It was working on standby when I use remote to turn on it didnot work I unplug from mains and after few minuets I pluged in now nothing happen even the red light is not showing

Hi,

Please remove all extra devices (ie video game console, dvd platyer) and turn on your tv again. If not working, please attempt to change channels on your remote or remotes.

If still not working, please setup the tv like you did when you first bought it. Thank you.

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. Surf the site with patience. 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.

you either have a faulty power supply or faulty main board. Vizio power supplies on the older sets are pretty decent. It's usually the main boards that go. These older main boards tend to be pricey so it may be better to buy a new set.

First if you have not tried it--unplug set and or cable or sat box and reboot them--in first part of your question you mention only on off on remote works--indicates a lock up of the micro.

some general info:

I see so many here with no sound/nopicture issues:

ISSUES:

1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.

Depending on the brand and MODEL number here is what I think happened.

All TV sets have a Standby power supply. It runs all the time even if set is off but plugged in.

It supplies among other things the power (usually less then 12 volts DC to run the remote circuitry---It usually is not fuse protected so if a strike hit nearby it may have come in via the power cord.

Trouble is almost certain to be in the standby supply.

I got same issue. Solution is to buy a efergy standby eliminator plug so it can respond to the On/Off signal by cutting off and restoring mains power

The Integra DPC-8.5 changer (as opposed to the DPS-8.3 single-play unit -- not sure which you have, as you mention DPS-8.5, a non-existent model) and most of the integra line of players, will sometimes be thrown into brainlock by out-of-step shutoffs. They will usually respond to the Integra/Onkyo instruction manual's directions to turn it off (you're already done that), then unplug the power cord from the back of the machine, wait a few seconds (make it 30 to be safe), then plug it back in and turn it on via the standby switch. The screen should display its welcome message, cycle through startup, and being working again. It is very much like rebooting a PC. In fact there is little difference.

If this doesn't work then something has gone wrong inside and probably has nothing to do with your shutdown method on the way out the door. These things do happen. Hopefully by now you've already figured this out. If not, give it a try. It usually works.

Hi I have jamo Dvr50 system and it has been frozen since yesterday. I have power down few times but nothing is happening. It comes on and panel lights up but that is all.

You have defective caps on the power supply pcb which needs replaced.the top of the caps will look like they have been bubbled up..change all of those that look like that.

I took your advice I unpluged the unit then held the power button in then pluged it back into power outlet the unit came on. There is one thing I might add I had to do it twice before the unit came on. Now how long will it work? Who knows
