Re: Television goes off without turning off

Your set needs to be repair by a tech you are having a problem in your power suply which is intermittent.either your hrizontal ic is shorting out, or your regulator or your microchip ic.or the diode that couple the collector of the horizontal transistor with the b+ from the fly back.or check for lose solder in the horizontal output or power supply. good luck

Tv wont turn

The blinking red light at the the front of the television is the "Diagnostic STANDBY/TIMER LED".
This little red light will blink 2, 4, or 5 times and then stay off for three-seconds. And blink again for 2, 4, or 5 times. This cycle repeats. The most common diagnostic code is the 4-blink code.

When the red LED blinks 4-times, it means one of two possible causes:
1) +13V is not supplied on the A-board. Or, 2) IC502 is faulty.

It is best to take this television set to a repair facility and ask that the +13V power supply be repaired.
The copper tracks and integrated circuit pads are very thin and delicate on the KV-24FV12 circuit board, and will easily lift off of the circuit board, if the incorrect desoldering tool is used. Unless one has a good quality PACE vacuum desoldering unit, one should not attempt to repair the television.

TV turns off by itself after being on for 60 seconds

Led blinking Three times means B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672.
Hope this helps.

Dead, led flashing red/green at first, then going to red standby
Replace C604 (1000uF, 16v) elec. cap. It is in the decoupling circuit for the 5 volt supply
Red led blinks on / off, TV does not turn via power button and/or remote but after 20 minutes or so it turns on and works fine
Replace R902, R901, R905, R903, R900A, Q902, and possibly the two (one small and one large) capacitors in the section labeled as the power supply. The board will be black under the components that are bad. Q902 is an NPN transistor and is hard to find.
