Exact same problem with mine mate, and it died very soon after. It refused to come on and would just 'click' away. TV is 24months old. Luckily I took out the extended warranty and Currys have it just now trying to fix it. Will let you know what they come back with!

SOURCE: I have a Samsung LN46C630 that got fried through

I would replace the power supply as they are not too expensive.
New M/board, should be OK. Have you checked the RAM for errors and installed the latest BIOS firmware?

If you have changed these boards you need to first check your Va and Vs voltages, you should see a white paper listing the proper voltages, if you have a way of checking there are TP where you should put meter and get the proper voltage and also pots that you turn to change voltage. Make sure these are there first before continuing Bill.

hello jsinghjassi,
That panel problem. Because short in panel line. If you see in to right side of panel, you can see spark or fire from inside panel.
You must replace panel. It's expensive. My suggestion better you buy new one.

NO HDMI INPUTS ARE WORKING


Hello... If you have satellite and have had a storm, and then you moved the HDMI cable to other inputs to try to get it to work, your satellite has taken out the inputs. You will need the Main board on the TV replaced and your satellite box replaced. In some cases the IC for the HDMI inputs can go bad and cause all HDMI inputs to not work, in which case you will need a new Main board. In rare cases, if your TV is a Samsung, a service center might be able to rewrite the EDID and get them working. I hope this helps...

What board controls the input, my input comes up HDMi and the screen stays black as the HDMI disappears.

How can I repair the back light on a Samsung UN46EH5300F TV? The only circuit boards in the unit appear to be a power-supply board, a main board (the TV tuner plus the HDMI inputs), and T-con board.


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electro-medical.blogspot.com/
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....

My Sharp Aquos Lc32d62u 32-inch HDMI Inputs are not working


T-CON has absolutely nothing to do with HDMI inputs.

it's like changing the front wind shield of a car because it doesn't turn on.

You have a particular IC failed on the main board of your Aquos - maybe more than one - likely due to a power surge through the signal cable.

A replacement of the main should fix that, if not component level repair, but considering this is 32'' unless you have someone really handy around you to help I'd say you'll be better off replacing the whole main board.
