LG228WA - 2 years old, Pink Screen

LG228WA, owned for a little over 2 years now, all of a sudden when powered up returns a bright pink accompanied by a green streak vertically placed down the left side of my screen whenever a source (RGB/DVI/AV/RF) is detected. How can i fix this and what is its cause?

    Thanks for the prompt reply louie12fix, the problem started yesterday after switching channel from AV2 to RGB (PC Input). The unit was bought brand new from PC World, i'll have to check to see if i still have the reciept in the box.

    The unit itself is pretty much in operation every day for around 3-12 hours, it sits alongside a Samsung CRT which has been around a loong time.
    The connections i generally use on the LG were the VGA/DVI/AV1/AV2 and the jacks IN/OUT (to external speakers), i literally never really used the 3w speakers built in.

    Regarding your suggestion about refurbishing with new parts, roughly how much would i be looking to pay to repair the unit if what you say may be the cause ?

Assassin_noi, Very good description of WHAT you SEE. Did you buy unit 'new' ? How many "ON" hours does unit have? To fix this you should first check with Lucky Goldstar LGI and see if they have a prorated exchange program for PREMATURE monitor failures. It should at least worked 3-4yrs. Well your symptom could mean almost anything, but i suspect that it will end up being a internal switch-mode-power-supply failure and/or INVERTER supply failure. A trained Technician will need to evaluate your unit and determine if it is viable for REFURBISHING the unit with new CCFT lamps and /or rebuilt SMPS/Inverter supply. Get back to me if this info not enough. Im louie12fix on fixya or lmistyrel Bye for now.

    assassin_noi, Don't know if I can be of much help to give you a estimate of $ required to restore your unit to like new condition. I come from the "industrial electronics" side of the electronic world in which we live. Parts and labor and test equiptment use are free of charge given the right circumstances. So here goes it at a "best guess LOW SIDE cost estimate" in u.s.$ $10. for Tear down. $15 for .5hr of troubleshooting $10. for new capacitors for SMPS repair. $10. install new capacitors and test and burn-in unit for 2 hrs. Yeah, let's add $5. to screw it all back together. $50.00 is what would seem about right to me. But that's me, coming from PLANET FREEBIE!!!! But before you do anything else, find out if GOLDSTAR will help you out first. I really think that the "life-expectancy" of a device should be a little longer than 24 months!!!!! I mean, hell! this gateway LCD I'm using is more than 60 months old and used abt 5hr/day. Hope this helps you? louie12fix on fixya or lmistyrel @aim.
