I have a Power Supply Unit in Westinghouse SK-26H240S TV.
TV had no power prior to disassembly. This TV has the Delta DPS-210EP-2 power supply. I appear to have proper voltage on high side, but i am not getting 24v; 12v; 5v, and 5VSB on secondary side output. The Bridge Rectifier is putting out 53V DC. The filter caps have been replaced on PSU.

Replace caps on power supply (15) caps. Voltages are all there but no picture.
You did not mention if you had sound; if you do, then the inverter for the backlight or the backlight CCFL has failed. The inverter is often on a separate board since these are often outsourced. ...

I have A Samsung 52 inch LCD TV model #LN52A580P6FXZA. The relay clicks at A random rate, there is A red light that flashes steady. It will not power up. All my standby voltages coming from the power supply are present as well as the run voltages. Power supply on voltage is present, inverter on voltage is present, occasionally, it will give A loud high pitched squeal. It never comes on. Any help would be appreciated.

Like yourself i have replaced 4 x 1000uF 10v caps (high temp) as the were distorted at the top. However my Samsung LE40R8 is exhibiting the same problem......Clicking noise and red LED going on and off. I was convinced this would cure the fault, having a basic knowledge of switch mode power supplies.
Which voltage did you use for the caps? I hope not the same. ...

Tv won't turn on. replaced bad caps and after some testing it turned out that the power supply board wasn't giving the supposed voltages.
This problem is not easily to be solved.Tries to changes all the capacitors components even if u think is good around the bad capacitors surrounding area.After that,if u still have the same problems.This problem could be any high voltage components p ...

Vizio VO370M will not power on. Vizio log stays yellow when power button pushed. Problem occurred following lightning storm, so suspecting the PS, but not certain. No physical damage apparent to either the PS or mainboard (fuse is good, no bulging/leaking caps, no burned spots, etc.). When testing PS, 5v connectors supply good 5.3v. 12v connectors have no power, but not certain if they always supply power or only when switched on. Is this more likely to be the PS or the mainboard? Would r

I have a TH50PX60U with the red light flashing 10 times. I went through the diagnostic flow chart to where it said replace the PA and DG boards. I replaced both and still have the 10 flashing lights. SInce that flow chart didn't seem to work I started checking the feeds from the power supply. I noticed on the PA10 that as soon as I plugged in the AC, the voltage read 15V. Then the voltage started dropping fast and went down to zero. Is this normal or should the voltage remain at a cons

I need detailed schematics with wire codes and values for diagnosing problems I am having with a Westinghouse SK-26h520s. The original problem was a dead machine, no indicator light so no power, replaced power supply now have indicator light but no sound or backlight, figured bad main board. Replaced board, made no difference. Any information, help or schematics with points and corresponding values to test with a volt ohm meter would be greatly appreciated

I have an element TV with a MLT070A power supply board. I'm not an electrical guy, but a technician came out and showed me the bulged caps and said that was what's wrong with the TV. He said he couldn't get replacement parts (I think the whole circuit board)but maybe the bulged cap components could be replaced by someone. I don't want to junk this TV and wonder what I should/could do. They're going to send me a $350.00 check for the extended warranty I paid 650 for the TV and 150 for the Cir

I saw the fix for the blinking power light . I replaced all 8 caps on the power supply board and 2 on the input board. Now the power stays on but no image. The monitor reconises a signal from the computer but no display. What frequancy does the computer need to be set at.
Almost all monitors will accept a 60Hz signal at almost any resolution, however I suggest 1024 X 768 at 60Hz...then you can try higher frequencies such as 75 Hz or more after you have established that the unit is functional. ...

I have a Insignia NS-L32Q-10A that will not power on. Now power on light or standby. I have replaced the power supply already. All caps look good and fuses check OK. What next???
Ok, when you plug in the set, does the power light come on? Assuming you ordered a power supply in good working order, you may very well have a faulty main board. The power supply produces standby power that the main board uses to power the standby/p ...
