Mitsubishi 52525, The picture in non-HD channels is not centered on the screen. Likewise, the display output from a home theater pc is not centered from the VGA output. Can you tell me how to adjust these images on the screen? I saw a repair man make center adjustments before but I don't know how he did it.

Fault at its main digital 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.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Hitachi 60vf820 displays red flashing light above power green light and picture will not come on.


There are 2 or three things wrong with this T.V. Step one:
Make sure the Bulb is good by taking it out of your T.V. and inspecting it.
If it is bad...

This lamp already has the housing with it, just swap it out.
Two, you could have a bad power supply- Repair is usually 240-280 bucks in shop.
3: You could have a bad fan. The fan on this T.V. that goes bad is a nightmare to get to and I highly recommend a service man to do it.

Hitachi 51UWX20B no sound, no picture, blinking green LED


The 392-150 is a higher current device then the 110---you can use either--this is normal in the hitachi sets---I usually replace both with 150's---check the led that does not light---should indicate which voltage source is bad---if it is one of the 2 voltages for the convergence ic's(one is a positive and the other a negative voltage) then the convergence Ic's may be bad---look for any discolored resistors around the ic's---one way to tell if it is a convergence ic is to de-solder both ic's and see if the set turns on(the convergence will be out the window) but if it comes on change both and do the alignments with the Hitachi remote. By the way----the led should have a location number printed on the top of the circuit board.

Hitachi 55FX20B 55 in. Rear Projection - no picture or sound


TV always has high voltage shock risk while repair. As you said you are not familiar with TV repair so better to handle repair person this issue.

No picture or sound


Remove the rear panel. With the TV on you should see a red LED near the center of the PCB. There should also be 5 green leds, 3 to the left a 2 behind. If there is no red leds, check the fuses. If there are no green leds or maybe 1 or 2, disconect PSD5. It's a connector on the left side of the power board that connects to the audio board. It's the 3rd on fro the back. It's labled. With that disconected, turn on the set and look for the green leds. If all 5 light, the power supply is OK and you have a problem beyond that. If they don't all light you have a bad power supply.

Pt-50lc14 50in.


I went ahead opened the back cover and surprisingly noticed it's pretty dirty inside after 2.5 years of usage, and there is a thermal fuse to protect the ballast power supply. Spend 99 cents replaced the thermal fuse and the TV came back alive. I am surprised that it's such simple to fix the problem vs many others frustration.

LCD TV is more fragile than the traditional TV as it uses expensive HID lamp. So the cooling system inside is very critical to prolong the lifetime of the lamp and the special power supply. Dirt collect inside is probably the major cause to degrade the cooling system. Make sure you clean them (two fans and a lens) whenever you have a chance.
