Why does the power indicator on my LG 32LD550 Flat Screen TV blinks slowly and I have no picture/sound?


Main system control memory IC fault. Contact any service technician.
These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience.

My picture and keep on breaking up on some channel


If you have a good picture on some channels and the picture breaks up on others , it could be the input signal. What is the source of the input signal; i.e. cable, satellite, antenna???? Do you have a cable box? The problem may be with the box or with the provider's signal.

Picture scrambles and smears out


Sounds like a T'Con fault. If the main processor IC on this board is faulty, it will overheat with time, and the picture will fade out accordingly. If you wish to get some details, check the site linked here. Pull up older posts. Check the site in 'Mosaic' view. It will make search easy. http://electronicshelponline.blogspot.com/

Breaking sound and picture


Hi, Breaking sound and picture is usually a result of a poor signal into your TV, check the aerial cable and connectors for poor connections, perhaps re-do the aerial plug connections if you can, if this doesn't solve the problem then it could be a fault with the actual aerial.

as a second thought you may have an aerial amplifier, if you do make sure it is switched on and check all connections.

Hope this helps.

please let me know how you get on.

Good luck - Midge.

When I turn on my Gundig TV the sound is there, but the picture does not come for about 15 minutes. It starts off blue then slowly changes colour and eventually comes on. The TV is only 16 months old....


Hello
It may be due to the fault of its picutre tube base socket. Some of them may show this type of fault eventhough it is a new one. Picture tube base socket is located at the picture tube bas card itself. It is directly soldered to the base card, throu which the connections are going into the picture tube via its pins. You just open the tv, and pull it out [not make any shakes while pulling it, as that may bed the picture tube pins, or iven break the picture tube neck. Just pull it straight out, and refit it at the same way as you pulled it out, for two or three times. Sometimes this will retify the fault, as this process will remove any loose contact between bascard socket and picture tube pins.
If this doesn't hlep, desolder it out from the picture tube base card, go for a similar type and pin confuguation. Replacing it will solve the problem. As you replacing the base socket, look into the base card for any loose soderings are there too. OK.

No picture


Common faults that give you no picture and sound on Plasma are often related to Sustain board, buffer and cables problem.

In this case the cost will be affordable, ans surely worth.

In the unlikely eventuality that instead you have a faulty plasma screen , or a faulty digital control board (main board), the cost of repair may be high.

The only way to find out is by having the TV inspected by a technician.

The most common fault that gives you no picture and sound on plasma is Sustain board , lower buffer, or connector, that is repairable.
