Question about Sharp LC-37D4U 37 in. LCD Television

1 Answer

Set up only visible for 2 seconds, then black - Aquous lc-37d43u

Screen set up comes on briefly then goes black.

Same thing happens each time we power on. I turn on the power, picture and sound will last for 2-3 minutes and then turn off. The power light will flash twice as well as the OCP light, then the OCP light flashes 5 times and then returns to the power light flashing. Can I repair this.

Unfortunately I can promise you that you CANNOT repair this. Your power and opc lights coming on, but the tv is not coming on. That is a issue within the tv. Give sharp a call and they will have somebody come fix your tv free of charge, if they cant fix it, they will replace it for free. That is the only thing you can do. Sorry bro

I have a sharp aquos tv model lc-32m400x. When i turn the power on via button at the back the green light comes on for about 10secs then turns to red and flashes about every 11/2 - 2secs. Any ideas.


Those 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.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.....

If the converter goes out does the tv not do anything no screen light uponly red standby light?


if your question is that if cable or sat converter goes off for any reason , will your tv display a black screen , then the answer is yes , without an input most all tv sets will display the opposite of full white , this being full black , also any on screen displays might not work as well (no video to sync too)
