Haier HLH376bb not powering on opened to find issues

[tozzzy]

Hi all

any help you can point my way is much appreciated

so I have a Haier HLH376bb with powering on issues I have opened it and found a bad cap and in the removal process as it was glued down with the white glue I also broke a resistor which was right above it on the board me and my fat fingers

I have already got the service manual for this set but I'm not really clued up enough to understand it yet and my main questions what replacement cap and resistor do I need I looked on digikey and trying to work out the right parts completely lost me as they have about 7 or 8 pull down menus asking for info that I don't know

I have attached pics of the bad cap and the resistor and the board and uploaded the manual for anyone that can help me out

once again thanks everyone for any help you can give me

the resistor is R41 on the board and the cap is C32

Re: Haier HLH376bb not powering on opened to find issues

The resistor is 0.22 Ohm MOX (Metal Oxide) type, 1/2 Watts. You should measure the resistance, it may be OK, you have just scratched off the coating but did not damage it.

Re: Haier HLH376bb not powering on opened to find issues

However, the coating forms part of the flameproofing, so would be best to replace for long term safety and to prevent further damage in case of failure.

If you make an order with Digikey you can get both at once:

(Cap -- looks OK -- check dimensions)

Tom, Good job finding all the parts on Digikey.

Re: Haier HLH376bb not powering on opened to find issues

For the cap, I just searched 150uF 400V in Digikey, selected the first one with leads from a respectable brand. No narrowing it down - Digikey website found only the caps matching my search. For the resistor I searched something similar to 0.22 ohm and this was one of the first results...

Wow thanks to the both of you for your help in tracking down the right parts just ordered them from digikey once I receive them next week and there installed I'll post an update hopefully all will being working placing this Lcd as number two that I've repaired

Re: Haier HLH376bb not powering on opened to find issues

Did you check that capacitor before you ordered would fit?

Yep the one you found was slightly longer but there is space below so hopefully all will be well

hi tom66

so just got the parts back from digikey the capacitor is spot on but the resistor you found is completely different as you can see in the pic's below not that I'm complaining because its no big deal as they were only a few cents would you be able to find the right one Ive tried looking but again but I am still a bit confused with selecting the right resistor and also they may of just sent me the wrong part if so I can send them and email I've added some measurements to the pics this time to help in finding the right size

the color bands on the old resistor are red red silver gold
and the new are red red silver gold white

once again thanks for the info and any help you can give

dear
Original register is 1/2 watt but new register is 1/4 watt so please find 0.22 ohm 1/2 register

Use the Digikey search box. I am not an automated ordering system.
