Question about Toshiba 27D46 27" TV
I got this from someone who told me the picture went out but there is sound. I transported this tv to my house plug it it and it displayed a picture with sound. when i went to replug it , again no picture... please help.
It would seem that there is a loose connection or even perhaps a cold solder internally.
What needs to be done is to open the back of the unit start checking the multiple connectors to the PCB. Unfortunately this has to be done with the unit live and with the use of a mirror to be able to determine in which area/section that the picture will be restore. You would need of a bit of insulated rod about 1 to 1 1/2 feet long to move the wires and push a little on the connectors (a broken fiberglass fishing rod would be perfect). Determining which one is pretty straight forward. Correcting is simply inserting the erring connector more firmly to the socket/mate.
Cold Solder is done very much the same way but rather than wires and connectors, you would need to push on the terminals/leads/pins of the components. Alternately, you can turn the PCB board over and with the use of a strong light and a magnifying glass, visually inspect the solder joints. More often cold solder develops on high powered components such as high wattage resistors, diodes, transistors, regulators. Corrective measure would be re-applying heat through a soldering iron.
Both the above requires familiarity with electronic circuits and components, use of a DVM and a soldering iron. If you are comfortable, you may need to seek the services of a qualified professional.
hope this be of help/idea. Pls post back how things turned up or should you need additional information.
good luck and kind regards.
