Circuit board blinks 4 times

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.

Blinking codes details to many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty.

The error codes, blinking red twice, should be described on the electrical diagram which is probably on the back of the panel you had to remove to see the circuit board. If not there, check the manual, which you can probably download.

Just check whether any electrolytic capacitors you have changed recently have placed in reverse polarity. Electrolytic capacitors will have both (+ve) and ( -ve ) polarity, marked on them. The circuit board too will have these markings, and the legs of the capacitors must coincide with these markings. If any one among them has been placed in reverse direction, the voltage rail to which this capacitor has connected will go very low, and a short circuit indication blinking will occur. Check this first.

4 blinks Power SOS P Board
Try opening it first look for some bad connections or so if they are none use a hair drier and heat the board looking for the place that creates the 4 blinking then use the hair drier on cool to cool the place and get this time little longer.

found this tonight:
1 blink STV 5v sense DG Board
2 blinks 15v SOS D Board
3 blinks 3.3v SOS D Board
4 blinks Power SOS P Board
5 blinks 5v SOS D Board
6 blinks Driver SOS 1 SU / SD / SC Boards
(SC energy recovery circuit)
7 blinks Driver SOS 2 SU / SD / SS Boards
(SC floating voltage area)
8 blinks Driver SOS 3 SS Board
(SS energy recovery circuit)
9 blinks Panel Config. SOS
10 blinks Sub 5v SOS / Main 3v SOS DG Board
DTV 9v SOS / Tuner Power SOS
11 blinks Fan SOS PB Board
12 blinks Sound SOS H Board
13 blinks Communication error DG Board
with IC8001 (Pesks Lite 2)

4 times standby light blink shows that tv got problem in vertical deflection section and probably vertical output IC got defective, need to be replaced.
Replacement of parts in circuit board requires soldering work and expertise so call local tv repair shop guy if you are not familiar with soldering work.
Thanks.

thought I would post this here for everyone.

trying to get the compressor to operate. it could be a bad capacitor and the compressore wont start or maybe the compressor is burned up
