Question about Panasonic Viera TX-32LX70 32 in. LCD TV

1 Answer

Red LED blinks four times

Push power button get the usual double relay clicks. Green Power On LED flashes as usual for a few seconds, screen flashes quickly then TV powers down. LED then gives red four blinks error. Service manual suggests this could be A board, P board or XY board. I have replaced P and A boards completely but still get four blinks error. I am loathe to spend more on other boards as I've heard of people replacing all boards and it still shows a problem. Is it maybe a problem with the screen or LED strips?

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 stage 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, to many popular brand TVs and other devices. Viewing it in "Mosaic" will make surf easy.

    Yes, as mentioned, I worked out from the Service Manual that four blinks on this model is a problem with A board, P board or XW board. Having replaced those, I still get the four blink error

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.

New smoke detector, new batteries, red light flashing is that normal


copied from the manual, available at the kidde website

RED AND GREEN LED INDICATORS This smoke alarm features separate red and green LED indicators. The LEDs indicate the following: GREEN LED CONSTANT ON - AC power is present. OFF - AC power is not present. RED LED - Can be seen through the Push-to-Test button. Blinks once a minute - Indicating presence of a working battery. Blinks once a second - Smoke alarm senses smoke and simultaneously sounds an audible alarm. Blinks once every 10 seconds - Smoke alarm is quieting an unwanted alarm (Model ADC only). (Interconnected system only): OFF - Another smoke alarm in the network has sensed smoke and is signalling this alarm.

Sony bravia kdl55hx729 3d led tv turns on 3 seconds shows picture than four red flashes


Hello,
the error light sequence that you are seeing is indicating a "backlight error". Most likely you have a bad inverter board -the board that powers up the back-lights behind the display panel. They might be available via ebay if you are a DIYer, or you need to call for sony service.
Good Luck!

Wont light up


the colorwheel needs replacing. if the colorwheel won't spin, the lamp won't light. if you hear a high-pitched whir, the colorwheel works, which means there is a power supply issue. there is a fix for that, but you have to be good at soldering. if you are give it a try: http://www.infocus.com/service/asc/communications/tech_notes/2006/09/tn495g.pdf
