Check power cables to dvd and hd. voltages should be 12v,gnd,gnd,5V with and without load. if voltages drops with load then fault is probably with caps. I changed one cap when voltage dropped in dvd powercable(5V). cost only 0,50€ to fix powerboard. there is a high risk for electrical shock so if youre not familiar with electrical devices and dont know how to perform these checking operations and so on... then PLEASE take your unit for professional

My standby power button stays solid red and will not turn green. No display or sound.


Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary. /

Control panel is not responding


Most likely, if power *is getting to the unit*, (there are lights lit on the washer), then the culprit will be a shorted user interface board(control panel). This is a fairly common type of issue with dishwashers. The soft-touch buttons or the touch panel has a shorted button or area(depending on the type you have) and nothing else will function because the unit thinks you're still pressing a control button. Also, a VERY common cause of this issue, aside from moisture or bugs, is a power outage damaging the console when power is restored due to a surge. After an outage where damage occurs, the symptoms don't usually start for about 3-4 weeks after due to damaged chips on the board starting to fail.

I have a Kurzweil pc88. The unit function but the power board 7805 voltage regulator overheats and eventually shuts down after 7-8 minutes. All else appears functional. Any suggestions?


Try changing out regulator . Check voltage output and resistors are a good culprit in these cases. Are you sure the rectifiers are doing there job ?

I have a rca projection 52 inch 3 lenses power comes on but picture not .... is there bulb or some thing i need to find and replace or fuse some where


Hi Buddy
there are a few things that can cause this symptom but we need to go back and regroup .
let's go at this from a technical stand point .
when you plug the unit in and turn it on what do you see the led's in the area of the power button and pay close attention to the blinks if there are any . then we can try to get you on the right track .
also id guess you already have the back of the set off ?
if so on the large board on your left side looking at it from the rear of the unit . there are some caps that we should look at cp150 cp130 cp120 if i remember correctly . what your looking for is the bulged cap that some many hit on and true its a problem but if it hadn't been for caps failing they may never have fixed them .
one word of caution is not to push the power button excessive at this point if there is a loss of deflection you may well damage one of the crt's or picture tubes this unit has a red crt blue and green and they provide the screen lighting and video you see .
with you behind the set perhaps you could have some one push the power button and listen to that high voltage transformer on the left side board it has a red wire coming off of it . and be cautious there is possible shock hazard there .
and if you have access to the caps i would change those caps right off the start as they are most likley defective as well as other possibility then let me know what you find and il see what i can do to assist you

Power button lit and will not respond. No other controls respond.


In most of the computer board controlled appliances in the house today, A good reboot will restore the default settings.
Unplug the washer and let it sit for about 5 minutes to allow the charges to dissipate off of the electronic boards. (capacitors retain a charge for memory).
During this time check to see if the buttons are stuck in the down position. Most of todays buttons are magnetic induction (a magnet completes the circuit when pressed) so the processor may be locked up or confused. Removing power restores the basic instructions.
Another cause/fault my be a safety related issue. The unit will not power on or turn on unless certain conditions are met. The door properly closed, Something in the drum, level... that kind of thing.
Good luck.

Power light comes on but not working


First you need to determine how many blinks you are getting when you try to power on the laptop. Check the blinking codes below and reason behind that for HP Compaq laptops Blinking battery power LED Battery Insufficient charge on the battery Blink: 1 - Caps Lock/Num Lock - CPU CPU not functional Blink: 2 - Caps Lock/Num Lock - BIOS BIOS corruption failure Blink: 3 - Caps Lock/Num Lock - Memory Module error not functional Blink: 4 - Caps Lock/Num Lock - Graphics Graphics controller not functional Blink: 5 - Caps Lock/Num Lock - System board General system board failure Blink: 6 - Caps Lock/Num Lock - BIOS BIOS authentication failure You need to first Remove the memory module (RAM)- Try to power on the laptop ? then again reset it and try to power on. Check whether it is coming on or not. try the same procedure with Hard drive. If laptop is getting power on after removing one of the device then we can be sure that that particular device is faulty and we can change that then? Let me know if you find any difficulties doing this.. I hope this will help you to get it work. Plz vote for me..Dreamkam
