42PJ350 clicking noise

Re: 42PJ350 clicking noise

There's something like 20 of them! Which ones in particular?
You can read resistor colour codes right? If not:
https://www.google.co.uk/search?q=re...or+colour+code

Very, very rare for resistors to fail shorted (considered unsafe, they are designed to fail open circuit.) Note, some resistors can be very low resistances, sub 1 ohm that does not make them bad.

Thank you
Tom

found 6 components short ysus board, ey712,ey710,ey714,ey752,possible ey736 all fets, 2 diode open d712 d713
checked the buffer board no shorts. tryed unplugging the buffer turn on still clicked there another way to make sure?



going to try and order them today do they have to be exact the same hard to see some of the numbers?

Re: 42PJ350 clicking noise

Hi
Found these igbt off a samsung board x-main board 30F123 what would like to know compatable, need 30F124 ?

look exactly same just different number on the end

hope someone can help

Theres a ysus here for sale

Hi just confirming ysus board that is faulty,going to have a go fixingfaulty componentsif any one knows repair kit great help
thanks again guys awsum site.

Re: 42PJ350 clicking noise

Hi
does any one know where i can buy these green coated resistors having trouble finding them from the uk
cheers

Re: 42PJ350 clicking noise

Hi Where can i find these green coated resistors can only find them with blue coating, still ok to use ?
same colour band as the green just want to make sure

Re: 42PJ350 clicking noise

You can use any colour body... the bands are what matters... but why are you replacing them? Resistors rarely fail without obvious marks such as burn marks or discolouration.

Your fault looks like Z-sustain fault.

Re: 42PJ350 clicking noise

2 are short 1 measures to high
Definitely ysus board mate.

Thank you Tom for your information i will order them now

Re: 42PJ350 clicking noise

I've said it before. Resistors nearly never fail short (they almost always fail open), and you can get low resistance resistors. Yours are 2.2 ohm, so that is fine, for them to show shorted on a simple multimeter.

I really doubt they will do anything for your problem...

Re: 42PJ350 clicking noise

Ok they Failed open was suppose to say sorry!
2x 30j124
2x 30f124
faulty all on the ysus board, Have you fixed ysus board Tom on the 42pj350 Model of the board EAX61332701 can not find repair kit.

Re: 42PJ350 clicking noise

What are the colour bands on them and what do they measure each

[marty-clubber]

Re: 42PJ350 clicking noise

Red red gold gold
04.7
04.2
3.47
cheers

[tom66]

Re: 42PJ350 clicking noise

Red-Red-Gol-Gol = They would be expected to measure about 2.2 ohm each.

So... assuming those are all on the 200 ohm range, you are getting 4.7, 4.2 and 3.5 ohm each, but those sound acceptable, considering tolerance of the resistor (5%), meter (2%), and by far the most significant effect, the zero-resistance of your meter.

To measure the zero resistance of your meter, set your meter to the normal ohms range, and touch the leads together, what do you measure? I expect around 1-3 ohms for most cheap meters.

Re: 42PJ350 clicking noise

Ok, different tact... Try probing across a lead of one of the resistors (so red probe and black probe on same lead just to short them out.)

[marty-clubber]

Re: 42PJ350 clicking noise

03.7
03.9
4.85
after shorting them out mate

[tom66]

Re: 42PJ350 clicking noise

Eh... Just to be sure, both probes on the SAME lead of the resistor, this is just to test how well your meter probes against a resistor (contact pressure affects resistance, especially at low readings...)
