Top 20 Toymax Viore 42 in. Plasma TV Questions & Answers

Check high voltage circuit. This is near where the 120 volt cord is plugged in and a high voltage transformer, where there should be capacitor (or two). Check the voltage - should be 390 to 400 volts. If not less than 390, near to replace the capacitor.

Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electro-medical.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Sounds like main board fault. Contact any "Experienced" service technician, or, the authorized service center for Viore. Gopakumar Gopalan Google

The proper way to set flat screen tv's is opposite of old school CRT tv. First, find a movie with dark scenes and pause on a really dark part. Now set brightness only high enough to see some detail - no more. then go to a really bright scene and set contrast just high enough for good brightness. You may need to go back and forth a few times to get good setting.

There is something wrong with the voltages out [low voltages] from the main power regulator board. Check it. If you wish to get more details, check this site. http://electronicshelponline.blogspot.com/ Pull up previous posts by its left sidebar, or type in the brand name and model number to of your set, to its search box, and press 'Enter' or view it in Mosaic / Timeslide option.

replace the mainboard

Is this problem occurring while watching any channel or while playing any DVD?

check first at the sound set up menu might set to off. if the settings is ok and the speaker is also good, the cause is either bad amplifier circuit or sound processor at the main board. at this time you will need a trouble shooting.

I see so many here with no sound/no picture issues: ISSUES: 1. IF sound main fuse/s are good. 2. If no power or standby check main fuse, standby power supply and any signs of 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 the problem. 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 generic ones like Radio Shack). Many fuses are special even aside from amperage--Don't put 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 a standby power supply that runs 7/24 and a main supply (some are combined and some not. Here aside from checking fuses you want to examine all the filter caps on the power/standby to see if any are puffed up or buldged up in some fashion--I attach a photo of a good one---top should be silver metal and PERFECTLY flat and 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 runs 7/24 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 buy and 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 this photo.

Try going to their website and see if they have an update for your TV first. Usually, the update is saved on a flash drive and plugged into the TV to transfer the update. Be sure to PRINT the instructions !!

speakers switched off?volume on set or a box down or muted? check both the set and box.Does the set have normal sound when playing a DVD etc via the audio and video jacks on the rear or side?

You are going to love my answer ---- read the owner's manual. Not all the manufactures have the same procedure for such however it is usually addressable in the setup. I'm not familiar with the brand Toymax but I feel if you look on your remote control, you should locate a setup button. Reading the manual will tell you quickly how to do it. If you do not have the manual, do a search for "owner's manual Toymax Viore 42" plasma TV" at Sears.com web site You will need your model number to get the correct one. That will solve your problem.

Having to unplug it means the microprocessor in the set is locking up for some reason.more info:Audio but nopictureThis is acommon issue in many LCD or Plasma sets and it does not have a common solution.In most cases you need to first check for missing voltages on the power supply board and for damaged caps there. If good voltages exist then look elsewhere.LCD (not projection) sets often use a back light to provide the light source for the screen unit (display panel) so confirming the voltage for those is first-if back lights are used but not on it is either no voltage, not being turned on by the set, or bad light unit/s.In these sets there are also boards that "Drive" the panel itself. Usually the set will use two boards (some combine both into one large board---names vary but are Inverters, Y-boards (Y means video) T-con boards etc. Usually in this case only one half of the screen will be black but it is possible for it to cause a total loss of brightness also.Plasma sets are similar to some degree but with no back light in most cases.Trouble shooting can be tedious and expensive-Taking one of these sets apart requires some skill as one wrong move and the Display panel can be instantly damaged which is fatal from a repair cost point of view.Other possible solutions include but are not limited to physical problems---loose plugs or connections (look for any plugs held down with tape where they plug into a board). A lot of people with problems play the guessing game-buy and try a board after research which can get expensive and may not fix the set---gamble or not?I have seen sets where every single board was replaced and set still did not have a picture-means display panel is the problem.The problem can even be the "main" board in some cases -it controls the communication with the panel and if faulty can cause issues.Aside from checking voltages, connections etc. there are afew other considerations---The problem can be the display panel itself---Part cost for that is more than the set cost when new.The panel connects to the boards that drive it with either a multi-pin conventional plug or a RIBBON CABLE.The worst case is the problem is a ribbon cable etc. bad or damaged INSIDE the panel where it cannot be got at.That means if the case set would cost too much to repair.The connectors where the cable attaches outside of thepanel can also develop dirty or loose connections.Fans in units that use them can be an issue if dirty or not moving.As you can see (or not if no brightness) the problem sounds simple but has many possible different causes.Let me know if you have questions as I am here to try to help.SD TECH

Read the following:http://blog.coppelltvrepair.com/2011/02/hp-pl4260n-suddenly-lost-picture-how-to.htmlDifferent TV, but most likely same problem and, in fact, quite possibly literally the same boards, so maybe practically the same TV.Can't be sure since you haven't posted the model of your Viore.If you have specific questions, please always include the model number in the question...the model is on a sticker at the back of the TV, right after or below the words "MODEL:" :-)

the power board is under excessive load there is a short circuit component on the secondary side of the power supply you will need a multimeter to locate the faulty part and a soldering iron to replace it

Discoloration is ussually a prolem with the sustain boards on your TV. Your TV have two sustain boards they are located on the left and the right ends of your tv. I t is hard to tell which one is bad so you might want to change both of them it is recommended anyway. You can get parts at www.interliquidparts.com

a dull picture is usualy caused by the z-sustain board but i have known the y-sustain give the same symptom sorry cant be any more help these boards can run quite expensive try getting used ones from ebay i would go for the z-sus first

Hi Your sustain board is bad. The TV has two of these and it could be one or both. Most likelly it's the y-sus.You can get parts at www.interliquidparts.com
