Samsung 226BW flickers for a few minutes when powering on - Page 6

post #51 of 114
Compliments and a HUGE THANK YOU to "Dricks" for a great instructional. Using your detailed guide I was able to repair my Samsung 226BW to exceptional condition. As a techy-hack and retired professional musician. I had plenty of soldering experience fixing bass enclosures and amps in emergencies. I purchased the Panasonic caps from "Digi-Key" online. Using the larger capacity as suggested. Installation was a breeze. The only minor hitch was that Digi-Key is a high volume distributor and there is a minimum $$ amount of about $25.00 for them to bother doing a transaction with you. So I ended up buying some screen cleaner and DVD drive cleaner to beef up the order. They were incredibly fast with delivery.


My SyncMaster 22" had begun the flickering stint at start up some time ago. At first for about three minutes, then three became ten, ten became twenty, then hours before it would correct itself. I did take another bloggers advice and dim the brightness to minimum. It helped for a while, but what eyestrain trying to read text. After CAD designing all day at work, already eye fatigued, my home monitor totally burnt me out. All is well now, and it's time for me to buy a new video card to optimize the monitor's potential.

Thank you again Dricks!

Hopefully by now (*IF* we've ALL got the same problem w identical model number monitor {which I strongly believe!}) most of us learned the flicker only "starts off" brief but learned the period gradually increases to where mine is now at 30min & I have no reason to doubt it'll only get worse & worse until ONE DAY "Totally intolerable & soon UN-watchable.

This HAS TO BE 1 OF SAMSUNG'S (supposed to stay 'eternally secret' "Learning Experiences" that they WILL NEVER ADMIT TO! If we didn't ALL have identical problems with the identical model number--I WOULD NOT SAY IT! The facts are -here- for Samsung Techs & Brass to dream up excuses for phone techs to force buyers to swallow---whether they WANT TO or NOT. That should do WONDERS for Samsung's reputation! mad.gif

Same here - I resurrected my monitor using the detailed and precise instructions.

I too needed to add to the order but ended up with a torch-screwdriver that is essential for failing aging eyes! I am doubly better off!

dricks-

Many thanks for posting this procedure. All was as you described, including the bulging caps. I decided that it was a good idea to up the voltage rating. I was able to get 35v for the 1000mF units, and 50v for the 330mF. I have heard stories of power supply capacitor failure when they were run too close to their ratings, though some of those failures involved not only smoke, but flame.. Fortunately, this was not so violent.

Thanks again! I signed up with overclock.net just to say.

Much props to Dricks!!!!

I have a 226BW that started to flicker a few weeks ago and found this thread. Followed the step by step disassembly pics and found 5 bulging caps from the power supply board then I found a kit with 6 caps, solder, and solder wick from lcdalternatives.com for $12. After 1/2 an hour I have a monitor that works like new!!!!!

Thanks!!!

I also got the kit from lcdalternatives.com, and a 25watt Weller iron, and using dricks' guide my Samsung SyncMaster 226BW is back from the dead.

It was my first time soldering anything; the only trouble I had was that the solder wick (braided copper colored stuff in the kit which is supposed to soak up melted solder when you're removing the old components) didn't seem to work very well, and the iron's heat application felt very hit or miss -- I'd press it against the joint for 5 or 6 seconds and nothing would happen, and then I'd shift it just a millimeter and all of a sudden the solder melts right away.

Anyway, thanks dricks for your awesome guide and pictures.

I appreciate tou trying to help, but when I spend this much $ on a monitor, and it works just under 2 years & starts this flickering that I'vve seen last 8-24+ hrs before it stops--the LAST thing I want to read is someone saying "Sounds like it's Dying alright". Sure I'll agree, but this is NOT why I spent the $. Right now I could KICK *SAMSUNG'S* Ass!! smile.gifmad.gifmad.gifmad.gif
