Hi when i connect my asus pc to my tv to show a powerpoint it works for about 10 mins then tv says no signal and counts down from 5 mins why is this what can i do?


check your tv settings for standby mode. It may be set for 10 minutes to turn off if there is no tv signal like a power saver feature. It may not recognize the computer as a signal input. If I put my tv on a channel with no signal, it will turn off automatically after a short time. The same happens if I have it in video mode for the vcr and if the vcr isn't playing, after a short time the tv will turn off.Good luck

NO POWER AT ALL


Hi
our tv set need to be serviced. Here are some tips:
1. Open main fuse. The fuse is clean but interrupted. You can try replacing it with one o the same value.
2. Fuse Blown or blackened. Short in the rectifier bridge or in the switching transistor. Out of the power supply: supply line rectifier (100/150V) shorted.

Tv wont turn on


Hi
Normally Grundig tv sets when stop working the standby light is on. If it is so the power supply is faulty. You should check DC supply voltage in pin 6 of SMPS IC TDA4605.. If no voltage in this pin, check the limiting resistor connected in series. If these parts are OK, check the supply line rectifier diode for short.

My Hitachi L42VC04UB replaced a failed power board .The television comes on and after a short time it shuts down and the standby light in the front of the television flashes blue and red .This happe


Well either the TV's main (or other) board overloads the power board and it shuts itself off or the power board itself shuts itself off for whatever reason or the main board shuts off for whatever reason.

With the setup you have I'd say it's probably going to be difficult to figure out which one it is.

You will want to have yet another board - either main or power - to eliminate one of the two most likely possibilities.

What did you do with the original power board?

If you keep it you can probably send it to us for repair....or if it's cheap enough just buy another one.

i don't think there's an easier and affordable way to narrow it down than using a third board.

I turn the monitor on and it cycles on and off every couple seconds. I can still turn it completely off, and if it goes to standby it seems to stay that way. It behaves this way whether or not there is a...


It sounds like dying power supply due to bad caps or shorts circuits in the power supply or in the backlight inverter circuits.

If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Short battery life when idle - Sanyo Xacti VPC-HD2000


Strange, mine lasts a very very very long time, but in a standby state (power on, just close the lcd lid). Have you tried to just keep it in the standby state? I will never turn it off unless I need to, like to change sd cards, because it is super quick to capture video and it does not kill the battery.
I have 2 of these dual cameras and John is quite right, the Sanyo HD2000 is not a "normal" camera, its quite abnormally exceptional and way ahead of its time! Having a f1.8 lens, 1/2.5" cmos, 1080p @ 60 FRAMES/second, really makes it not "Normal". You will need a better computer to process the crazy 1080p/60fps images.

Tv won't turn on?


The main power supply section is not working.
(standby supply is OK)
Common possibilities are:
- High-voltage section (flyback transformer) has failed
(happens sooner or later, about 8 years typical))
- CRT tube has failed overloading the supply
- Power surge has popped the power input circuit.
(Fuse, rectifier diodes, turn-on relay etc)
- One of a hundred of electrolytic capacitors has failed short overloading the supply. They dry out with age, are cheap to replace, but hard to find which one it is.
- Or any of many other possibilities.

In short, you need a experianced tech to troubleshoot this.
