Re; TCL PLASMA (PDP42U3H), I switched it off through remote control one night and for the next 8-10 days there was no power coming to the unit, then all of a sudden it was all good again working normally. Then a few weeks later same problem, and the power hasn't come back now for the last month. I was wondering if can help me with this problem?

If the set is only 9 months old, you should call for warranty service right away as this coiuld be a costly problem. This problem sounds like the main board is bad and you will be looking to pay about 500 to 600 bucks if you do not get it repaired under the warranty. Good Luck

SOURCE: Convergence Problems

If you did not use heat sink compound then you probably have not hurt the new IC's yet but you should remove them and add the heat sink compound NOW. If the convergence IC's are bad then you will have access to the convergence menu but the adjustments will have no effect. The fact that you switched the IC's and got the same results shows that the IC's are good. If your red convergence is still way out when the new IC's are installed then the old IC probably burned out the low value resistor associated with the Red Vertical (RV) channel.

It sounds as if your convergence ICs have failed again,However if you didnt replace the convergence resistors with the ICs that is most likely the cause of early IC failure. There is a quick test to determine if the ICs have failed. Remove the front speaker panel and access panel up front, and you will see the convergence panel with the two black heatsinks. Directly in front of those heatsinks are three wire clips that are for the convergence yokes, Unplug those three wire plugs and try turning on your set. If it comes on the ICs have failed, and the ICs and resistors should be replaced as a kit. You can get the repair kit for the JVC rear projections at the following link with free instructions. Heres the link.

When the TCL light is on usually means there's a problem with the traction control, need to have inspected real soon. Could be a speed sensor.

I have a hitachi 50 "plasma that was given to me


First do you see a light indicating that the TV has power? There are two power buttons on the TV (the main power and the regular power button). The red standby light will light up when the main power switch is on. This indicator is just to the left of the remote I/R sensor. You can find the main switch on the bottom front of the tv (it is under the tv forward of the stand). Turn on the Main power if it is not on. Then try the power button on the control panel of the TV again.

Does the standby light change color or blink? (Red is standby, orange is power savings (no signal), blue is on.) If the main switch is on and the standby light doesn't come on, the TV has a problem at the power supply. Try unplugging the unit for a bit (at least 30 seconds) and then plugging it back in. This will reset the internal circuitry. If you see a blinking light, then the TV is reporting a self-test failure. I do not know the codes for this model Hitachi Plasma TV.

The manual for the Hitachi P50H401 TV is available from Retrevo: http://www.retrevo.com/support/Hitachi-P50H401-TVs-manual/id/1233ci869/t/2/ . You will need to enter a code to access the pdf.

I'm assuming you don't have one of the special versions that were intended for large audiences that were only controlled by remote (no control keys on the front of the TV). Remotes.com has the original remote or a substitute remote if you need it. See http://www.remotes.com/remotes/servlet/rs?a=gmi&uuid=13104063628240&smodel=P50H401&brand_pn=HITACHI_P50H401 .

I hope this helps.

HI There, I have a TCL PDP42U3H, voltages on power board are within specs. Getting full picture but very dim with lots of background noise, colours seem to be like inverted like looking at a negative with...


I was a little confused as the model is a Plasma Screened set and you wrote LCD. Not to worry. In the old days, people were told that the display on plasma screens needed to be "re-gassed", this is nonsense. The gas goes no where and is inert anyway, made up of elements like neon, argon and a few other choice U/V emmiting products.
I would say you have a power supply problem in conjuntion with a video pedastal problem. The plasma screen has a half life of some 17000 hours, which is enough for ones eyes to turn square. Thereafter the same again until the picture dulls dow to a still acceptable level.
The supply voltage is not the critical one it is the bias voltage on the video processing that is all important. Do you remember the old colour TV's with pedastel problems and negative/inverted colours, (ITT CVC9 comes to mind instantly here).
If you have a service manual, check the waveforms around the video processor for inconsistencies, if you haven't it is a workshop repair anyway but without a manual you have no real way of knowing what you are looking for.
Hope that sheds some light on your problem.

I turned the tv off the other night with the remote just like i always do got up next morning to turn it on it won't come on I have tried everything unplugging it pushing the power button on the tv instead...


Good day sir/maam, chances are you tv's switching power supply circuit has gone bad, you may try the following.
  1. open the back cover and locate the fuse, check if the thin wire is intact, (unplug the unit before opening the back cover) replace and test if the fuse blew up. test again.
  2. if the fuse is intact. replace the cover.
At this point. you have no choice but to call your dealer or repair man for service.

Our Proxima DP5800 will not turn on with remote


First check the main switch located at the rear of the unit next to the power socket.Make sure it's turned on. Next, if the projector turns on with the power button on top of the unit, then the problem is with the remote. Replace batteries to make sure fresh ALKALINE batteries are installed correctly--the batteries must SAY alkaline on them. Ordinary carbon batteries WILL NOT WORK! Check inside the battery compartment for corrosion from a leaked battery. To actually test to see if a remote is working, you will need use of a camcorder with "night shot" or night vision capability. Turn on the camcorder and set it for night vision. From a distance of at least 8-10 feet, aim the remote at the camcorder and press a button...you will see the front of the remote light up as if it were a flashlight! That is the infrared coded light the remote produces to signal the projector.If you don't see any light, the remote is bad and will have to be replaced. If you see light, the receiver on the projector is not functioning correctly and will have to be repaired.
