    How to Test EN220A and E220B IC's

    I have a Sanyo DP42841-06 TV that won't turn on and I was trying to trouble shoot power supply. The only chips I was not getting ~.45V on when measuring in diode mode were the EN220A and E220B chips. I got ~.221V from C->B and C->E on both. I don't know if that is to be expected or if they are bad. I'm not getting a short across them.

    Also, if anyone can tell me where those two chips go on the board, I forgot to write down where they came from as I'm a noob.

    Thanks!

      Best place to source RAM chips? 8GB 820-00850 boards to 16GB or 32GB
      by ugamazing
      I'm looking to upgrade several 8GB 820-00850 boards to 16GB or 32GB for personal use. I am curious what the best practice and process is for sourcing new replacement chips, and what vendor(s) you guys prefer? Another question is, how do I find compatible chips and their corresponding part/model numbers? For example, in the 820-00850 schematic, the DDR chip U2600 model listed (EDFB232A1MA) corresponds to 1x32GB chip. Of course, I would need 4x8GB chips to replace the 4x2GB chips currently on the board. How do I find compatible 8GB chips? Is it as simple as searching "BGA178 8GB 2133"...

      How Can I test PWM DM0365R?
      by chth96
      Hello
      I have power adaptor(220V/input, 12V 1.2A/output) which has symptom of fluctuating output DC voltage between 11.5V-12.2V.
      So I opened its plastic case and when switched it on, I heard constant tik tik sound from inside its PCB.
      I measured DC voltage between negative and positive pin of the largest capacitor(400v 10uf) and it was measured contant 300V.
      I also measured ESR value of all capacitors and I noticed that one of capacitor(KMG 16v 470uf), which located in the secondary side, have high ESR value(10 ohm),So I replaced it with same specification NXH capacitor....

      WSON8 NEW Bios Chips READ, ERROR, ETC.
      by feherhollo
      Hi,
      I asking for help on some new WSON8 256MB chips. Please share your experience. I faced error on some new chips on read, erase, write with different programmers. These new chips are not exist in any programmers database. (GD25B256D, XM25RH256, W25Q256JV so on.)
      I'm using RT809F V.5.0, EZP2023 Pro, CH341A Green

      For the exact experience with GD25B256DYIG is RT809F erase the chip under 33sec. This kind of 256MB chip normal erase time is 70-120sec so I think not all the partitions are erased. If I do blank check or reread the buffer says FFFFFF but when I write the correct...

      test active pfc power with lamp test
      by khelane
      Hello
      I have a big problem and that is that in some cases when repairing active pfc power supplies I cannot work with a test lamp. I can only get help with 5 volts standby and for starting and starting I have to work without a lamp and this way there is a possibility of parts exploding and other parts being added.
      Sometimes with a multimeter test the problems can be reduced to some extent, but I had several cases that had to be tested on and online and recently two varistors exploded. They had terrible resistance because the power supplies were over 800 watts.
      Is there a way...

      Mats / mods: detected and repaired GPU fault. Cant seem to test after!
      by chronic519
      Hello.

      GPU came in, green lines. Spent lots of time using to get the Mats / mods drive working (found on youtube).
      Found issue with a RAM block
      Replaced, green lines gone.
      Trying to test again, assuming getting the false positive. Originally had over 1K on a single bank. Now getting tosses low between banks.
      Used a good card to test and same results low errors 32+.

      I am just search for some form of command to do a full test on the GPU.
      I just ran the mats command with my good GPU and passed after roughly 40 min.
      The repaired one, ran...
