Watching here idol ang galing naman great skills thank you for sharing
Ti rignrazio tantissimo, TV aggiustata con 4 euro. Grazie di cuore!
im glad you fixed it my friend.it would be wastefull to throw it away for just one capacitor.
hi i have a philips crt tv after a few seconds is shutting down can you suggest me something ?
look for 22uf capacitors 160v or 250v and check if they are swollen or leaked.and replace them.at the time the tv is turning on does horizontal-diagonal lines appear on screen?
@@electronics4allno sir i havent notice horizontal lines just this its shutting down after few seconds its turn on thanks for your answer i will check it
I got one at Goodwill for ten dollars. Works great!
I’m so thankful you posted this. Same TV. Exactly the same issue. Had to buy 6 of the capacitors at $12/CAD, $2 each. Used one, TV works now, and I look competent :-). Thanks for really making my day.
I had the same problem, same solution at the price of less than 1 euro, thanks a lot
Samsung made it like this on purpose they want u to buy or repair it for them scam very disappointed cost me £800 only had it 2 years now this !
The TV was repaired, but 20 days later the problem reappeared. Can you help me, what else must be wrong? Thank you
it depends.which components did you replace?is the problem exactly the same?i would test or replace the other electrolytics also.
@@electronics4all Just replace the electrolytic (680mF/16V) that you show in the video. It worked perfectly but after 20 days or so, the TV came back with the same error. Yes, the error I have is exactly the same. Thanks for your response and help.
@@electronics4all Can you help me please?
@@gabrielbermudez7392 you should make some measurements.what voltages are on the power supply and what voltages are at the output of it,measure the esr of electrolytic capacitors or replace them if you dont have esr meter,measure resistors,diodes,smd components,there is no magic solution.each case might be different..
great !! 💫

one question are LED bars from alliexpress any good ? guy in tv service told me they are not good and they broke after few months?
i dont really know.i buy them from local dealers in greece.
Para eso mejor miro Charles Chaplin, que también es cine mudo.
I have a bulged capacitor too the exact same one but for me the power button doesn’t even blink when I tap it. No remote just the panel. Could this be related?
I changed IC , transistor , 100pf capacitor and 0.33 ohm resistor power supply working but noise coming there how can fix noise?
congratulations, very good work.
καλησπερα φιλε,συνεχισε την καλη δουλεια...εχω το ιδιο τροφοδοτικο.αφου αλλαξα την ασφαλειοαντισταση,τον πυκνωτη που εσκασε,το μοσφετ,το pwm καθως κ μια ζενερ, στους μεγαλους πυκνωτες εχω κανονικα τα 320V οταν τροφοδοτω την πλακετα.οταν ομως αποσυνδεω τα 230V της τροφοδοσιας οι πυκνωτες εκφορτιζονται μεχρι τα 90V κ μετα δεν εκφορτιζονται αλλο.στην εξοδο εχω κανονικα 12V.τι μπορει να φταιει?Σε ευχαριστω εκ των προτερων
i have the same monitor with the same problem. can you please tell me where i can find you so i can bring it to you an repair my tv too?
More China junk, thanks for the video
can it give stable 3.3V voltage when input is at 250mA and 3.7V
Hi! I need help with my Philips crt model 14pt1353/00 that has the chassis L6.1 AA too. The TV works pretty well but the horizontal width of the image is a bit wide. Do you know how to solve this problem?
Maybe an electrolytic capacitor close to that circuit. Or else settings from service menu.you have to google it how.
thanks a lot, I am going to try it🤓
you're welcome
good project but this is not electronic microscope - it is an optical-digital magnification device.
yes i know.lost in the translation
Hi, I have an old Dynacord system, one of the F-150 Speaker is playing up, Not sure what the issue is, maybe the crossover board. Speaker unit is getting power, tweeter is working, but nothing going to the main cone. Any recommendations to fix? Thanks
sorry for the late answer.if there isnt the speaker it self you can test it with a multimeter or a small battery to see if it is working.or else it may be the crossover pcb.
Excellent video; well produced. Convinced me to not toss out my T22B350 (US model) TV. I've repaired a couple of Samsung SyncMaster PC monitors (just control panel replacement); I can probably at least recap the power supply on the failing TV.
I think with me its the Fuse, but I cant find a replacement anywhere
the fuse never blows without a reason.unless there was a power surge and the movs of the power supply protected the psu and burnt only the fuse but this is rare.in any case replace the fuse with the same rating otherwise you may damage further the device if there is a short somewhere.
Is Arduino Pro Mini + USB in TTL used, on the diagram it says that Arduino UNO ???
it doesnt really matter as long as you connect the correct pins.you may use uno,nano,or pro mini at 16mhz
thank you@@electronics4all
if you are interested to build a good soldering station i would recomend this one. oshwlab.com/wagiminator/z-solderingstation-smd-v2 the one you are talking about is very old project and not very accurate in temperature reading.of course im still using it until today without problems but the one im suggesting is even better and heats up in 10 seconds. i helped the author of this project for some improvements in software and functionality and he is very kind and helps in everything you need help. .
do leds from like aliexpress work?
Hello! Could you tell me what value has the ntc sensor? Thank you!
Just came to say that I had the problem with the push not selecting track. Upon desoldering the encoder, one of the pads (bottom right) for the push function fell off with the solder so the encoder itself was fine but due to getting pushed a lot and strong, the pad on PCB just had teared off. Little jumper on the PCB and now it's working again.
yes.a common issue also.
@@electronics4all thanks for your video, it encouraged to fix it.
waste of watching, not shown the connections of camera and tv
What connections you want to see?.its a usb camera-web cam.if you watch the video it says so.you take the camera module as is with its cable and plug it to a usb port.
Εγώ βρήκα τον μπλε πυκνωτή σκασμένο. Τον άλλαξα αλλά τπτ. Που μπορώ να βρω το πλήρες σετ επισκευής που αναφέρεις? Υπάρχει κάποιο λινκ; Ευχαριστώ

Anybòy knows what kind of crossovers these?
Thank you very much for the circuit. I can deduce from the images that the first switch is for powering the circuit, the second current selector and next to it the dc output potentiometer, but... and the last toggle switch, what is it for?
it is for 3v output or higher.the circuit cant provide 3 volt by itself so the switch connects the output to a 3v regulator.
Ευχαριστώ!
να'σαι καλά..
I opened my monitor and capacitors looks fine, but the monitor just work for 3-4 min and shut down. If i disconnect the cable from main boad i got a white blink from backlight. I dont know what is the problem here. Any idea?
Muito Obrigado , Excelente explicação.
thank you..
Goodddd
I have the full system and just fixed the drawer. I wish you had shown the mechanism that keeps flip down control panel up. Mine will not stay up.
Μου χάρισαν μια lg έχει το ίδιο πρόβλημα πόσο θα κοστίσει η επισκευή; Αν είστε στ Αθήνα να επικοινωνήσετε μαζί μου ευχαριστώ

Have a nice day. Your help is awesome, thank a lot. By the way, 0.33 Ωμ is an ordinary resistor, because in your photos some are cylindrical an some rectagular. kind regaeds Stavros
ευχαριστω φιλε μου.νασαι καλα.
@@electronics4all η 0,33 Ωμ ειναι κοινή αντισταση ανθρακα 1 watt ; γιατι δεν βρισκω τον τυπο που φαινεται ως κυλινδρικο εξαρτημα. σταυρος
@@stalopix μια οποιαδηποτε αντισταση 0.33 ohm 1~2 watt. αλλιως αν δε βρισκεις τετοια βαλε 3 αντιστασεις 1 ohm παραλληλα που ειναι πολυ πιο ευκολες να τις προμηθευτεις.
I plan on making one of these. Ordered the pcb and parts. I still need a T12 handle/tips/plug. I see a ton of them on Aliexpress, Does anyone have a recommendation for these? They all sort of look the same, I just want to get a decent handle with a few tips and the (4-5) pin plug for the handle. Thanks.
the handle itself isnt gonna fail.on my handle the socket of the handle starts to lose contact sometimes and doesnt recognize the soldering tips after about 2-3 years.you have to rotate the tip to make good contact.for the price i bought it im not complaining.with some contact cleaner or tightening the contacts might fix it.thankfully i have more handles if this one fails completely.
@@electronics4all Thank you. I seen some handles were aluminum, but much more expensive. If the plastic ones work okay, then I will go the cheap route (That is what this project is all about anyway). :D
@@electronics4all I was looking at the BOM file and JLBPCB did not have all the components in stock. I was going to source them elsewhere but there seems to be an issue with the Zener diodes. One is rated 5.1v and the other 18v, but they both have the same part # in EasyEDA. Anyone else have this issue?
Muy bueno. Lo que no entieno si todos los reguladores 1117 son ajustables variando el ajuste puedo tener 1.8 3.3 5 vols con solo variar el ajuste muy interesante tu video
not all lm1117 are adjustable.if there is a marking ''-adj'' on the case then it is adjustable..
music sucks
Nice fix thanks
you're welcome.
How do you open the monitor? I unscrewed the bottom part of the panel, but I cant remove the case
everything is with plastic clips.you have to seperate the cover with a screwdriver carefully..
Do you have a video or can you link to something that shows opening the case?
Chinese version of that is fake. They cannot able to provide 3.3v output. Incontrast of what stated in the datasheet
i know most of the chinese semiconductors are fake or it doesnt met the specs..
Obrigado E nois 👍
thanks.
What are other alternatives to this, we got this, but since our usage is like at 90% of rated load, it's getting very hot.
Hi can you make a text to mention which pins on the lm358 is connect to which pin im confused by the marking in the schematic can you help me please :)
