TX-L50B6B Failing to start up backlight flicker

[Loading.......]

Hi.

I have a Panasonic TX-L50B6B (Vestel, I beleive)

TV tries to start up, during this time the backlight will flicker every second or so
After a couple of flickers TV turns off and red light flashes every 4-5 seconds.

I have removed the back and gave a visual inspection and everything looks fine to me. This TV has a what I believe to be a Backlight Inverter Board, I unplugged this and applied power to set and the set still turns off after the same amount of time (without backlights obviously)
Having read a few threads it seams it may be a backlight problem which is why I unplugged the inverter as I thought no inverter would rule that out (happy to be proved wrong)

I have no real electrical background Knowledge but I am not a complete idiot and do realise what power is where and to be careful. I may further add that I try to repair all of my own household electrical items as I am a tight Git.

Thanks in Advance for any posts relating to this and I have came here as you guys helped me about 10yr ago, during the Samsung bad capacitor period.

Thanks Guys.

One blink of the power LED indicates a problem in the inverter circuit.

One there for 25+10, may be some cheaper, just stopped at first one I saw, don't know if it will fix but that's what 1 blink code comes up with. As always triple check to try to insure a match whenever buying a part, maybe check the resistors on the board with a multimeter, it may be a 50 cent fix rather than 35 pounds. https://www.ebay.co.uk/itm/INVERTER-...aSl:rk:26:pf:0

Hi NomoreSonys.

Thanks for the replies and suggestions.
After having a good look around the site and the net, it seems these are terrible for backlights going. I have read a few where the inverter board was replaced and problem stayed the same. I think I will strip out the boards and tip it as I never know what I will find in my job and I quite often come across TV’s.
My other TV is a 55 inch Logik (vestel) I repaired that by replacing a few diodes after reading a thread or two on here, it owes my about £1 which is just over $1 in today’s rates ��

Thanks again Friend and I will nip in every now and then to pick everybody’s brains.

Keep safe Pal and best wishes from the UK ����

These might respond well to the current mod. here where they switch out a couple resistors. https://www.youtube.com/watch?v=ogtfojsIZK8
