Just bought an Alba LCD32880HDF and it keeps switching off and going on standby after 5 mins. I have switched off all timers and sleep settings. Nothing in the product manual to help here :(

SOUNDS LIKE YOU HAVE A BAD LCD PANEL. THE LAMP DETECTION CIRCUIT IS SEEING A BAD LAMP OR DRIVE TRANSFORMER AND IS SENDING A SIGNAL TO SHUT THE PANEL OFF. NOT WORTH MESSING WITH PANEL WOULD HAVE TO BE REPLACED

Ive got a albe Lcd32880HDF And the picture goes off 14 months old sound only?
SOURCE: 32" ALBA 15 MONTHS OLD.
I am afraid it sounds as though either your backlight or power inverter has gone faulty, may be worth contacting alba to see if they will honour the warrenty (unlikely but worth a go) otherwise maybe try your home insurance to see if its covered, failing either of these options, if you feel confident doing so, disassemble the tv and look for any signs of visible damage (capacitors leaking or any components looking burned or scorche, and replace. Try looking for any panel markings which will allow you to search for a price to replace the whole unit.
Unfortunately I cant give you and hard and fast cure, and it is very difficult to tell whether it is the inverter or the backlight has gone (having said that, if you are getting picture at the very beginning, it may suggest that the inverter is getting the power to the backlight ok, which may suggest its the backlight at fault.)
Hope this helps.

This is a common fault as the set on ageing deteriorates in the connections. There is a high possibility that the components over a period of heating and cooling, tend to bring on a problem of dry soldering. So my advice is to check the set for some loose joints that have played on to give you these erratic shut downs or poor performance. The best way to check for loose connections is to tap lightly when the set is powered on , If there is change while tapping then it seems that there are DRY solder joints. Remove main plug, the covers - with caution of high voltage, check for dry joints, use a good soldering iron to solder all suspected points. Sometimes the fault occurs when the set warms up, if so you can simulate the heat using a hair dryer on the suspected areas, try with the power supply, distribution, Processor controller, driver controllers on the A/V related sections. Also the use a FREEZE-IT spray can simulate the components to cool and show up the fault. Based on the above method you must be able to locate the area of fault and solder the sections. Sometimes large IC's- ones with more pins- tend to have drying in some pins and so cause faults related to the IC's protocol. Have a rough idea of looking into the areas to reduce the time of probing. Check for tips to look into the SMPS unit: http://www.fixya.com/support/r5826301-working_switch_mode_power_supplies
