42PFL5405H Philips TV does not turn on. Red light blinking 3 times.

Hi, during normal use the TV (auto)switched off, and the standby red led started to blink 3 times at regular intervals. I suspect it may be due to broken power supply, as the day before we experienced some overlaods during a bad-weather night.

Do you guys have any advice on what I could check with limited equipments in order to avoid spending (in first instance) lots of money for a professional repair?

Answer this question I have this problem too

Is this a good question?

This is most likely a main power supply failure. It will be easiest to replace it, but you may be able to repair it. Remove and examine for blown capacitors and cold solders.

Do you know which is the byw98-200 diode in the power supply board ?

Gianco, post some images of your power board with your question. For that use this guide. You will at least need some sort of multimeter. Level 1 Error 3 is a 12V error, most likely coming from the power board. This error can be caused by a shortened diode on the power board. Look for something like D210 and see if it looks "odd". Of course you can always go and replace the complete power board.

If had the same Problem on my Philips 42PFL5405.

The Problem was a Schottky-Diod (D210) on the Power Supply Unit. After replacing the D210 (Type SB3200, 200V, 3A) the TV works fine again.

This is a know issue with this TV.

In my case it was really D210. As i got TV (42PFL5405H/12) to repair, diode was already changed and so i don’t know it it was origin part. I replaced it with same type (1N5402) and it worked only for 30 minutes. Then i replaced it with RGP30 diode and since then TV is working again. Both broken diodes showed about 10 Ohm of resistance in both directions.

Please leave a comment here if this information was of any use for you.

@alexnoname great to hear that my 5 year old answer was actually right. Glad it worked for you and thanks for posting your 'answer'

Hi! I got a SQ552.1E LA TV that blinked 3 times. This diode was shorted out, changing it fixed the problem. Thanks everyone!

Hi! Another 37PFL5504 fixed that blinked 3 times!! My original diode was SB3200, 0 ohm in every direction. I've used RGP30D. Thanks everyone!
