Alba LCD1988OH DF Stuck In standby

[anotherdude]

Standby light on the front appears but no response from the TV when trying to turn on.

Have changed C807 but still the same. Can't find any schematic for this power board, 17IPS16-3 V2.

Took readings from the pins leading to the mainboard.

Not labelled so from left to right (using the pictures orientation)

PIN1: 0.00
PIN2: 0.01
PIN3: 0.65
PIN4: 2.21
PIN5: STARTS AT 1.70 DROPS TO 0.90
PIN6: 5.29
PIN7: 0.60
PIN8: 0.01
PIN9: 1.51
PIN10: 0.00

Do a 'self test' on Power Board. I think though your problem is Main Board.

ok, got a little further, have no remote for this set so tried using a universal remote but the codes don't work so put it into search mode and heated up the p[ower supply near the caps.

After a few minutes of heating then getting the remote to search I can now power on the tv with the remote but the buttons on the side still can't power on the TV, but can power it off.

Leaning towards bad caps?

Got to try the buttons again and tried changing channels, got a child lock message on screen, have disabled it in the menu and the power button now turns the tv on

Went into the service menu to see if there was anything obvious and to do a self check.

The hotel mode has a YES next to it but I can't seem to get this remote to turn it off.

I can't get the source button on the side of the TV to work, if i continuily press it it will eventually show the source list, would this be part of hotel mode?

Not sure if this main board is even correct for this TV, in the source list I can see YPBPR, yet the board doesn't have this connectivity.

If I choose FAV from the list I can get COMPOSITE to display, all other inputs works fine too.

I've seen a Youtube video showing that Hotel mode can be used to inhibit a number of functions and may well be set to inhibit the use of the side buttons so as not to have access to change channel, or volume etc.

Ye i was thinking that but why would it work after "x" tries, unsure why YPBPR is listed as a source.
