You will need to tell them the model number of your set & what the plug looks like that goes in to the TV set whether its standard DC plug or has 4 pins.
Tell them Chris at Televid told you to call they will look after you.

Mitsubishi tv pop, now no picture and it has a grey spot on the screen.

If you are a tech type
Disconnect Power
Your Modern Digital TV is just a Computer with CPU & Video Memory.
No 25KV voltages to worry about.
There is a shock hazard on AC side of Switchmode.
Electro Caps on AC side can hold 110 / 240v

Check Switchmode internal power supply on DC Side for bad capacitors.

Toshiba 50h60 tv has power but no picture

Although most HD TVs are 120 VAC devices, they actually have step-down power transmission sectios that take the line voltage from the wall outlet and turns it into the 13.8 VDC needed to run the HD TV. So, what does this have to do with the price of tea anywhere? The answer is that if you look at the output side of the power supply circuit, you will see the 13.8 VDC power signal appearing. That voltage, though, is there to tell you that power is available.

Now, take a look at the power supply circuit either in the owner's manual (if it is supplied) or on the lid of the power supply in the HD TV itself (warning, only open this device if you are familiar with and comfortable with working with voltages and a DC volt meter) and you will see at low-amperage circuit -- in the 1 to 5 amp range -- and a high-amperage circuit -- up to 20 amps. This is the important circuit because it drives the TV.

You will have to go into this device while it is on, so extra careful that you stay away from the AC input. You can look at the DC output because it is low-voltage.

Placing the probes of a volt-meter (in the appropriate range setting) across with the black (-) lead to ground and the red lead on the high-amp positive lead, measure the voltage. You should read 13.8 VDC or a similar reading. If you do not see any voltage on this terminal -- which I suspect the the case -- then you will have to replace the power supply. If you feel comfortable handling this repair, you can do it yourself. I would suggest taking it back to the store where you bought it and have them fix it -- to keep the warranty intacty -- or have them send it back to the manufacturer.

My 73'' mitsubishi model #wd-73738. Is flickering.

That's a clear indication that you have a bad power supply in your TV.
If you know how to DiY...I suggest you open your TV. Locate the power supply section, it is where the end of the power plug is connected. Replace all blown or bulge or leaked capacitors with same value. That will fix your TV problem.
The hardest part is to disassembling your TV cover, cause you will need to pry off the snap in lock at the edge of your TV.

Power supply board should look like this. Examine the capacitors in the board

After replacing blown should work again.

Things you will need.
1. A plastic flat end screw or any object with flat fry off the cover
2. Soldering iron.
3. Soldering lead
4. Soldering pump.
5. Flat and Philip Screw
6. Replacement capacitors (of same value with the blown one) that you can buy to any electronics store.

Or try replace light engine..if the above solution won't work..

Cooling fans not working

Check for the 12v dc going to the fans from the power supply. If voltage is present , bad fan, replace fan. Encompas Parts.

My TV won't turn on. The Green light just keeps on flashing

1. Check for no 8.4 volts DC at pin 3 of PC9A10 on the Power PCB, if low or missing replace PC9A10 part # 268P058020. 2. LED does not blink at plug in. Check for 3.3-volts DC at connector RF pin 3 (system reset) if low or missing suspect the reset switch S7L20 part # 432P109010 on the Control PCB. 3. LED does not stop blinking after plug in. Verify the standby supplies, 12-volts at connector KA pin 17, 6-volts at KA pin 18 and the 28-volts at KA pin 19, if the supplies are present suspect the DM PCB part # 934C067002 4. LED does not stop blinking after plug in. Check C9B01, C9B02, C9B10, and C9B11 (1000 UFD 16) on the DM PCB, if they are bad replace them with part # 181P734030 (680 UFD 16 V). 5. LED stops blinking after 70 seconds of plug in but will not power on. This model is equipped with a keyboard lock feature; this can be mistaken as a no power condition. To unlock the keyboard press and hold the "menu" button on the front panel for 10 seconds 6. LED stops blinking after 70 seconds of plug in but will not power on.
