Question about Goodmans W280NS Television

1 Answer

Distorted picture I have another brand which is the Techwood 37722 and it uses the same Vestel main board17MB15E-7 as the Goodmans LD3755HD, Hitachi 37LD8700UH and Toshiba WLT68. The fault is similar after 10 or 15 minutes the picture becomes two distorted images and sometimes four with coloured bars. Initially some weeks ago there were faint diagonal green lines but I changed the PSU and they disappeared. The duration which a normal picture appears seems to be getting shorter.

How to rechannel techwood tv wtp4210 from uk to phillipines pls, help


Techwood, is made by vestel Technologies for AO
TV How To Guides

unsure if you are trying for basic terrestrial transmissions (plugged into on-board Tuner) if so follow the guide above.

if you are trying to attach a digital tuner, that should just plug into the HDMI port and should work straight away.

if you are trying something else, or the above is not working please let us know, and I will try to resolve.

Goodmans LD3755HD Picture Problems


Hi,

Pls try using the TV with pure video signal only such as a DVD or even an old VCR. If the problem persist with the DVD, then yes it could be the video processor, if not than chances are it is the built-in tuner of the TV (most likely). Since the tuner block is a single assy, then it would be relatively easy to identify and replace. Often, it would look something like below.

If on the other hand, it is the video processor, then your best would be to get hold of a service manual or at the very least a schematic diagram with voltage readings if you are considering a do-it-yourself repair.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Techwood flat tv wont turn on for 3 days


Fault to the main power supply regulator section. Either it will be on a separate board, or on the part of its main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
http://electronicshelponline.blogspot.com/
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

The problem you have described occurs due to a faulty LCD controller(T-CON) board. The board is inexpensive(costs around 40$) is easy to replace. Let me know if you wish to do it yourself so that I can help you find a replacement part and fix it.

You can get the USER's manual from;
http://safemanuals.com/314159.php?k=8391d3906c77608652c0aeebfd8fdc85&ID=567120&q=GOODMANS GHD8015F2

after entering a security code to proof you are not an automated software bot.

Here is some information I got from a forum you might find useful. If you can find a service manual for the same model under a different name, it should work.
--------------- ------------------ ------------ ------------------
I had a few recording on the Freeview box I wanted to keep so decided to extract them from the Harddrive and archive them on my Vista Premium PC.
Here are a list of the re-branded machines made by vestel obtained from http://www.futaura.co.uk/vestel.html

Digihome PVR80 and PVR160 (Argos)
Dual DPVR80 and DPVR160 (Asda)
Evesham PVR160
GOODMANS GHD8015F2
Grundig GUSTB80IV and GUSTB160IV
Hitachi HDR080 and HDR160 (Argos)
Maplin PVR80
Sharp TU-160H
Techwood PVR80 and PVR160 (Tesco)
Here goes with what you need to do, hopefully preventing other people going down some blind alleys as I did. You'll need a basic knowledge of PC DIY, but nothing too advanced.

Obviously taking your PVR to bits will invalidate the warranty, and there's a risk you'll damage it if you're worried about this don't do it!

Here goes....

1. Power the box down and disconnect from the mains.

2. Take the lid off, about 8 screws, four on the back and four on the sides.

3. You can now disconnect the IDE cable and power connector from the Harddrive. The easiest way to connect the drive to the PC is by use of an IDE USB Harddrive Caddy, that's what I did. Otherwise you're into opening up you PC and connecting it is as a secondary disk.

4. The disk has a Linux file system on it so Windows Vista will not recognize the disk, so you need to get a windows EXT2 file system driver.

5. I downloaded and used Ext2Fsd-0.46a.exe from here http://e2fsprogs.sourceforge.net/ext2.html

6. Run this and you'll see the disk. Mine had two partitions, you'll probably have to assign drive letters using the ext2fsd utility. I set mine to K: and L:, I connected in read only mode to ensure I didn't corrupt the disk.

7. You should now be able to see folders and files on the drives. One of my disk partitions was 75gb the other was 5gb. The recordings were stored in folders on the large partition. (I'm guessing the small disk is used for Pausing live TV)

8. It appears there is one folder per recording with a name showing the date and time the program was recorded. Something like this:

~dvr20090000191304000501.rec

9. The recordings are numerically split into individual files of about 190mb each (00,01,02 etc). Something like this:

dvr20090000191304000501.rec00.trp
dvr20090000191304000501.rec01.trp
dvr20090000191304000501.rec02.trp

10. I copied all of the folders and files to my PCs Harddrive, just in case something went wrong, I didn't want to damage the PVR disk contents.


11. Now you need to do a conversion to allow the files to be viewed by a suitable player, again pretty easy and here is it what you need to do.

12. You need to get a program called ProjectX. I got it from here:

http://download2.videohelp.com/downl...X_090.4.00.zip


13. Extract and install this program, it'll also install a Java compiler.

14. This program will convert the multiple ".trp" files to ".ts" mpeg transport stream files which can then be opened using the videolan media player.

15. When you run ProjectX you'll need to add the sequence of ".trp" files to the bottom pane of the main window. Make sure you have the lowest sequence file number at the top of the list i.e. 00 and all the other files are in the correct order, you do this by selecting the up or down arrow to the left of the pane.

16. I found you can drag and drop the whole sequence of files from windows explorer to the pane (just check the sequence order is correct order after the drop as per step 15 above)

17. For the first time only you need to click the prepare>> button on the left of the preview screen. All I did was select the radio button to the left of the "to TS" selection.

18. When this has been done just click the go button (Green arrow) and it'll process each file and stitch them all together to produce a ".ts" file in the folder where the ".trp" files are stored. This ".ts" file can be played by videolan. This process is quite quick as it isn't re-encoding the file format.

19. When you process the next recording you can skip the prepare>> steps (17 and 18) and just click Quickstart. I got problems when I tried to process the next recording so just closed ProjectX and started it again after each recording. I'm sure there's a better ways but it worked for me.

20. I believe you can use ProjectX to convert to formats for archiving to DVD, but I wasn't interested in that so didn't go any further.

21. I wanted to view directly from my PC so I used videolan mediaplay which can be obtained from here.

http://www.videolan.org/mirror-geo.p...9.8a-win32.exe

22. Installation of this is pretty straight forward and once you've installed it, all you have to do is double click on the ".ts" file create in step 18 and you can watch the files on the PC.

Thanks to all those who provided the pieces of information that allowed me to produce this single guide. I hope it helps others. Please correct/enhance as you feel necessary
