Vizio 46 lcd. Upper 4/5 ths of picture is perfect. Lower 5th is a there, but has parts of the upper picture "ghosted" into it. The highth of this bad section approximates the highth of the scrolls of business channels like CNBC, Bloomberg, Fox News/business Channel, or the overlay highth of U-verse information overlay. I swapped U-verse STB boxes and problem stays with TV.

Precor Error 30, 31, 32 and 33, Communications Error Probable Cause 1. Bad interconnect cable between upper PCA and lower PCA.
2. Interconnect cable is mistakenly plugged into the CSAFE connector at the upper PCA.
3. Elliptical 5.17 equipped with old software version 1.01 in upper and lower PCA.
4. Upper and lower PCAs have mismatched software.
5. Another component plugged onto the PCA is overloading the +5VDC power supply.
6. Bad lower PCA.
7. Bad upper PCA.
Corrective Action

1. Test unit with a know good interconnect cable or test the interconnect cable for continuity. Replace interconnect cable if necessary.
2. Disconnect the interconnect cable from the CSAFE connector and attach to the proper position on the upper PCA.3.
3. Replace the upper and lower software of the 5.17 elliptical with the most current versions.4.
4. If one of the PCAs is found to have software version 1.01, replace it with the most current software version.
5. Disconnect all components from the upper and lower PCA leaving the data cable connecting between the upper and lower PCAs and the AC power going to the lower PCA. If the unit shows any error other than the error 3x, reconnect components one at a time. Reset power between each newly connected component until the error 3x reappears. Whichever component was last connected when the error 3x reappears, is the cause for the error. Replace the faulty component.
6. Test unit with a known good lower PCA. Replace the lower PCA if necessary.
7. Test unit with a known good upper PCA. Replace the upper PCA if necessary.

Check your owners manual for the correct shift pastern...It is a natural H pattern, with 5th gear upper right...reverse should be all the way to the right and lower right to engage...the knob does not always indicate the correct pattern...may have been changed...also be sure it is a 5 speed...most of these Cavaliers were 4 speeds...with reverse being upper right instead of 5th gear upper right...confirm in your owners manual if possible...will show illustration...Hope this helps.

Check you voltages before just swapping out boards. Although a YSUS is common for no picture, so is your upper and lower Y Buffer boards or the panel itself. Check youe -VSC voltage. Does it look like it is being loaded down? If so then your YSUS is not the problem. You can run the set with just the upper or lower Y Buffer boards untill the load is gone. That will let you know wich board to replace.

It can be main board, T-CON, or LCD panel. I would try reseating the ribbon cables between the T-CON and the LCD panel first.Unless you have service manual and scope to look at the signals it will be difficult to be 100% for sure as to which board is bad, the repair guy will more likely to do board swapping, starting with the T-CON board.

Issue with your White balance Chipset Check for Diode and Capacitor leakage

If original problem was caused by sediment burning out lower element, did you clean sediment out of water heater when changing lower element?
Two element water heaters are 240V.
Thermostats cut power on one hot wire, but 240V circuit has 2 hot wires. So lower element has power at all times coming from the red wire.
1) Use ordinary tester or multimeter set to 240V <> test each screw of lower element to bare metal part of water heater. Each screw should show 120V. If there is no power, then upper thermostat is defective, screw on upper thermostat is loose, or red wire between upper and lower parts of water heater is bad.
2) Remove wires from lower element. Use continuity tester or multimeter set to ohms <> test across both screws of element to see if power travels through element <> if element is bad, then continuity tester will not light up and multimeter will show no ohms. Put wires back on element after test.
3) Start with cold water in tank. Turn on water heater & upper element will turn on. Put ear on side of tank to hear if upper element is heating water. Test #3 screw to #2 screw on low left side of thermostat, should read 240V > Test #3 screw to #4 screw on low right side of thermostat, should read 0V.
Put ear on side of tank. When upper element turns off: Test #3 screw to #2 screw on low left side of thermostat, should read 0V > Test #3 screw to #4 screw on low right side of thermostat, should read 240V. If this test shows 0V and 0V, then upper thermostat is bad. If reading is correct, immediately move to next test.

4) Turn temp on lower thermostat to 150. Using ordinary tester or multimeter set to 240V <> Test across both screws of lower element. If there is no reading, and you know element is good from step 2, then lower thermostat is bad, or wire is bad between lower element and lower thermostat, or wire is bad between lower thermostat and top part of heater.
5) Test across both lower thermostat screws, should read 240V.If this test is good, it means wires are good. Put jumper wire across both screws of lower thermostat, and test lower element again. If element finally turns on with jumper wire, then lower thermostat is bad.

If wire is bad between upper and lower parts of water heater, and water heater has tight-fitting 2" foam insulation, it usually indicates water heater replacement.

Use the upper holes. Should be either a 100 x 100 mm (4" x 4") or 200 x 200 mm (8" x 8") or 100 x 200 (4" x 8") on this size television. Most mounts show the mm spacing, so purchase a mount that works with your spacing.

looks like a bad Y main I would try replaceing the upper and lower y boards first.

This can be a failure in the panel itself, or the driver circuits to the panel. It is serviced by factory level diagnostics and board replacements. This take specialized training, tools, and setups to perform.

Considering the set is 5+ years old, it most likely will not be cost effective to service. There is also the possiblilty that the circuit boards may no longer be available. I would suggest to replace the set rather than service it.

When servicing a set with a number of years of use, there are many other components and circuit boards that can potentialy fail. As electronic components age and have use, the posibility of failure increases.
