Vizio P42HDTV10A flickering

Hello everyone,
Our plasma started "flickering". I will try to describe it. The picture is faded and blurry in the background of blinking or flickering. If I disconnect the cable box or change the input, the problem is still there. When there is no source and the tv is just on the blinking is there and the picture is a bunch of red, blue green dots, probably each pixel. I have the TV back off and ready. Any help would be much appreciated. Vizio tech support said I need a new "main" board. I do not probe much after that. Would you agree? If agreed, which baord is it? Is there a reputable place to get the part?

    I have seen a few similar problems within the forums with descriptions of "sparkles". I have yet to see one with a solution yet.

    I have a problem with flickering on my 47" Vizio TV(Gallevia) and it is terrible. It is hard to describe because it comes in different forms and sizes. Its amazing that you don't see this type of problem on the shelf at the store. I have had the main board replace. However, the problem still persists. I have also had issues with the infamous green screen effect.

    My TV suddenly became faded and then flickered--it's like a flashbulb going off. I can watch it, sounds fine but it's not pleasant. Very washed out, black smudge here and there and the flashbulb/lightening thing too. It's only three years old, a 50HDM Vizio. Any ideas appreciated!!!!

try to adjust Vs & Vsc within 5% of their spec on the power supply board when you notice the problem.

SOURCE: red pixels

This prob shows up often in this set. To solve , remove the 4,784 screws from the rear cover. Plug in and connect the set. Operate until red dots appear. Locate the V_SET-UP control on the Y-SUS board ( the one on the right from the rear ) . VERY CAREFULLY and SLOWLY adjust till dots dissapear and STOP. This adjustment is VERY sesitive and requires only the slightest adjustment with a small insulated screwdiver and a steady hand. BE WARNED ... there are high voltages and high peak pulses on these boards. Not all heat sinks are grounded... some are quite lively. Dont touch anything else, unplug the set and carefully replace the cover. Good Luck..

SOURCE: plasma tv has no picture but green led is on

Try unplugging the TV for a few minutes (discharges the ballast/ps) then plug in and attempt to power on. I have the 42P Vizio over two years old and ran into the same problem a few times. First thought was a power supply issue, but the unplugging trick worked. Good luck.

SOURCE: Picture problem with Maxent Plasma MX-42HPM20

Very common problem on these sets caused by bad surface mount caps. Check on ebay for a repair kit it's the only place I know where one exists.

I have this problem too. I have had a technician over to service it twice already and I picked up on a few things he did to fix it. Here is what I learned. the raining pixels has to do with the timing in the circuit boards. Basically telling them when to turn on and off. I would only recomend this solution if you are technically inclined. Remove the back from your tv on the left upper quadrant you should see a small gray dial with marks that a Philips screw driver would fit it. There are three or four of these on the boards scatter across the tv. Each on corresponds to the colors firing in sequence. Take your Philips and turn it to either extream. You should see a your screen go crazy with whatever color corresponds to the dial. Then ever so slowly turn the dial undtil you don't see any more flickering. Do that with each dial and you should be able to get rid of most of the flickering. on the right side of the there is a panel underneath the support bar with orange adjuster. I don't know what they do but they also help reduce the flickering. A word of caution. If you can use something non metallic to adjust these dials. There is a small metal lip to keep the dial from turning too far. If your screw driver touches it. It will fry the dial and your screen will blink red/yellow or blue. and you will have to buy a new board. Luckily they are only about 30 bucks, but I learned the hard way.

Plasma TV colour going off


That could be the Z board, but most likely the sustain and upper/lower buffer boards. The brightness is found in the Z board. Try to find a repair shop to repair on the component level because the cost of new boards out weighs the cost of replacement.

When watching dvd having showing or fade background


yes it can be down to signal degradation especially via scart lead, make sure you use a decent scart if you buy an expensive one you can tell the difference. Run a cable from your sky digibox direct to your tv to see if the picture improves.

Flickering dots


The symptom you described is called diffusion. A simple alignment, normally in the power supply takes care of this problem. For the nearest Authorized Service Center near you contact Toshiba online at: http://webmail.tacp.com/service/servcntr.nsf/$$Search?OpenForm Hope this helps
