deejah Posted August 5, 2012 Share Posted August 5, 2012 tv screen will flash weird colors then go black for a second or two then be ok for a couple or a few minutes can hear the sound fine even when picture is black or flashing i tried changing out with another of the same TV from a diff apt unit but then the other TV started to do the same thing i also tried different combinations of plugs and connectors but right now i am stumped i thought it might be the DVD player, the AC plug, or the TV cable but tests pretty much ruled all of these out it seems that there is something interfereing with the proper operation of the sets in my unit after years of no problems like this before can anyone help please? thanks Link to comment Share on other sites More sharing options...

endure Posted August 5, 2012 Share Posted August 5, 2012 He's already tried a different TV and the fault remains. How will buying a new TV fix it? Link to comment Share on other sites More sharing options...
keeniau96 Posted August 6, 2012 Share Posted August 6, 2012 Sounds like electromagnetic interference, some motor or circuit. Could be in your place or outside eg. aircon unit, even traffic light. Link to comment Share on other sites More sharing options...

sysardman Posted August 6, 2012 Share Posted August 6, 2012 (edited) Sounds like electromagnetic interference, some motor or circuit. Could be in your place or outside eg. aircon unit, even traffic light. It wasn't totally clear if this was a problem just watching normal TV or does it do it when watching a DVD?. If it's just normal pictures then it sounds to me as though the distribution amplifier is on the blink. If it's just your apartment affected then it may be that one output, if so ask your landlord to swap you to another output from the amp if there's one free. The norm for these apartment blocks is a large aerial connected to a multi point distribution amp that in turn feeds all the apartments. Another possibility is rain seeping into the cable feeding your room but then you would need a TV engineer to replace the cable - you could try using a coat hanger as an aerial just to see if you get a steady picture with that.

timber Posted August 6, 2012 Share Posted August 6, 2012 We had some unusual problems with our Samsung. Lines problems with picture then it quit. We called in Samsung. They cleaned it and everything was ok. Cost a 1000 baht. Link to comment Share on other sites More sharing options...

sotsira Posted August 6, 2012 Share Posted August 6, 2012 Do both TV's work ok in another room? As i had a similar problem with an old Samsung tv 4yrs old and it was a faulty voltage regulator inside the unit. Samsung couldn't repair it due to unavailable replacement part. They also told me that this was a common problem with their old tube style tv's. Link to comment Share on other sites More sharing options...
bangkok101 Posted August 6, 2012 Share Posted August 6, 2012 i am certain that there are cockroaches in the crank shaft, and/or fleas in the flumigator. Ok, its obvious the TV unit is not faulty but there is an environmental impact from something in the location. What happens if you relocate the set, same problems, or normal operation? Work backwards and identify any changes to the environment where the set is located and try to eliminate each change, one at a time until you identify whatever is interfering with normal operation of the TV. Have fun. Link to comment Share on other sites More sharing options...

Have fun. Sounds like a plan!! I was basing my ideas on it being unlikely that 2 TV's would have the same problem but if I'm to believe other posters then it sounds like those Samsung TVs are rubbish. Unusual 'cos Samsung stuff is normally pretty reliable. Link to comment Share on other sites More sharing options...
deejah Posted August 15, 2012 Author Share Posted August 15, 2012 (edited) get this: when i open my old laptop the tv acts up close the laptop and all is fine so there is something going on tv verses computer or tv verses wireless i also now suspect computer users in other units in my building may also have an effect on my tv screen but the flashing is more muted thanks for the intelligent responses Edited August 15, 2012 by deejah Link to comment Share on other sites More sharing options...

If you are using wifi then there is a problem because wifi frequency is way above TV frequencies so should never interfere with each other.

Jdietz Posted August 15, 2012 Share Posted August 15, 2012 So the problem is most likely a faulty power brick on your laptop, causing EMI. Link to comment Share on other sites More sharing options...
