Question about Sony KDF-E42A10 42 in. LCD Television

1 Answer

KF-WE42 Indicator flashes red.

As per the manual there is self-diagnosis function forthat model TV and the number of times the indicator flashes red indicates the possible causes. Suggestion is to inform the Sony service center about the number of times the indicator flashed.
I counted six times between 3 sec intervals but still have no idea/solution how to power up the TV.

Try leaving the TV unpugged for 30 minutes so the TV can reset itself.
If that doesn't work, most likely the TV has a power supply related problem.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you flashing red light codes, circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.

Sony TV LED & Blinking Codes - What Does It Mean When Standby/Timer Light Flashes

Sony has provided a "self-diagnosis function" with your TV, that in the case of abnormalities or problems the LED or red blinking light on the Timer/Standby indicator flashes a number of times to indicate the issue.
when there is trouble with your Sony Television set -- it indicates the issue in either the diagnostic mode, or even more commonly by flashing a series of LED blinks or flashes on the front of your television. Each set or frequency of the blinks indicates a very specific problem with the television itself.
Sorry but unless you may be able to repair the television set yourself , please call a local repair shop to the have a repairman sent out,,

Sony LCD Model KF-60WE610 lamp was replaced and then it shortly after stopped turning on. Blinks Green 6 times then Red 6 times Please help!


For Sony Model KF-60WE610, KF-50WE610, and KF-42WE610, the Diagnostic Code of power light indicator flashing 6 times green, then flashing 6 times red (6 red etc), means you need to replace part number A-1302-272A G1 BOARD, COMPLETE. See Sony Service Manual, 4. Chasis-1 at part Ref no. 103. The Power Board sits vertically in two slots on the left side of the electronics board. 4 wire connectors to remove when replacing. This component fits all 3 KF models listed above.

My Sony Grand Wega picture went out & red stand by light flashes 3 times then pause & flashes 3 times again. What is wrong???


the reason the tv flashes its l.e.d is to tell you there is a major fault in the main circuit board (pcb) and needs to be fixed its not a fuse it not a reset problem its a dynamic fault that could be from a bad resistor to a downed capacitor if you have knowledge of these components then check them using a multimeter find the faulty parts and replace accordingly. but if you have no idea then it will need to go into the repair shop. a lot of our customers ask us if the unit (tv) etc after being fixed will be any good or should they buy a new one. a good tech will fix the unit and in most cases it will be tweeked and work better but always get a quote up front and hold them to it within $50.00


best of luck to you

General Troubleshooting Information
How to Retrieve a DTC

The Climate Control Unit has a self-diagnosis function. To run the self-diagnosis function, do the following:
1. Turn the ignition switch OFF.
2. Tu rn the fan switch OFF, the temperature control dial to MaxCool (60.F or 18.C), and the mode control dial to Vent.
3, Turn the ignition switch ON (ll),then press and hold the recirculation control switch. Within lO seconds while holding the switch down, press the rear window defogger switch five times. The recirculation indicator blinks two times and the A/C indicator comes on, then the self-diagnosis will begin. About 15 seconds later, the self diagnosis will finish and the Ay'C indicator goes off. lf there is any problem in the system after finished self diagnosis, the recirculation indicator will blink the Diagnostic Trouble Code (DTC) 1 through 13. When problems in the evaporator temperature sensor circuit are detected (codes 14 and t5), the A/C indicator will blink the DTC. lf no DTCs are found. the indicator will not blink.
