Check the CPU fan RPMS if they fluctuate over a wide range or the fan makes a louder then normal noise then the fan is probably going bad.

Samsung pn42c450b1d will not power on... clicks.. used to click like 5 times now clicks 2 times and goes into standby. ordered a y sustain from shop jimmy and it did not fix the issue. power board is


At first review of your problem the first thought occurred to me is that it may be a bad main/power supply...not familiar with new tv's but wondered if it was a simple as replacing a wire or something. You have said you replaced the main board. At first I didn't think that was necessary but apparently it's a fairly common course of action. That seems like a lot for a faulty power switch...but there's more to it than I realized. I found this excellent youtube video with some expert instructions on how to resolve, hosted by shopjimmy.com; you have referred to this source & I'd suggest it's about the best that's out there to find solution to your situation...seems something isn't switching over right & the tv clicks several times then goes into standby...thereby have to replace the faulty ??? I'd say capacitor but now adays the composite of the boards are alot different. This video link is the best solution. I hope it helps https://www.youtube.com/watch?v=n54IurMvr6o

The power light is disapeared and some times it flactuates


Fluctuates means 'blinks'? How many times this standby/power light blinks at one time switch ON? Count it carefully. These blinks are fault indication, and known as blinking codes. From the number of blinks occur at one time switch ON; you can get an idea about the faulty circuit stage inside the TV. This will make repair easy.

Dishwasher won t turn off


As long as you have wired up correctly, your new board is faulty.
If you mean wont power down, as in the lights on the front wont turn off, these lights and the power switch itself are all part of the board.
Take it back for a warranty swap. Occasionally there is the odd faulty new part, there has be some unfortunate person to get them.

Frigidare gas oven wil not get up to tempature


Hello - Does it reach the temperature and then back down, or does it take too long to get to your set temperature? Either you have a faulty element or a bad communication error with the main control board.

Faulty Samsung lcd tv LE40R87BD


Prices continue to drop precipitously and a repair or replacement of the board is gonna be expensive. Better off with new set and new warranty.

you need to check first the power supply board whether the output supply 12-24vdc for the inverter board is stable and not flactuating..you can measure the output voltage with a multitester..you get a voltage output of 12-24 with the inverter board is connected or loaded to the system.be carefull of the high voltage at the inverter board..once the output is stable replace the inverter board or you can measure the output of the inverter be very carefull..the output range upto 500vac.be carefull..if the high voltage is stable replace the lamps...tnx and good luck..
