Red light flashing means it can't dectect lamp housing. you can try and take it out (door on side of TV to the right hand side) and reinsert. But it probably means your lamp has blown. Replacement xl-2400 lamp is east to replace. Search ebay to buy one (about £100) and youtube has a video showing how to do it.

I have sony lcd hd ready 50inch rear projector tv model number KDF-E50A12U tv comes on after couple minuets tv clicks off to stand by then red light in stand by flashs 3 times gos back to green repets


Hello
Three blinks of standby light to Sony TVs indicates that the regulated voltage output from power regulator board is above thatn normal. The problem is with its power supply regulator board. Replace all the electrolytic cpacitors on that board with new ones. Replace all of them including small and large ones, at one time. OK.

Hi,
If its Sony KDF-E50A12U TV then its problem of weak lamp in TV that will be replaced and problem will be fixed. Lamp light on TV front will lit in case lamp is dead or broken but current symptom shows Lamp is not either dead or broken yet it got weak in result and causing problem.
Lamp replacement is easy and would be written in user manual.
Please but Sony original lamp for TV safety.
Let me know if you have additional question.
Thanks.

I have a KDF-E50A12U Sony TV it won't turn on and keeps Flashing red twice, no other lights are on, just the stand by continually flashing twice.


Two blinks - B+ over current protection (OCP), unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits.

Problem for Sony Grand WEGA KDF-55WF655. Hello,


5 times Red LED blinks means Lamp Driver Error. (KDF-55WF655)
2 possible reasons, either Lamp is gone or Ballast Supply got bad.
Replace lamp first, in most cases it solved the problem.
How old is this TV and did you replaced lamp recently?
Thanks.
