IGO tv connected with dish sound come from tv but pictur not show only blue color show


Component RCA Connectors are RED, BLUE, GREEN for picture. Sound is RED and WHITE. The red and white for sound work the same with the YELLOW that does picture. If the RED, BLUE, GREEN are in the wrong order you will get a blue or green picture. For the sound, try the other red and white connectors nearby. Make shore the right red connectors are connected correctly for sound or picture. Otherwise there could be a cable fault or a TV fault. If you get the picture right but not the sound, connect the sound into a stereo.

No picture comes up but tv powers up and the stand-by light blinks for about 3 to5 seconds, i also hear sound when i turn it on and change channels


If in shutdown the power light should continue to blink a specific number of blinks which is a error code.

This set is prone to bad picture tubes (has 3) so depending on code may be a fatal issue----sets will before flash bright red, green, or blue when this happens and shut off.

Samsung model hlt4675sx\xaa projection tv wont work. the stand by/temp light flashes red and the lamp light flashes green? it makes the sound that it makes when it turns on but no picture. we looked at the...


It could be the temp sensor going bad. This sensor sits on top of the metal housing which the bulb assembly slides into. The bulb assembly will have a hole on top and this is where the sensor is above. There is a small blue and white wire that plugs into it. If you pull the wire out and put a paper clip or wire in the coupling you will basically bypass the sensor connecting the blue and white wire. If your tv turns on then that is your problem. Its cheap too. Here were my symptoms..1] Turn tv on 2] Bulb would light up..(which eliminates the ballast) regular picture would show up (which eliminates the bulb and color wheel) 3] 30 seconds later tv would shut down with 3 flashing lights. After bypass the tv turned on as always and hasnt shut down yet. Always un plug tv first. Get the replacement part to avoid overheating and possible fire

Picture is fine, but the sound won't work


Are the yellow, red & white cables RCA phono plugs?

Yellow = Video
Red = Right Audio
White = Left Audio (mono)

The red, blue & green cables are for picture only and don't include sound. Have you tried using the red, blue & green for the picture and using the other cable, red & white for just the sound? Don't use the yellow.

Good luck!

Sanyo ds31590 picture's very dark and red


sounds to me that your picture tube needs rejuvenated.
You will need to get it done by a tech.
mechanical doesn't mean a thing when it comes to electronics.
Mechanics when working on electronics, end up costing more damage when you end up taking it to a tech.
