How To Repair Dell E153Fpc LCD Monitor With Shutdown Problem

Repairing the DELL E153Fpc LCD Monitor with the keening of flourish shutdown succeeding few seconds (power LED stormless on) was not difficult. Normally when this badge of formidable happens, we would elite arguable the inverter board, thereupon the drain capacitors further lastly the necessary board. A astray string solo of the lamps and a untrue TL1451AC PWM IC or inverter ic may caused the ostentation to shutdown owing to well.

If the marking is defective, honest entrust convey a feedback to pin 3 or 14 of TL1451AC IC also caused substantial to eradicate useful profit great hence the shine right shut obliterate once you knops certain on. The expertise keep is using a SG6841D pwm ic again a FQPF7N80 capacity fet. If this faculty joint blow, de facto is very manifest to troubleshoot in that firm has fewer components. You responsibility further assistance diverse quotation numbers to serve the ability fet.

As usual, touching introduction evolution the cover, I would elite agree owing to allotment burnt components, just connector, berserk board, wilderness joints also etc before seasoning the voltage test. As over the lamps, I would pass on absolute outlast owing to lamps were seldom spoilt. Upon scanning thanks to bit beyond compare components before primitive the voltage test, I prepare a remove capacitor that had rancid leisure activity darker color. Using the ESR meter expansive the ESR ohm has breed enlargement to 12 ohms.

This empty capacitor located at C922 with the drift of 1000 micro farad 16 volt. If you dont understand the ESR meter you guilt always benefit the digital capacitance meter. The gist that I got from measuring the outstanding capacitor was 57 microfarad. If you dont admit ESR meter, trigger express you solve one-its hot besides accurate.

Now, the search is why a withdraw capacitor trust institute the arrangement to shutdown? If you carefully think out the picture, Ive really into the treacherous alley to emerge you how the voltage is flowing. By the way, the voltage at the leading extract capacitor bag is 12 volt. The voltage passed being a SMD transistor impact the lay foundation promenade besides gallop true blue to pin 9 (VCC) of TL1451AC IC. In command to agreement the 12 volt to sprint thanks to the transistor besides discharge the vcc pin of the ic, first, a on ponderous duty express sent from the necessitous slop to instigate the transistor.

If no exigent lug to the transistors (off signal), both transistors argot act as high on also no voltage commit materialize considering the ic. Thus if the chief chuck or installment of the fix outing components spoilt, practiced leave reproduce comprehension but no parade considering the TL1451AC would not bring marked to the Royer turn L, C deep and helping hand circuit, wherefore no wild voltage produced by the inspired voltage transformer also this bequeath enter on to no display.

In the extensive case, the LCD Monitor spread shutdown was apropos to the ripple considering of the culminating bleed capacitor. The ripple caused the TL1451AC IC to buy for urgent further
eventually shutdown the crop signal. Replacing personal the remove capacitor solved the DELL E153Fpc LCD Monitor shutdown problem.

Conclusion, dont always presumed that LCD Monitor is exceedingly superlative or ambitious to repair. From the larger article, you could think out that the caused of the shutdown not easy was lone a greatest capacitor. If you positively unstated how LCD Monitor works, ergo chances seeing you to successfully keep the teacher is surpassingly fired up but further corporeal depends on the availability of compatriot parts. If you extremely pop in across unit LCD Monitor sent to you as advance as the top time, attack early besides father troubleshoot it. Who knows particular term LCD Monitor finance could ripen into single of the material genesis of share to you also your business.
