Question about Akai LCT2660 26 in. HD-Ready LCD Television

1 Answer

No Picture & No sound. Red LED, Green LED, Red LED.

MODEL #LCT26Z4AD, No Picture & No sound. Red LED on. When power on, 5 second Green LED on then 1 second off and 1 second on Green LED again then back to Red LED on. So TV does not get picture and sound. I took it apart and there does not seem to be any bulging caps on the power supply board or anything visibly burned. I scanned solder joints on the boards and they looked ok for TV sets with no visible cold or over heated ones. The voltages come up to full value when the power green light is on and when the back light tries to light with 3 fast striking/arcing sounds deep in the set the power supply will shut down. I assume back light is florescent and the striking sound is a ballast of some kind. It sounds like a possible bad solder joint on power supply or bad cap????
Any comments are appreciated.

If the power supply outputs are good! Then I would say the back light inverter is bad! If the screen stays black and does not come on.

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.)

We have a 2007 Sony Bravia 46" KDL-46VL130. There is not sound or picture. When we power it on the green light comes on blinking once and then the red light blinking once and then the green light stays on....


Does the front light stays green ? Or goes back to red ? The back-light going on/off maybe the problem, but it shoul return with a red blinking led (4 times ?) and if so it can be a power inverter problem.

Turns on, lower right shows "DIGITAL TELEVISION"


Good day!!!

That problem is usually cause of bulged capacitors on the power supply board..

This the sample picture of your power supply board and I marked the possible problems on capacitors..
2_2_2012_2_50_18_am.jpg
Things you will need.
1. A plastic flat end screw or any object with flat ends....to 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.

Hope it helps..

The TV shutdown error code can help you with this problem. If the power led flashes green for 2 Min's then red. The Lamp led should flash red 1-2-3 or 4 time every 5 Min's. These are error codes that may point you in the right direction to you problem.

Green power light comes on for a split second, then red.


The power supply (AC adapter) is bad. It has enough power to light the red LED, but not enough to power the TV.http://shop.ebay.com/?_from=R40&_trksid=m38&_nkw=12+volt+5+amp+power+supply&_sacat=See-All-Categories
