20 Most Recent Sony KDF-E55A20 55 in. LCD Television - Page 9 Questions & Answers

Hi
I would be very careful about blindly ordering parts. This is where a reputable service person could help you. My first impression is that parts have begun to age in the set thus causing the on/off condition. I would take the set or call a reputable repair person. Good luck

Try new lamp.

the blinking light signifies to a repair technician with capacitors or circuits are having an issue they can diagnose the problem via the amount of blinks in between pauses however it will require a technician and some specific tools and schematics to fix and it may be cheaper if its no longer under warranty to purchase a new one


Hope this helped

OH YES, IS THE OPTICAL UNIT BLOCK BAD, THE PART # IS A-1212387-A

Yes. If you hear a pop, the lamp probably exploded. You should pull it out and have a look. You user manual has some clear directions on the exact method of doing this. Don't be afraid of the instructions provided... the manufacture must "scare" you to cover their own ****. It's fairly easy, but you may need an allen key for this model. I hope this was helpful, best wishes.

HDMI is not a module. It is part of the small signal circuit board on most of these TVs. If it has an separate HDMI connector board (inside the cover), this is the most likely cause of the fault as a broken connector is 70% of all HDMI failures.
There is still over a thousand volts inside one of these flat panel sets. Be very careful not to void your OWN warranty...
You can order the part from Sony, BUT, you should know what you are doing. Just picking up the circuit board wrong can blow the board out before you even get to use it...

You need a lamp. This is a common symptom. I hope this helps. I have a tutorial on the function and failure of lamps, check it out if you like. It explains why your TV is doing this. I hope this was helpful.

Try these links to this site and they should tell you about the bulb and where to get them.

Google "Sony Service bulletin E29102171". I think you will have better results. I hope this was helpful.

Power Supply board is dead.Replaced the power supply board.Tries these Websites Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement,will get the power back.

You need an optical block. PN: A-1132-202-A. Part is very expensive with a $1500 core charge. Consider replacing the TV. Sorry, this is will eventually happen to all Rear Projection LCD televisions. The UV light emitted from the projection lamp destroys the Blue LCD panel first (shorter wave length), then the Green then the Red. The panels are not servicable, the entire unit must be changed. I hope this helps... it will save you a $100+ service call fee anyway.

Your thermal fuse has popped and needs replaced. This TV has a service bulletin regarding this issue. You should contact Sony for the replacement part/kit.

Hi,
It is symptom of weak lamp in tv that need to be replaced.
Replace lamp in your tv to fix this issue. Lamp replacement is easy and would be written in user manual.
Let me know if you have additional question.
Thanks.

Hi there

It is definatley a bulb issue. These are the symptoms of a dying bulb. You made the right call to order a new one!

Order a new bulb, easy to replace, just read the manual. In the meantime, go into Settings and change the Power to Power Saving, instead of Standard. Your bulb will work fine until the new one arrives.

It may be a 'security' type with a center post; mfr.s love to use these and they only need one to keep you out unless you are equipped. Use a mirror and light to confirm.

you may have signed up for the free trial--this is a paying question--confirm model number and tell me what the set is doing and not doing?

Same thing happened to me. If you shut it right down and then start it back up do you get 5 red flashes? if so then what I did was replace the lamp as it was real old. This took care of it.

Hi,
You need Hex Key to remove hex screw on left side of lamp then take out lamp.
Sony original lamp is supplied with hex key, please check lamp box.
If you do not have hex key, try small size flat screw driver to remove hex screw as flat screw driver could fit into hex screw.
Following exploded view shows how to remove that screw with hex key.
Hope this info will help you.
Thanks.
