Techwood LCD TV - picture fault

Hi

I have a Techwood 32722HD LCD TV, 32". Three months outside its twelve month warranty.

A few weeks ago the picture went odd. It is watchable but far from right. The only way I can describe it is like green 'interference' where the picture has darker colours. Only way I describe it is that the image looks pixalated in places. I have re-tuned the tv and cable box, no different. I have played with the cables to see if what interference, but no difference. Tried it in a the bedroom with different cable box and scarts etc, no difference.

The sound is fine.

Any advice greatly appreciated.

Cheers

Gordon

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary. ..

Push your red component cable firmly in the tv and the cablebox and you will be good to go.

SOURCE: No sound on my 32'' Insignia LCD HDTV

I have a question? Do you move your Television frequently, OR do you unplug it frequently when it's not in use? I have found that doing either or both of those things can bring on problems, especially audio problems.

I've had the disappearing sound problem twice with my Element FLX-2610. This latest time I was stumped because the full scan didn't resolve the problem. And of course, the sparse manual that comes with the TV contains no troubleshooting advice at all.

But I did find a suggestion on another sveral other sites: Reset the TV. You might have a small reset button (like you would find on a DSL modem) somewhere on your TV but there is a manual way to do it two. Whichever way you do, MAKE SURE to disconnect every single device (yep, it's a pain) and UNPLUG the TV before doing this.

To reset with a reset button, disconnect devices and unplug the TV. Depress the reset button for 5 seconds. Reconnect devices, then plug in the TV.

Manual Procedure:
Disconnect all devices
Unplug the Television
Using the on/off button on the Television (NOT on the remote), depress and hold the button for 5 seconds.
Reconnect the devices, then plug in the TV.

Unless something has shorted out or burned up inside, this resetting, as a last resort, should fix the audio problem. Worked like a charm for me!

Good Luck!

SOURCE: technika tv lcd 19-907 tuning in to sky in bedroom.

Hi i had the same problem but i have sorted mine now. What i was doing wrong was i wasnt tuning in the analoge channels only the freeview digital ones. To do this you need to first turn your tv on. Then press the "source" button, this will bring up a little menu at the top left hand side. When this menu comes up press the "Programme +" button (the one that you use for changing channels near the volume button) press this until you get up to "TV", when T.V is highlighted just wait 3 secs and it will switch over. You will probably get a blue screen with a no signal message (you are now on analogue) when you get this blue screen press the "tune" button. It will automatically start tuning in all of your channels, at first they will be fuzzy but as it works they will become clearer. Your sky channel will also be tuned in. When mine tuned in it didnt tune them in on the right numbers though, bbc2 was on number 1 etc. If you ever need to use a playstation or something it goes into the scart connection at the side of the t.v and you need to press "source" and go up to "scart". To get back onto the digital channels just press "dtv/dvd".
hope i helped!

SOURCE: Fuzzy pic on Dynex 32 LCD TV

I am sumising that you have checked the menu controls on your tv and are recieving your signal from the cable box , so therefore if it is not comong from the Aerial and direct from the cable company then the picture should be clear .. However sometimes people dont check to see if the signal is RGB or composite from the box RGB is usually best if you have a scart socket connection or SVHS if your set has that capability .. sometimes people have an old VHs recorder and the sinal is coming from that to the set through the Aerail fly lead if it is you will probably find they are conflicting giving you a poor picture retune your Video to another channel instructions should be in its manuel if not come back to me ... reagrds Vortash

Tv is on with no picture or sound, only 4 months old!!


Hello
The power supply regulator board to your set has the fault. If you try to open the set, or try to repair it by yourself, the warranty will void. The set must have warranty as it is new. Why do you spend for it? Just contact the nearest authorised service center for Sceptre. the components in this set will be very hard to get from open electronic spare part market, and will costly too.

If the signal has not changed, then the problem is internal to the set. Given that this unit is only a few months old, it is still under warranty. Request a warranty repair. This should be repaired or exhanged at no cost to you. It sounds like the digital processing section is defective.

Buzzing


Mine has the buzzing. I even created this current one out of 2 damaged ones, the original internals did it as do the internals I took out the "new" one I got (it had a smashed screen). I noticed it stops completely when muted, but not when the volume is on 0. It also gets louder when the contrast is higher (just flick between the preset PICTURE MODE's). I think it's something to do with the internal speaker cables perhaps running too close to the display circuit or whatever (Im not sure what causes it, its normally electrical interferance being picked up by an unshielded cable). I'll no doubt get hacked off and reopen it soon to look about. I'll post back when I do, may be a few months though!

Samsung lcd sound no picture


I don't know when you posted this question and I can tell you that I am quite furious with Samsung. My TV 52 inch, started to turn itself on and off on and off every 8 seconds. I did get in touch with the Samsung people and they told me that I could download firm ware that would fix it, but because the tv wouldn't stay on long enough for the menu to come up we couldn't do it. My TV has been out being fixed? in my town for 7 weeks. I just got a call and it is on the way. He told me it was the t-com board and I asked him if the part was new, and he said yes. It better be after all of this time. I did see that you can buy a t-com board on e-bay just a few minutes ago. If you can get your TV to the menu go to Samsung's site and look for a firm ware upgrade. They knew this was going to be a problem and they should have been recalled.

Tv is unresponsive


Does your set have a reset button on it? It sounds like we had the same problem from the beginning. In fact, we have bought and exchanged the tv 3 times because we thought maybe we just had a lemon. The picture would freeze and no buttons would fix it. We read in the owners manual about the reset button -- a tiny hole in the top of the power button on the right side of the tv. You can use the end of a paper clip and stick it in the hole to reset the tv. The tv powered off and then the remote and all the other buttons worked. Ours is still in the warranty but for the first month, it seemed like this happened at least 5 or 6 times. Haven't decided if we want to try to exchange it again or just live with it. Other than this, we love it!
