up cap can cause problem also.
