Probably a power supply failure. The blue light merely indicates
power is getting to your TV, not what is happening inside.

SOURCE: hi,i have an hitatchi p50t501

The Blue Blinking Light Hitachi.

When the light blinks 4 times it means you can possibly have 4 problems with your plasma.

1. X-Sus
2. Y-Sus
3. Power Supply
4. Sdr U or D

A good way to determine if you can fix this problem yourself is if you can build a PC. If you cant this can cost you upwards of 600$ to fix.

First get a flat area and lay a soft blanket down and lay your TV down so the back is up. Then goto your PC and goto Google and type "P50T501 Service Manual .PDF" you can buy it or if you look hard enough you can get it for free. Next in the service manual it will have a diagram of the Circuit Boards and their locations. Take the back off your Plasma and check the 4 boards. Look for burn marks, cracks, smoke mark. Take your time and look closely. When you find the broken boards unplug it and take the part number and find the replacement online. Plug it in and you should be good to go.

When i had 4 blinking lights i had to change my SDR U and D boards. They cost 100's a piece for Refurbished boards. Keep in mind im a contractor not a techno geek, and i was able to diagnose and fix my problem rather easy.

I have a rca model 40LA45RQ that will not turn on. When you hit the power button the light turns blue but no picture or sound. I tried replacing the power supply board and that did not fix it.


Fault to its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Ouku single din no sound from rca cables


Sorry I did not use the video out RCA cables. My audio RCA cables worked fine... I ran them to my JBL amplifier through a conversion adapter. I did not run it direct to the amp.. I used Metra TYTO-01 03-08 Toyota Vehicles Harness for JBL SYS (Ebay item 160560648718) and it worked great.

Here is the wiring color coding that I found online:

Rca 40LA45RQ . power light comes on but nothing else (no picture, sound, menu). Unplugging and plugging back in does not work (anymore).


Mine is doing the same thing. Drives me crazy. Usually turns on in the morning, but not at the end of the day. Makes no sense.

Trying to hook up playstation 3 with either HDMI cable or RCA cable Neither one is producing anything? WHat could be the problem?


For the HDMI your TV input for that HDMI input may be skipped you should check and make sure that it is not greyed out and that you can select it. For the RCA.... You should make sure that you are hooking it up right. You either have composite cable 1 yellow video and a red and either white or black left and right audio to Yellow video and Red and white on the TV, or you have component which will be red green and blue all three will be for video and you will need 2 more rca jacks for audio. It matters where you plug the red green and blue cables as well. getting them backwards either won't work or will give you a tinted picture.

Additionally, make sure that your TV doesn't share inputs. Some TVs will have Video 1 and it will be composite RCA and HDMI and you can select which to use. if it sais HDMI one and Video one you should be fine there if both say video one or the like they are likely shared

Hope this helps!

I am getting a blue screen. It is hooked up to a satlite and is on the same channelas the satlite box. What am I doing wrong?


If the TV is usually viewed on channel 3.
On the remote control (original RCA TV remote) manually enter the digits 0 and 3 -the tv should display 03 and work - if this dosn't work plug three wires from the back of the satellite box which say out to tv - video and audio left right. plug the othe end to video/audio input 1 on the TV (matching the colors then press the video (or source button ) on the remote. Be sure the satelite is on (green light is on)

How do i hook up a nintendo to my tv which cords go where and can someone walk me through it


Round peg into the round hole. Red peg on the red slot. etc. If the wire from the nintendo doesn't fit the slot on the tv then you're in the wrong slot. if the wire from the nintendo fits the slot on the tv (and is the same color if you are using red/white/yellow rca cables) then you're good. here's a hint on connection types (you will not mix): 1. RCA (red/white/yellow round connectors) Red=right audio sound White=left audio sound Yellow=video connect to the slots that look like they want some. 2. Coaxial (stiff cable with a pinner poking out of the end -- same cable that connects you to cable tv) just hook it up by itself; it carries audio and video. 3. Component (red/green/blue)(red/white) two 'bundles' red=red component of video green=green component of video blue=blue component of video red=right audio white=left audio 4. VGA + (red/white) VGA=video (computer monitor cable) red=right audio white=left audio 5. HDMI (flat hdmi cable. you spent $30 on this 3 foot ****) HDMI=audio and video 6. hugs and kisses hugs=video kisses=audio (both sides)

The dvd works fine but the vcr does not. the picture rolls.


The VCR is connected throug an audio/video cable (red, white and yellow) This happen because the electronic ciruitry on the combo "read" that the signal is going out to copy, and this devices have a copyraigh protection circuitry tat don't allow to do this, is not your fault, but making the connections like this, the systems automaticly activate this feature. If you can change the tv with one taht at least have the white and yellow RCA terminals, your problem will be solved definitevily.

Lg tv and parcific vidio


YES, DOES YOU PACIFIC VIDEO HAVE COMPONENT , COMPOSITE OR HDMI OUTPUTS ON THE BACK ? THE HDMI HAS BOTH AUDIO AND VIDEO SIGNALS AND IS THE BEST QUALITY PICTURE. BUY THE CABL AT RADIO SHACK, WALMART ETC.
COMPOSITE IS THE YELLOW RCA CONNECTOR FOR VIDEO AND RED AND WHITE RCA CONNECTORS FOR LEFT AND RIGHT AUDIO.COMPONENT IS THE RED, BLUE AND GREEN RCA CONECTORS AND RED AND WHITE FOR AUDIO L & R.
