    5 As15 Ic Failures In A Week ! All With Different Symptoms

    Since last sunday I have received 5 Lcd Tvs all with odd screen distortions all caused by the As15 Ic gamma reference voltage Ic failing. All of the tvs showing different symptoms of failure. Heres what I have had:

    Samsung LE32M88BD Hd Lcd, screen had grey hazy boarder around any moving image. As15-F Ic voltage variating abnormally. Replaced and image perfect.

    Samsung LE32R73BD, washed out solarized/distorted image, after tv heated up solarization cleared. Found that gamma voltage started very low then raised, however all input voltage to As15 was normal indicating intermittent Ic failure. Replaced and Tv works fine.

    Samsung LE37M88BD, red distorted image with small columns spread across horizontal length of screen. Gamma voltage was 0v however input was normal, As15 was also abnormally warm. After replacing the Ic red distortion and small bars cleared up, however the was a line still out on the Lcd meaning it has failed.

    LG 37LH3000, total white screen no with faint image visible in background. As15 voltages at 0v input ok. Replaced image is perfect.

    Bush 42" HRT chassis with Auo screen, washed out image. As15 output 0v input ok. Replaced and tv works.

    Phew what a week or AS15 (F,H,G) failures ohh well at least I have mastered replacing these. Now time to sort the other 4 customer repairs that need looking at phew

    yes,these AS15F failures are nice easy money,had a Sony 32" that was completely blank-no pic at all,also a perfect pic but with image retention on a 42" techwood this week...other symptoms of the above.
    Heat destroys them very easily,Beware of buying the cheap ones from china-they tend to be out of spec-2 in 10 don't work at all!.
    A superior replacement is the RM5101,extremely reliable!

      Hmm thanks for the info will look into that Also very strange about the Techwood I have seen Lcd that have been stored for a while develop image retention but it clears after a while think they used AS15 gamma Ics too strange.

        I bought my previous 10 units of EC5575 (that's real AS15 part number!) at eBay:adeleparts2010 and all worked, no returns. I've bought 10 recently from another chinese seller (eBay:satisfyelectronics) but I haven't used them yet. Certainly, every time I buy a new batch I'm afraid of what I'll get.

        Interesting, RM5101 from Raydium. Never thought that an equivalent would exist. I can't find any datasheet, so I have to believe it.

          they are advertising job openings, maybe they should hire a guy to put the datasheets on the website!

            anybody buying an RM5101 - know what your ordering.
            during my datasheet hunt, i found they come in atleast 3 different packages.
