Hitachi 32HXC01U LED

[viduka]

Hi
Can anyone other any advise. Got a Hitachi 32HXC01U B
The TV powers on stays on for a second then powers off and comes back on. It does this continually.
Replaced the Power board but still same issue. Any ideas ?

this sounds like the one i repaired recently turned out to be a bad mainboard.

Basically they are very poor boards - but I am sure you must know that already.
Is the board shown the "new" one and how was it described when you bought it
- any guarantee?. Was it your set - have you ever seen it on.

The Board shown is the original board. The replacement came with warranty ect from EMOS in the UK. Used them several times with no issues. All boards are fully tested.

Too many issues with EMOS myself to recommend them, plus they are pricey!
12V, 24V, 5V from PSU steady?

I have no idea where to check the voltages on this board. I know how to check but don't see anything on the board that tells me what the Voltage on the connector should be. Any pointers would be great.

Nothing on the back of either board - I cant really see on your picture if on the front
Well on the black connector to the main board just put your black probe on a nearby ground screw and with the red probe start at one end and test each pin.
Meter on vDC200 The other connector which I guess is for the leds with the black and red wires may be a higher voltage but is on the "Cold "side so not too high.

this was my thread

on the main board under the white oblong sticker is the main board part number can you peel it off and see what it is and selldoor there are no markings on the psu or main to tell any voltages but tom came to the conclusion its a mainboard issue i purchashed a new one works fine ever sine a hd ready led set with freeview etc.
what colour is the standby led flashing just red or red and blue?

@ Vince - thanks- another thing if you can recall? the connector main to power does it just have one row of pins? as on your pic on the main it looks to have 2.

two and very hard to test hence checked the regulators for voltages
