Tevion LCD 4040 main capacitor failure

[divy]

hi i have tevoin lcd 4040 tv aftar i install some capasiter then tv work 1day then my big capasiter blown but i dont undurstand big capasiter 220uf 450vdc i dont find vdc capassiter can i put 220uf 450v capasiter?

Re: Capacitor Identification

What different 220uf 450v cap between 220uf 450vdc cap?

i think you can use either as same uf rating and voltage.

Re: Capacitor Identification

Thank for replay after I install 220uf 450v cap now it fuse blown why is it

did you check you have got the polarity of the capacitor rite when you soldered it in also what are you working on a tv? make and model may help us.

Re: Tevion LCD 4040 main capacitor failure

I'd agree with Vinceroger69 that you may well have had it in incorrectly. Are there any markings on the capacitor indicating polarity ie is there a "-" or a "+" on the casing? Can't tell from the picture.

Can you also post a photo of where it should be soldered in the power supply.

Some more pic power supply .I think cap it wrong I have install 220uf 450v

Re: Tevion LCD 4040 main capacitor failure

in picture 2 if you have installed the capacitor as shown with the negative band on the left it should be ok what was the original fault with this psu? as i have repaired two and never had too change that capacitor start by testing the bridge rectifier then all the devices that are on the heat sinks for shorts.

Re: Tevion LCD 4040 main capacitor failure

Thank for replay. First I have change some caps form power supply then TV work for 1day next day TV work 1hour then big caps blown and fuse gone and more problems started I have change big220uf 450v capas come out form power supply 220uf 450vdc something do with vdc capas I don't no how chack sink shorts please help me out

Re: Tevion LCD 4040 main capacitor failure

whats the power supply board numbers i think we need to find a schematic first.

Re: Tevion LCD 4040 main capacitor failure

Fsp273-4f01 - rev:1 capas OK that I have use or I have change to vdc capas

Re: Tevion LCD 4040 main capacitor failure

ive just re read the thread i posted ages ago when i was working on a faulty set there are no schematics available for this psu all i can suggest is double check all the new capacitors you have replaced are the correct voltage and uf rating ( the same as you removed) also double check you have fitted them the correct polarity into the psu.

Can I buy this capa https://m.ebay.co.uk/itm/CAP-ALU-ELE...MAL215747221E3

Re: Tevion LCD 4040 main capacitor failure

did the original one blow up without encouragement ?

Re: Tevion LCD 4040 main capacitor failure

After I changed some capas original big capas blown

[vinceroger69]

Re: Tevion LCD 4040 main capacitor failure

i think you may of put a capacitor in the wrong polarity or the wrong voltage rating or maybe a bridged solder joint so double check all your work. i have had another look today and cant seem too find a schematic.

Re: Tevion LCD 4040 main capacitor failure

I have chack everything all OK what you think because big capas not vdc that's why fuse blown
