Samsung PN51F5300AF will not power on
OK Need some help. Plasma's just drive me nuts.
Got TV son said made a loud pop and went off with no power. Opened it up and found that the fuse was blown and part of the copper trace on the back of the board had burnt. Replaced PS with Ebay unit, now getting 5.3v standby and nothing on the PS ON. The main board LED flashes 5 times then nothing. If I disconnect the cable from the CN801 on the PS I do get 4.3v at the PS ON pin. Next was to replace the main board which I did but I get the exact same outcome. At the at the IR connection test points on the main board I get

Re: Insignia ns-pdp50hd-09 Blinking Codes?
OK Started to look into this set.
Voltage Tests on Y main board Samsung BN96-07132A (LJ92-01535A)
Spec ............ Actual
Va 57 57
Vs 204 204
Ve 96 95
Vsc -195 -50
Have Standby power but no change when power button depressed. The flashing LED's I saw are not from the power board but are on the Samsung LJ92-01531D Main Logic CTRL Board. 3 LED's come on when set plugged in. one in the center goes out and the other 2 flash continuously. Still Looking...

ns-pdp50hd-09 Blinking Codes?
Anybody out there have a list of the blink codes and what they mean.
I picked up a ns-pdp50hd-09 gonna tear into it this weekend. Right now all I can tell you is when plugged in it starts to light up the screen, then goes off. LED is blinking continuously. Code chart, Service manual would be helpful.
Thanks

LC401EM3F Color Convergence?
I know there is no such thing as convergence any more but it is the only way I can explain it. The Model doesn't have a Tcon just a connector from the Digital main board to the LVDS that's connected to the panel. I have replaced the Digital main board and ended up with the same results. I have put pressure on the tabs from the LVDS to the panel no change. The panel is a Samsung Lta400hm09 . Any thoughts on where to start looking Kinda stumped.
Thanks...Last edited by dhack61; 04-25-2015, 03:46 PM.

Re: Westinghouse SK-32H540S
LOL.... Yes that is true. I could spend another 40 bucks on this thing. Cheaper would be better...

Re: Westinghouse SK-32H540S
Well maybe somebody can help me with mine, Have the same problem
All voltages from PS correct, no signal voltage to BL_ON. No standby light but, I can press the power switch and the main blue light does come on.
Checked all VR's and they are fine and to spec.
So whats next in this process?

Re: Vizio E3D420vx No Standy Power. Why?
If your screen comes on then your fuse probably is ok.
There are several here with the same problem on Vizio e3d420's and 420's. I have the same problem with a 320. have not found a solution. You need to check the voltages coming off the power supply board with your meter. Pins 1-3 should be the standby 5.2V Voltage. Pins 8-10 should be 12v, pins 11-14... I have no idea. THose are the return voltages signals from Mainboard. I am searching for those.
For What its worth 7 out of 10 sets I have fix with no Standby light and good...

Re: RCA L37wd12
Don't have a camera charged but I do have the Schematic for the board. If you still need a picture let me know....

Re: RCA L37wd12
That's pretty much the same set on smaller. I am not getting the click to start the 120V on the main SMPS. You said the main board was out. do you mean the Scaler board?...

Re: RCA L37wd12
Here is a copy of the interconnect Dia from the service manual. Its marked L32wd12 but its the same for both sets.
The Voltage chart shows that 5.3v should be coming in to the scaler board.

RCA L37wd12
Having a problem with voltage drop going from SMPS 1W to the Scaler board. Unplugged from the scaler I have 5.3v standby on the SMPS 1w going out. As soon as I plug the scaler back up the standby voltage drops to 3.6.
Any Ideas?

Re: Acceptable Voltage Variance
Thanks for the info. I found a Ceramic Cap soldered on the back of the board that was reading infinite both ways. Its a 220pF 250v Guiess they used it to regulate the voltage down. Gonna replace it and see if that gives me my 5v without it getting 12.8v standby. thanks again...
