SOURCE: Blue light

Okay, I found a fix! Called JVC, spoke to somebody there, here it is:
1)unplug the TV completely, no wall no power strips, completely
2)wait 10 sec
3)plug TV back in and Turn it on, the light will still be doing the same thing
4)wait 30 sec
5)ON THE TV, not the remote, locate the menu, volume (-) and power button.
6)while simultaneously holding down the menu and volume (-) button, pressed the power button ONCE and continue to hold the other 2 for 10 sec.
7)on the remote control, go to menu>settings>system info
*** now this I know as a FACT will work on systems that display: JVC - ver.5.32FO001, but I don't know of any other versions***
8)press the mute button on the remote twice
9)unplugg TV again and wait 10 sec.
10) plug TV in and turn on

It SHOULD be working normally now... Thanx to the guys a JVC support for this one, I know it seems like an obvious first place to look, but sometimes it isn't. I for one checked online forums first.

SOURCE: Problem with Hitachi P50H401 Plasma TV - Will not

I have the same model, P50H401 and it developed the same problem two days ago. This set is 2 1/2 years old in service, being purchased in December 2007. The original manufacture date was October 2007.

The set was turned on and operating at the time and then promptly shut down by itself. The front blue LED power indicator began flashing four times in a loop or cycle.

The flashing LED sequence in this instance points to a problem with one of the following boards: PSU, X-Sus, Y-Sus or SDRs (there are two SDR boards, SDR-U and SDR-D, both are connected off of the Y-Sus board on the left hand side of the frame when rear facing). The set shuts down to prevent further damage to other boards or components.

I could power cycle the set but it would shut down after after a few seconds. Power LED would stay solid, I could hear the PS relays switching, and audio would output through the speakers. Then as the screen was just about to illuminate, the entire set would just shutdown. The blue LED would again go into the 4X flashing sequence.

I could not visually detect any signs of severe component damage on the main PS board. The two large electrolytic capacitors which have been mentioned as problematic in other threads seems fine. The where slightly raised on the top surface, but not blistered or completely blown open.

The only indication of component damage that I could detect visually was on one of the small surface mounted ICs on the SDR-U board.

Through reading other posts on this site, I learned that I was able to remove the suspect SDR-U board and then re-power the set. Doing this proved that the PS, X and Y Sus, and the SDR-D boards where o.k. The PS held, and the lower half of the screen illuminated. (I would only do this for as brief a period as required to determine if the the other boards would function and the screen would illuminate. Do not pro-long operation in this state so as to not cause further damage.)

It was somewhat difficult to locate the correct SDR-U board. My local service rep did not have one in stock, and the Canadian parts distributor was also out of stock. They estimated 10 - 14 business days to order one up from the U.S.A. (Hitachi closed their consumer electronics division in Canada back in 2009.)

By chance, I checked with another service rep in an adjacent town. He had a board for the P55. We did a visual comparison on the two boards and determined that it would be compatable.

The easy part was removing the defective SDR-U board and installing the replacement. The hard part was re-alinging the three ribbon tabs into the respective connectors on the SDR board. Be careful with these ribbons. The other end of each is fused to the plasma panel screen, so if you damage them, your screen is rendered useless.

I initially had the same problems as others have posted with having black or gray lines on the screen when the SDR-U was replaced. After gently adjusting the position of the ribbons as they are seated in the connectors, the lines disappeared. This was a slow and frustrating procedure, but it worked, Be patient.

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.

My JVC model. my JVC TV LT 42 EM 59 will not come on .I get no blinking blue light no power no nothing I get nothing I've tried to reset it in nothing


With no power it will not reset---if total dead unit you would have to first follow the power cord into the set to the line fuse it goes almost directly to---check the fuse first and examine the power supply board for damage or puffed up filter caps.

your lamp is burned out-easy and fairly cheap fix. Order a new lamp and install it according to the instuctions sent with the lamp.Dont believe that you need to take it to a service to have it fixed, this should be less than $150 fix-good luck
