Please remove all HDMI cables from the TV and test a different power outlet. If the problem persists then we recommend you use the below link to locate an authorized service center.

Power connector pinout for CT-13R50 television


Directly from the user manual, Page 5 under "AC/DC Power Sources":
DC Models ONLY
"This TV model operates on both standard household current (120 volt, 60 Hz AC) and car battery (12 volt negative ground DC) through the cigarette lighter. An AC power cord and a car cigarette lighter adapter cord are supplied.
Household Installation
Insert the AC power cord into the connection on the rear of the TV. Connect the two pronged plug into an AC outlet (120 volt, 60Hz). If you are unable to insert the plug fully into the wall outlet, try reversing it. If the plug does not fit, contact an electrician. Do not force the plug or defeat the safety purpose of the polarized plug."

The manual goes on to describe the vehicle installation which is identical to the household, with the only difference being the car plug goes into the DC side of the power connections at the back.

There are several kinds of power cord available for older TV models. Unfortunately, after an exhaustive search, I was not able to locate a photo of the back of that model television.
However, I have included three of the typical US power connectors found on a great many devices and in the majority of cases, one of these cords will likely be the one you need. They can be found at most local stores such as Wal-Mart, or can be ordered online from Amazon. Also, the cored generally only fit in one direction, especially if the cord happens to be polarized (thin blade and wide blade).

I hope this helps!

My Panasonic TC-21Z88RBN doesn’t displays the total picture vertically ,when the picture is display it like not in the center of the screen sum of it is disappear in the bottom


Hello

Your TVs vertical output section has the fault. You just open your TV after disconnecting it from the AC mains wall socket, and locate the vertical output section. This section uses an Ic marked as part [IC 401] on the board and its number is LA7840. Just look for any loose soderings around its components legs, and the solderings at the IC legs, which has 7 of them. The IC stated above will be screwed onto a heatsink to radiate heat out of it when it works.
If all soldering point are fine, come towards the IC legs and measure the voltages at each leg. The voltages must be
pin 1= Ground
pin 2= 12.6
pin 3= 24.7
pin 4= 4.4
pin 5= 4.4
pin 6= 24v [vcc]
pin 7= 1.8
All voltages stated above are DC voltages with respect to ground. If any of this voltage is missing, find out the reason for that. If all of them are noted abnormal, IC may be defective, and replace it.
[vcc] stands for main input voltage to the IC.
If you need any more assistance, feel free to contact me through Fixya. Ok.

When I turn my tv on my speakers work for apprx 5 minutes than start crackling very loudly then go out.What could cause this ?


Hi, My samsung dlp 46 tv was making a loud crackling and popping sound from the speakers, I turned OFF all the volume
control on my tv from the menu the srs, the auto tune volume, the internal volume which, is the main one which silences the crackling sound immediately! But, you must have surround sound and play the tv volume through your surround sound and wa laaaa, it WORKS! The tv may eventually stilll go out before or if I decide to have it fixed. It is about 3 years old.

When we will give the power to TV, fuse & R502 location resistor burn.


damage can be ascertained from the power regulator, you can check the transistor / STR power regulator, and Diode Bridge (AC-DC), check the Positive and Negative on Elco 220/450 volt power regulator, is there a short circuit? if no, probably from before entering the diode, it can be from thermistor. Hopefully help

We had thunder storms my tv 65613 has a green blinking light wont star


Good Day,mikeybecerra; TV wont come on mb try these 6 items, please pay attention to the blinking light (it's a code) : 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 # 934C067001 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). LED stops blinking after 70 seconds of plug in but will not power on. 5. LED stops blinking after 70 seconds of plug in but will not power on. Check for 3.2 volts DC at connector RF pin 4 and 5 on the Signal PCB if low suspect problems with the switches/buttons on the Control PCB part # 935D736001 6. LED stops blinking after 70 seconds of plug in but will not power on. Keyboard is not locked and key inputs at connector RF pin 4 and 5 check good suspect the E2P PCB part # 934C061001. Good Luck, big IRISH.

Joepa,
Not likely to be the ballast... Let's throw this in for help, from the Mits ASC site:
Shuts Down With Red Lamp LED
1. Unit powers on and works properly for a while then shuts off with a red lamp LED (lamp error). Suspect bad lamp part # 915P020010 2. Lamp enable line at J14 pin 6 does not switch to 5 volts after turn on, 12 and 5 volt supplies are good. Suspect the Light Engine part # 939P977020 3. At power on the lamp turns on and off three times and then the unit shuts down with a red lamp LED (lamp error). Replace the Light Engine part # 939P977020 4. Check for 12-volts DC at J-9 connector pin 4 on the Engine Driver PCB, if missing check for an open F9A09 on the Power PCB, if it is open replace F9A09 part # 283P127060 and the Light Engine part # 939P977020 5. Lamp enable line at connector J14 pin 6 on the Engine Driver PCB switches to 5 volts after turn on but does not go back to 0-volts (low) after 5 seconds, 12 and 5 volt supplies are good. Suspect the Light Engine part # 939P977020 6. Check for 5-volts DC at J-9 connector pin 1 and 2 on the Engine Driver PCB if low or missing check C9A37 and C9A38 both 3300 UFD 10 V part # 181P732040 on the Power PCB part # 934C148001 From the noise you described it could also be that the color wheel is failing. Fans and the color wheel can cause shutdown. And if any of this sounds too complicated it's time to bite the bullet and take it into the shop. Find a reputable shop and one that will give you a written estimate before proceeding. If you ned help locating one try the NESDA locator: http://www.nesda.com/locator/state_search.php Hope this helps. Bill
