Question about Sony KDF-E50A10 50 in. LCD HDTV
Bought this projection tv (netherlands,Europian model) in 2006, in april 2009 it started to get blue blobs on the screen, first small but were growing larger fast. Called the internetshop i bought it from about this but they said i had to pay myself because it was out of warrenty.At first i was thinking it was a lamp problem, so i bought a new one (expensive! ) But that was not the problem. I found a lot about this problem all over the internet with the American model and also the fact Sony even refunded or offered another tv with large discount for some of these models.(also about the lawsuits in America), so i was thinking i had a strong case against them, and got in contact with Sony about it, but all i got from them was that it is a totally different model and has nothing to do with the europian model. I was free to sent them the tv or let one of the sony people get over to check my tv but on my own expense, and it didnt help telling them i payed over 1400 euro in 2006 for it,then a new lamp for almost 200 euro, and problems started after 2,5 years...at this time these sets arent being sold anymore (wonder why!) I got so tired and upset over this bad customerservice, i had the tv removed to the attick,and bought a new one, a 60" LG plasma this time.
Last week my hubbie gave it a try to repair it himself, he's into computers, and one of the companies he's doing repairs for is into home consumer electronics, they helped him with a new blue prism (not sure if it is called this way btw, and after opening the set, cleaning all these dusty parts (found instructions on the internet where and how), and putting the new blue prism into place, the blue blob was close to vanished, only a few specks left here and there. But it all had to be perfect again for my hubbie, so he went on and opened it again, cleaning and cleaning with cotton swabs.
Now after this all he wanted to try to get it even better by changing some settings in the service menu...and this is where it all went totally wrong, after changing some settings and leaving the service menu the screen stayed dark, only sound came back on. He's in a state of throwing this set from the roof by now; but hey, it can't be so there is no way to resolve wrong settings? He also feels guilty doing this, even more after the fact we were not able to find the service manual for this model (kdf-50A11e), we did for the American model (kdf-50A10) but its not the same, at least not with input-commands, because the remotecontrol is so different also.Entering the service menu is different too between these two models, but there must be a 'secret' code to for example reset settings in service menu back to factory/default settings?
Hope someone can help me to get any further with this problem, at least to get the picture back....Darn, sometimes i wish we still had the old fashioned tv's, they lasted at least for over 10 years or more!, LOL
Thanks in advance for help/advice, Yvonne from the Netherlands

A 4 flash issue means either the back light inverter (power supply) has failed or that one of the fluorescent tubes in the panel has failed. The only way to know for sure is to check the fuses that are on the inverter board. If one or more of the fuses are opne, then it is likely the inverter board is bad. If the fuses all check good, then the panel is at fault. If it is the inverter board, it is a part you could replace yourself; the cost of the board is about $70. If it is the panel, you would probably want to consider replacing the TV, as the repair costs would be over $1000

You are going to find it is a LCD panel problem. I am sure that they will take care of you. But also realize that this could have happen to any brand of LCD panel and you will probably not have any other panel issues once it is fixed.
I feel your pain,

This could be caused by dust on the bulb. Dust can cause the unit to over heat and will shutdown for a few seconds to a minute and then come back on when it has cooled down. This time can vary depending on the location of the unit and the temputure in the house. The dust becomes hot and so the Thermal unit shutsdown for a short while and then comes back on.
Clean the bulb by removing the cage and using compressed air and a micro fiber towel and install back intot he unit. Make sure you follow the Sony Maunal. Also make sure not to touch the bulb as the oils from your skin will cause it to burn out quickly.
