TV flickers intermitantly

Hey, i bought a tv a few months ago, its a flat screen plasma HD tv.

after a few days of use it started to flicker intermitantly and after a long argue with the people at the shop they said they would send it back to the manufacturor.

severl weeks later it has come back ( after they replaced two components inside it ) and worked fine for a few days however the exact same problem has come back except for the fact i can some times fix it with a sharp smack on the back...

does any 1 have any ideas whats causing this?

The TV flickers off and on causing the screen to go black intermittently when our furnace runs. If we turn the furnace off, the picture straightens up and when we turn the furnace back on, the picture...


The TV could be wired to same breaker on the furnace. Or the cable line maybe cut or rubbing on electric line for furnace which can cause interference. Check each wire make sure there isn't any bare wire showing. good luck

My Panasonic 27" Omnivision TV set (PV_C2542) flickers intermittently until I jiggle the cable conection into a new position. Sometimes the TV image goes off entirely and appears as a blue screen....


your tv set need parts Resoldering.
intermittent color changing is cause by cold solder joints.
have it serviced by a reliable electronic repair center or person.
you should not be charge a lot.

if you wish to fix it yourself,
you need a Soldering Iron (about 60watts) and soldering Lead (60/40).
air blower (for fast Cleaning) or
[1inch paint brush (for cleaning)]
unplug and place your set to your work bench then open the back cover.
(since you say its old, expect lots of dirt/dust inside your set, use the blower for easy cleaning).
if you have completely access of the solder side of the circuit, just resolder the joints. BE CAREFUL... DO NOT CONNECT SEPARATE JOINTS.


if you don't have experience with electronics i advise you have it to a repair person.

hope this helps you!

All TV's in house failing, a few at a time


Hey PNorris,

If multiple electronic devices are failing in your home all at once, I would probably first have to ask if your home recently experienced an electrical storm or major power surge of any kind.

Normally the effects of such large-scale surges are immediately noticeable - TV's and other major electronic devices may fail to turn on, fuses may be blown or circuit breakers tripped, and in some cases electrical wiring may be melted.

If nothing like this has happened recently, low-level power surges may still be a potential cause of this problem. When the motor from any large appliance (such as an air conditioner or refrigerator) turns on or off, it often diverts power to and from other electronic devices using the same circuits. This fluctuation in electrical current may result in low-level power surges to every connected device. While not immediately noticeable, these low-level surges can often cause the eventual failure of (and gradually degrading quality in) many audio/video components.

Typically, the easiest way to avoid situations like this is to make sure that outlets are not overloaded and surge protectors are used with every major electrical device in your home. For older homes however, replacing the house's wiring may be necessary. Homes that were originally built at the turn of the 20th century may not always have wiring capable of supporting the electrical needs of many modern appliances.

Ultimately, this means that in addition to contacting your local TV repair facility, you may want to also speak with an electrician. This is probably the best way to determine whether or not power surges have caused these failures, and may give you a better idea how to proceed.

Hope this helps you out.

Sincerely,
Aaron
Go Ahead. Use Us.

RCA model# D61W136D scenium


Sounds like the high voltage transformer is bad. Best bet is to call a service shop. I wouldn't keep watching the set, as this will just cause more damage.
