Re: le40m86bdx off and on
does it eventually stay on?
checked voltages?
apply a little heat to the main board near the shielded area, may not be the case here but sounds similar to what i've seen and experienced on these bordeaux models -
Re: le40m86bdx off and on
Its OK until it warms up then goes off and on every 30 seconds or so... I does not stay on .Last edited by karlpowell; 05-06-2014, 11:33 PM.Comment

I am testing an old LG L192WS-BN monitor I have that gives an image, but has a backlight issue. When you turn it on the backlight turns on 1 second and it turns off, turns on again, 1 second and it turns off and stays off. Using a flashlight I can see there's still an image.
I replaced a bulged cap on the main board, but made no difference. I also got another exact same model monitor that has a broken ccfl (the connector got ripped from the panel and the main screen connector is also broken so I can't use this panel to test), tried using the main board from this one, same issue.... -

good morning, I have a samsung UE55F8000SZ tv that turns on, shows the logo and turns off after 1-2 seconds.
This defect happens continuously, hearing the classic click of the relay every time.
Power supply board BN44-00636B
disconnecting the mains and lamps from the power board always causes the same problem.
Is it normal that without anything connected this power supply turns on and off cyclically?
any suggestions on what to check?
thanks in advance

Hi Badcaps,
I've had a friend discard a TH-65DX700Z Pansonic Viera Television and I've decided to have a go at repairing it. If possible could I please get some advice in terms of diagnosing the problem so I can purchase the appropriate parts for repair whether it be components, a repair kit or a replacement board. I am happy to post pictures if required.
TV Details:

Symptoms:
The television turns on and displays a picture then makes a clicking sound and turns off.
I haven't opened it up yet but... -
I have had these 70 watt high pressure sodium yard lights for many years now probably at least 15 years or more and there is a protection diode that after several years starts to go bad and when it does this it has momentarily shutting down the light and then a few minutes later it starts working again
This about the forth time I have fixed this one and you can tell if it the diode or not if it lights up and it only shuts down when the air conditioner turns on then it is the diode
If it cycling on and off constantly then it is the bulb itself that is the issue
