Most likely the power supply board needs to be replaced.

If you don't know what you're doing, DON'T OPEN THE TV UP TO FIX IT, THERE ARE HAZARDOUS VOLTAGES ON THE POWER SUPPLY BOARD, EVEN WEEKS AFTER THE TV IS UNPLUGGED!

If you don't know how to do it yourself, find some local Electronic repair shops, get quotes, try to find reviews on the shops.

My casio protrek 2500t watch is in power saving mode but even after keeping in dark for hours between 10pm and 6 am the display does not go off.Please help.


I own the same PRW-2500-1A (all black).Check if under the hours reading, PS appears.If yes,power saving function is activated.
Normally, Power Saving Function is enabled automatically (if activated) if the watch stays in complete dark for sometime.If after a couple of hours in the dark the watch comes suddenly under bright light,the display goes on immediately.Hour interval (10pm-6am) has nothing to do with Power Saver.
Try the following:
a)Deactivate and reactivate (or vice versa) the PS.
b)Leave the watch in the dark for a couple of hours .Then,still in the dark,try,using a very low power light (just that you can,barely read) to check if display is blank.If not you may have a problem with the light sensor found at the bottom of the display.Will be a very rare case but you have to take the watch to a CASIO authorized service.

RCA Model# LED32B30RQD Tv has sound no picture. Picture went black while i was watching it. Can see image in dark room with flash light. TV has power supply board, video board. Start with video board?


That board right in the middle is the power board and it powers the LED backlights. This is a common failure on this model and the board is not in stock in most places.

Watch does not glow in the dark


Is it suppose to glow in the dark? You don't give any information about the watch, make, model, age. If it was suppose to glow in the dark and it is old, that function may have deteriorated beyond normal limits.

Have yo sat your watch in strong sunlight for several hours then checked the glow in the dark feature? Is this a watch that glows as the result of a light in the watch powered by a battery that may be weak?

I suggest you take your watch to a jeweler in your area and have it gone over to assure proper operation.

Thank you for your interest in FixYa.com

Tv has died


When the TV is on, if you look at the screen and can see dark images, then you will need to replace both the inverters. The inverters drive/power the back light inside the LCD to show the images. You may have to try and different channels and or inputs to truly see if you can see dark images while the TV is on. If you are hearing audio from a channel or an input then you should be able to see the dark images if just the inverters are bad.
If the screen is dead black without any dark images, then typically your LCD screen/module is bad.
If the TV powers up (power supply is good), you have audio and the remote will work with the TV (the main board is good), the only parts left is the inverters or the LCD screen/module.
I can get you LG part numbers if you need them.

Ultravision image dark


Good Day, tfarmer;

Since you have replaced the lamp, which is the normal cause for a dark picture. Have you checked your video settings?

The brightness level should be set at about 55 to 60%, the contrast should be set at about 90% and the video temp should be at normal or high.

If all these are set about this way, then I would think that the light engine might be going bad.

Good Luck, big IRISH.

NEc plasmasync 42mp2 - dark screen and in the top few pixels show the image


It's either the Y-main or logic board but you would need to do some extensive testing to know for certain which one... It's not the screen..
I would strongly recommend you take it into a shop and have a Tech test it and give you an estimate..

Problem with picture it is very dark


hi,
Just a guess,under the power button, inside the the flip[ down cover is a light dimmer,you can turn this on and off,in advanced settings under video,a flash light will trigger the sensor to see if it works the dimmer,if not it could be that circuit or your power supply needs work,I hope this helps!
