Question about Haier 42EP24S 42 in. EDTV-Ready Plasma Television

TV-3940-01 upgrade kit ordered. What about power supplies?

My Haier 42EP24S seems to have the same problem with sound but no picture. I noticed someone had posted that the unit has 2 power supplies. One for video and another for audio. I have the upgrade kit coming. Could it be possible the video power supply is the issue? Sears was no help and Haier was no help. Just the run around from both when contacted. Last $ of mine they'll get!

    The parts were ordered from Hair America at 1-877-337-3639 which they still have on back order. Searching Ebay I found a guy in New York that had the complete kit, contacted him and he sold it to me very cheap. He got tired of waiting for his parts, took the TV back and bought an LCD. Then the Kit came in. I have the complete service manual, Upgrade kit installation instructions which I've put in PDF format in case anyone needs them. Good luck! It's taken me months. Parts came today. Once installed I'll post the results.

    If anyone needs the install instructions with photos for TV-3940-01 upgrade kit (Haier 42EP24S) which is 4 pages I have them in PDF format. I also have the complete tech service manual in PDF format which is 50 pages. You'll definately need the upgrade kit instructions, there's a sequence you have to go through with the remote to update it. Drop me a line with your email address and I'll forward them to you.

    Upgrade kit TV-3940-01 installed and TV is working better than ever before. Prior to installing the boards and eprom I decided ohm the boards and found the fuse on Control board TV-5210-37 blown. I replaced the fuse, TV powered up and worked without issues for the next 22 hours straight. Since I had the upgrade kit I installed it. Until you can obtain the upgrade kit (which seems to be hard to get) you may want to replace the fuse. At least you will be able to use the TV until the kit is available. If I can help with any questions let me know.

1. Disconnect power to the unit.
2. Remove the rear access panel by taking out ten screws, 5 across the top and 5 across
the bottom. Use care when handling the cables connected to the power switch, so they
are not weakened during this handling.

3. Locate 1C #1110 on the digital board, carefully remove it from the 1C socket and replace it
with the new 1C. Note: Be sure to take precautions to avoid electrostatic discharges,
which could damage the new 1C.

4. Once the new 1C is installed, re-attach the rear access panel and apply power to the
5. Turn on the monitor with the remote.

7. Using the Volume button (Remote or Monitor) turn the volume all the way down.
8. Hold the Menu button on the Monitor.
9. Press the Menu button on the Remote.

10. Press and hold the Volume button on the remote for 5 seconds and then release the
Menu button on the Monitor. After this step the date will appear on the left side of the
screen within 10 seconds.

Installation of the upgade kit is fairly simple. Just watch the pins which connect to the boards when plugging and unplugging. Sears offers the kits at 178.00. or they did. I'll attach upgrade instructions with the kit number.

Black screen

Had the same problem. Purchased Haier 42" model 42EP24S from Sears and it broke in 1 1/2 years. Couldn't find anyone to fix it so I ordered part Service Kit: TV-3940-01 from the cost was $150.00. If your warranty is up and you're okay with doing your own work. :-)

Replaced 3 boards (instruction included) and my tv is back in action.

Haier 42ep24s 42 in

You need the upgrade kit - make Sears come out and order it for you - they know all about it, claim that the monitor should have been recalled. Mine was out of warranty, however I convinced them to fix the TV.
