Brand name and model number?
These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

it is a bad fan. it also could be a power supply. Quite often the real problem is dirt clogging up the fan(s) to the point that they need to be replaced. Operation of the set in a dirty environment is not a good idea

That is the blink code for the lamp ballast. Here is the more complicated explanation from the service manual.
IC2301(pin11) detects the error of LCD Power C.B.A. and Lamp,
then indicates the error when an inner malfunction of LCD Power
C.B.A. occurs, the Lamp voltage becomes more than 130V or
less than 30V, Lamp current becomes more than 5A, or the Lamp is blown
Hope this helps.

5 blinks means AKB detected. Try turning down all 3 screen adjustments slightly.

You need to replace the capacitors on the power board. this is a very common problem with the RCA dlps See my tip under my profile for the ATC336 chassis RCA, your model is the ATC311 but it applies to your model as well.

I have over 10 years experience in electronic tech support.
I
know this isn't what you want to hear, but the problem you've described
can't be fixed with troubleshooting. Your TV will have to be repaired.
There is a part that has developed a defect and needs to be replaced.
The 4 red blinks is similar to an error code. It represents what's wrong with the TV to a service tech who knows how to repair it. If you're still in warranty, the TV will be repaired at no charge to you. The warranty would likely be at least one year from the date of purchase from the manufacturer. If you purchased an extended service plan they will repair the TV at no charge as well.
If the TV is no longer in warranty, it will likely cost a minimum of $150 parts and labor. This is assuming that you only need a power supply module. If the problem is one of the video circuit boards, the price of repair could go much higher.
I hope I've provided you useful assistance and that this information
allows you to make an informed decision as to how to proceed from here.
Please be sure to vote on my response. I hope I've earned a good rating from you today.
Please let me know if I can be of further assistance.
LED Indications
The front panel Status LED provides an indication of
the set's operation and the possible cause of a malfunction.
If an abnormal condition is indicated, perform the
Self Diagnostics procedure.
Self Diagnostics
To activate, press the front panel <ACTIVITY> &<CH
??> buttons at the same time and hold for 5 seconds.
The STATUS LED will then flash denoting a two digit
code.
• The number of flashes indicates the value of the
MSD (tens digit) of the Error Code.
• The flashing then pauses for approximately 1/2
second.
• The LED then flashes indicating the value of the
(ones digit) of the Error Code.
• The Error Code is repeated a total of 5 times.
Example: If the Error Code is "23", the LED
will flash two times, pause, and then flash three
times.
Table 2-2: LED Indications
Error Codes, descriiptions and the most likely cause of
the error are listed in Table 2-3.
Note: The TV must be in "Shut Down." The LED
will probably be indicating an abnormal
condition. If the TV is switched Off, AC is
removed, or a System Reset is performed, the
code automatically resets to "12" No Error.
See the Error Code Log to retrieve a history of
errors.
Note: Use the front panel buttons, not the remote
control.
Note: If there is no response, the front panel may be
locked by a V-Chip setting. To unlock, press
and hold <ACTIVITY> on the front panel for
8 seconds.
LED Indication Condition
Off Off (standby)
Green Power On
Slow Blink Green Power Off with Timer Set
Fast Blink Green (80 seconds) > Off Power Off (Cooling fan still working, 80 sec)
LED Indication Condition
Red Lamp Failure
Yellow TV Too Hot
Slow Blink Red TV May Require Service
Slow Blink Yellow Lamp Door Open or No Lamp Installed
NORMAL INDICATIONS
ABNORMAL INDICATIONS (For details perform Self Diagnostics Procedure.)
