Question about Projection Televisions

1 Answer

My daughter has a sony 50 inch tv .The model # is KDFE50A10. It is 2 or less years old. About a month ago you could turn the tv on and it would cut off and on again by itself and it got quicker and quicker to cut off. Finally it would not turn on at all.When you cut it on the green light would blink a little while and then you can here a switch cut off somewhere where the electric cord comes in the tv and then the red light starts blinking.I tried another bulb,the same kind from our tv and put it in hers and it did not fix the problem. Can someone please help me with a solution? Thanks Jeff

    I went to the web site and put in the model # KDFE50A10 and serial # 8176084 and it said I do not need the software update.I unpluged the tv and pluged it back in and it still did not work.

    Thanks

    I have not cleaned the air filter,but I will try to get to it and clean it as soon as I can. If it is the ballast or thermal fuse ,do you know the price of each and where the best place to get them?

    Thanks

    I have not tried to get any parts for this tv at this time.I took the back cover off of it and checked a fuse and it was good. I plugged it back in and it stayed on for about 3 minutes and then cut off and the green light blinked around 48 times and then it came on again by itself. Can someone tell me if I need to take it somewhere to get it worked on or what the 48 blinks mean and I can fix it myself?

    Thanks again!

    Its possible that the ballast could be faulty or the thermal fuse may be faulty preventing the lamp from lighting. have you tried cleaning the air filter which is located on the side of the set?

    I would go to sonysupport.com and search for an authorized service center in your area. That will probably be your best bet, As sony has had alot of issues with that model and alot of the boards have already been discontinued

I have a sony 50 in rear projection. 9 years old


Sounds like the CRT tubes are going out which is fairly common on Sony. Inside the back of the TV there are 6 knobs - 2 for each color...one is for focus - dont touch - the other for brightness...turn down the brightness just a hair untill the lines go away.

Sony KDS-50A2000 screen is in green tint


My Sony KDS 50 A2000 is 17 months old. Its the 50 Inch SXRD projection model. About two weeks ago the screen developed a green tint with cannot be tuned out, then a few days later the message began to appear on the screen that the bulb was nearing the end of its life and must be replaced.
Fortunately I have the Circuit City extended warranty.
I called and within just a few days a serviceman came out and replaced the projection bulb.
The Result: No change in the picture, the green tint remains on all channels, so I'm awating the next service call. Under the service warranty they have the option to repair or replace this set. If indeed this is the light engine (optical block) which I suspect and its going to cost $1,000 or more I may be looking at a new set.
When it works this is a great TV, but I have had three Sonys now including two other standard CRT models and now this one joins them in the junk heap, the other two also bit the dust after just about two years. Is it time to give up on Sony?
I know they have a class action suit on a similar model for this same problem. Caveat emptor

36" Sony Trinitron blinking red 4 times-PLEASE HELP QUICK!


Sounds like a typical high-voltage failure. Could easily cost another $300 to have it fixed. If it is less than about 6 years old I'd say it was worth fixing. If you want to DIY, then pull all the electronics out (label all the connections) and send it all to either Module Exchange at 972-298-1212 or PTS Electronics 800-844-7871
