Hey guess what?! After Costco shafted me good, told me to get lost, and slammed the concierge phone down, I called Vizio. THIS TV HAS A LIFETIME WARRANTY ON IT NOW!! They will fix/replace it at their expense! After a 5 minute call to their customer service they arranged the repair order. Vizio knows that this set is a lemon and they are actually owning up to it. The gentleman told me that this set now carries a Lifetime warranty on parts (to exclude a shattered screen of course) and labor! The repairman is going to come this way in the next week or so and I'll update you on what he says. So to all out there with problems on this set: CALL VIZIO AND GET READY FOR A BREATH OF FRESH AIR!

SOURCE: Short circuit on the "Y" sustain board

The problem is heat!!! If the tv has fans they should be checked for normal operation,although on the early samsung models there were none, and the problem is that the panel drive buffers are getting to hot due to inadequate cooling. This is most apperent when tv is mounted to close to the wall, also external fan blowing on the rear left side will dissapate the heat. It is a problem on early Samsung and Electrograph 42 " plasma models. Hope this helps.

Tv just went off


Sanyo DP50747 has about a gazillian completely different implementations.

Some of them have Samsung boards inside, some have LG boards inside and yet another one has Panasonic boards inside.

Samung sets have known problem with the YSUS sustain being killed by a failing buffer board, the LG ones with the YSUS and ZSUS sustain boards, the Panasonic ones with the power board, which reminds me the previous two also have known issues with the power, but not nearly as common as with the sustain/buffers.

Main board is also known to cause issues in the Panasonic-driven models.

All in all it is essential to know which chassis (model) you have in order to provide any meaningful help.

You can also try searching at www.coppelltvrepair.com/search for various repairs or replacements offerred for DP50747.

I was watching my hitachi plasma tv when the power went off it wont turn on no clicking or any noisy


If you still have led lit on front panel, then you know main ac fuse is good. Check fuses on y sustain board and z sustain board and there will be other fuses in the secondary of the power supply board.
check those also.

I replaced the module on YSUS board and replaced the FS2 fuse on hp cptoh-0602 plazma tv. TV worked great for about 2 hrs of usage time. however, while i was changing the channal few days later since...


Usually, when you replace Y-sustain board, for older plasma, they suggest to replace both Ydrive board (up and low). And sometimes, Z-sustaint.

Im not sure your are an expertise in this matter so be very careful when you open a TV because hasardous voltages can kill you in the worst escenario.

If you are not, don't work on your TV. It will be your sole responsibility.

Check ships on Y drive board (both board are installed on the right side of Y-sustain. They have square black ships that used to get bad. If they don't have aluminum cooler on them, you can see if they are burned or have holes on them. Old plasmas use to have issues with those boards. Before you installed the Y Sustain you should check Ydrive boards. Maybe you damage the Y Sustain because the Y drives weren't good.

Try to replace the fuse, disconnect the Ydrive from Y Sustain, turn on TV and check for voltages on Y sustain (panel has a sticker with each voltage). Hope you didn't damage Y sustain and can find Ydrive board to fix your TV.

And REMEMBER, you can kill yourself when you work on TVs.

Bought a samsung 42' 4000 series tv, its less than 2 years old & the picture went bad looks worse than a really old tube tv watching an old VHS. contacted samsung-they don't care, referred me to a tv...


Why won't the Samsung Authorised Dealer repair the board? It's not that difficult!
There will be a power fault and the picture is not "building" properly. At worst it will be one of the memory chips.
With a reflo soldering machine, no problem.

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.

I have a 42" lg plamsa tv the screen went black and still had sound.. found a blown fuse on the board to the right of the power board, when i replaced the fuse,it will power up and then 5 seconds later i...


The fuse you have replaced would have been on the sustain board, now that it clicks indicates a problem either with the control board or the sustain board. You would need to disconnect the connector from the power board to the Y-sustain board (left of power board) to check if the Vs & Va voltages are present, if so then the power supply will be working ok & the problem will be with the previously mention boards. There is the possibility that the plasma display screen could also be faulty.

NORCENT PT -4233


Norcent PT4233 no picture, black screen, but has sound. How to repair

The display (PDP - Plasma Display Panel) at the heart of this unit is a LG 42V7 model. There is a known bad solder "defect" on the YSUS board that causes this board to fall unexpectedly.

The bad news is that you have to replace all the primary boards on the display - ZSUS, YSUS and CTRL boards, as the failure can/often takes them all out.

The good news is that LG makes a repair kit for this panel. Its part number is 687VSNB03E and it contains the three boards LG6871QYH036D (Y SUSTAIN), LG6871QZH041B (Z SUSTAIN) and LG6871QCH053G (CTRL).

Hope this helps
