SOURCE: Can't turn on from Stanby mode

I would assume the power board has a problem. A tech could possibly repair it without replacing the whole board.

SOURCE: tv wont turn on

Hello Charliebigwh, hi technically your monitor's power supply has a problem, this is either your switching regulator does not work or there is a short in that section, If you want to do it your self, need to replace all large value, and or high voltage capacitors(especially the capacitors with its top is bubbly), need also to replace the switching IC, and power transistor.

Have it checked by a technician if you cannot do the work.

Firstly, try changing the batteries. If you've already changed then the remote has probably lost the TV code.

If you can post your exact Alba Model number, I will post the correct code and programming instructions for you.

It would also be useful if you can post you Sky remote version number - it's on a sticker in the battery compartment. I need to know if it's Rev 8, Rev 6, Rev 4 or just RC1600/00.

Hi,

the issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge........

The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board. You might be lucky it's just a blow fuse. Also a defective transformer can cause your TV not to power on.

All these can be checked on the power supply board.

But more often bad capacitors causes problem on the power supply board. I do not think the power board needs replacement, rather those defective capacitors is causing this issue. Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.

The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes).

You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.

What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).

You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors). After replacing these capacitor(capacitors) most likely the normal operation will be restored. Or you can by a refurbished complete power board to save you some stress.......

Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.
If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.

Yours sincerely.

Elect_Comp.

I have just purchased an LG32lcd 450 tv, I cannot get the handset on Sky to work as they do not have a code to do this as the tv is new to the market, can you please help with this


Hi,

OK, as you already discovered there is no specific code for your remote. You can try the generic codes for LG which I've listed below. Your TV may use the same flash patterns as some other older LG TVs so these codes might work.

Rev 8 remote: 1293, 1206, 0206, 0065, 0904
Rev 6 remote: 0065, 0742, 0502, 0672, 0634, 0136,
Rev 4 remote: Same as Rev 6
RC1600/00 remote: codes not available and unlikely to work with your TV

** Your Sky remote version can be found on a sticker inside the battery compartment. **

Try these codes but if they don't work it's unlikely your remote will work with your TV - you will need to use the remote supplied with your TV to control volume and power functions. Unfortunately, when a TV is newer than the remote and uses a new flash pattern not programmed into that remote, the remote wont work. However manufacturers often keep the same flash patterns for common functions, so the generic codes might work for you.

I'm informed that a new Sky remote version is due - which will hopefully contain a specific code/flash pattern for your TV - but I've not been able to confirm this yet.

Hope this helps - please post back if you need further assistance.

TV is in stanby/timer?


There are any number of things could be wrong here. If you have an ever so slight chirping sound coming from inside the unit when you press power could be defective crt driver Ic702 which is a Tda6108 and a common problem for these sets. Could be regulator or flyback and could even be vertical Ic which is a Tda8172 and just the way that circuit is designed, without full deflection from a failed Ic, the shutdown would keep the power off...
Best advice here is take it in to a qualified shop and have them estimate it, you'll be money and headaches ahead..
