Red light but no power - alba tv please help

[SmartestSmarty]

Dear all,

I have an alba tv, and it will not turn on.

The red standby light is solid, but when I click the power button on the remote or the set; It will not do anything at all.

I have opened it up and can see two capacitors have a reddish dust on them. Do these need changing?

Model #? Pictures of the boards and of the suspect capacitors?

Hello I am not with the TV right now, but I will definitely update this thread with the model number as soon as I can.

I have attached an image so you can see the suspect cap.

Just looks like factory markings, nothing wrong with that - also looks like that power board outputs one voltage only which is always available so you can check to see if that is testing OK.

Hi thanks for your reply.

How would I test it.

I literally can't see what else could be wrong with it.
Any suggestions what could be the problem and the solution?

You would need a digital multimeter, do you have one or could you borrow one? A relatively inexpensive bit of kit; Maplin sell them for under £10 each.

I have one.

But never used it to test a board.

Any advice?

Perhaps update your profile with country and voltage so we know what voltages we are dealing with.

I'm not sure what the line voltage would be for United Kingdom?

Prolly find its the mainboard thats at fault. Confirm there's 12v coming from that PSU first...

The pins on the PSU are marked what they are...

Plug Black lead in COM,Red lead in VmA above it, Set meter to V-20 to the left of off,Black probe to any fixing screw on power board, Red probe on wire connector next to caps start with top red wire and work down, and let us know what the meter reads Flocko

Hi thanks for your reply.

All except the last two read between 0.01-0.02 for about a second and then went to 0.00.

The last two read 0.00.

The red power light is lit, I don't know if that helps?

Any suggestions whats wrong, or what to do next?

You can't be testing it correct then, if you get 0V there the power light would not work. Show us what your meter is set to please.
