Samsung un50h5203af
hi all I have a Samsung UN50H5203AF TV when plugged in , the back light just flashes on/off cycling..
I've opened it up no swollen caps
The power supply board number is L50HF_EHS at CNL802 pin1 and pin2 measures 381.7 vDC with the connector unplugged when plugged in the voltage fluctuated from 90v to 110v (black probe at ground by power plug red probe at pin 1 or 2).
Can anyone tell me how to proceed next?
Thanks,
Jason... -
Re: Insignia NS-32lcd washed out colors
I was not able to fix it as other connector cables the plastic had endured some heat and the plastic crumbled on the connectors leaving the pins . I did not feel comfortable just putting the pins on there with no insulation between them and wasn't able to get another set of cables . so I tore it down for parts an diseminated them.

Re: Insignia NS-32lcd washed out colors
Putting it back together . The flat cable 8pin goes from the power supply to the invertor board about 15in maybe one end the plastic crumbled off so it's bare conductors I would like to find a replacement because I really don't want to put it back like that.
Any suggestions where I might find one?
Thanks,

Re: Baldwin Piano ccfl display
Laptop LCD invertor can that be used to test a ccfl?
It is from a Dell Latitude d610.

Re: Baldwin Piano ccfl display
Never tore one apart, guess I will see how hard it is on an old laptop screen when I get the invertor out.
Thanks for the link,

Re: Insignia NS-32lcd washed out colors
At the time I hadn't uncovered the Tcon board and what you linked didn't look like anything I could see. Budm told me where it was and once I uncovered it , it was gone.
What is the difference between v320b1-l01-c(what I have)
and V320B1-C03(what you linked to)?
Thanks for your help,

Re: Baldwin Piano ccfl display
All I need to do is make sure it will light up, if it doesn't then it's bad and needs replacement

Re: Baldwin Piano ccfl display
It'll be a few days before I can get back to it. But when i do I want to be able to test the ccfl.
Here is the datasheet on the screen

I'm thinking I could use a laptop invertor board just to test the CCFL would that be correct?
Thanks,

Baldwin Piano ccfl display
I have a baldwin Electric grand piano the display is not working.
[URL="http://www.shema.ru/cd/us/2/data/ps2500.pdf"]http://www.shema.ru/cd/us/2/data/ps2500.pdf[/URL]
The DC/AC convertor board had the fuse, C2 , q1 and q2 were burnt. I replaced them and still no light.
Would there be an easy way to test the ccfl to see if it is ok?replacements are a $100plus.
Thanks,

Re: Insignia NS-32lcd washed out colors
Yes and it was made in 2004. It was recapped in maybe 2011. I'll open it up tonight and take pics of the TCON board.

Insignia NS-32lcd washed out colors
I have a Insignia NS-32lcd tv I recapped about 6years ago dumpster salvage.
Recently the colors started looking washed out. Tried several different source inputs, cable, antenna, vcr, etc and they all looked washed out. Picture is sharp but colors faded. Any suggestions on what to possibly look at?
Thanks,

Seiki SE47fy19 no hdmi
Hi all i was given a Seiki SE47fy19.
I have tested all inputs and they all work except HDMI. All 3 ports just show no input. Is there anything I can do short of using it as it or replacing the input board?
Thanks,

Re: Westinghouse ew40t4fw
So are they generally easy to repair the open circuits?
What about the 485v What would cause it to be so high?
?Thanks,

Re: Westinghouse ew40t4fw
I did verify with a second meter. Now on the large board there are 4 screws 2 with a tear drop shaped washer under the screw. Black probe connected to that for ground, red probe to cn1 is how I'm getting 485 vdc and my other measurements.
I can try with the simpson analog meter to verify it also and will update, let me know if I need to choose another location for ground.
Thanks for your help,

Re: Westinghouse ew40t4fw
On the +12 12.22
+5 5.21
on/off 4.59 on
Lower connector
adj 2.59
BL-on 2.90
cn1 When I turn on gets 485vdc when w logo shows and dissappears voltage starts dropping
cn2 265vdc logo shows then voltage starts dropping.
When I unplugged cn1 and 2 voltages stay up.
Any help would be greatly appreciated.
