Question about Hitachi 32UDX10S 32" TV

Hitachi Ultravision Digital TV dark picture

I have a Hitachi Ultravision digital tv that has a very dark screen. Sometimes the picture will get bright and is ok for viewing but then it becomes dark again and I can barely see anything. What is wrong? This tv isn't very old and I don't feel it should be having this problem.

Thank you!

Looks like

1. A Cold solder in the Video Output stage power supply.

2. A bad Electrolytic Capacitor in the above Video Output stage.

I generally do not waste time in attempting to locate faulty capacitors. There will be only 6-8 pf them in the above stage / section,m and the klot of them would collectivelyt not cost more than 3-4 $ equivalent, in india. Just blindly replace the lot, and the set is ready in 30 mins.

Dunno how much they will cost in your country. Try to look for a 100mfd, 160V Capacitor. Close your eyes and replace. generally does the trick.

Check the voltages that comes to the back light inverter, especially, the voltage from the main digital board that controls the brightness. If is found OK, be sure that the backlight inverter board is faulty. If not, the main baord. If you wish to get some details, check the site linked here. Pull up older posts.

Picture is very dark on all channels. Settings have not changed. Do I need to replace the bulb?

You may need a drive PCB. This PCB can cause the picture to be too bright, no brightness or picture too dark, intermittantly or permanantly. Do check the bulb though and see if it is foggy looking or dull especially if it has not been changed. Thanks for using Fixya.

Blue shadows appear to be behind white objects

TV shows large red spot in middle of tv when dark show are on, you can see it more.  Now blue spots on upper right side too.  Spend way to much on this tv to have these kinds of problems only after 3 yrs.

Many thin black horizontal lines on my Hitachi Ultravision 50" TV

Good Day, LDS also;
You may have a poor seated cable connector. Unplug TV from A/C, remove back look for a large black connector. It connects between the Main Digital Module and the Drive PWB. Re-insert both ends several times to make better contact, use contact cleaner if have but not always needed. Good Luck, big IRISH.

No picture or just one line across screen on hitachi ultravision rearproj.

Could be a loose connection on the printed circuit board in the Vertical deflection circuit.
You would have to have a qualified technician to repair this problem.
A intermittent connection in the circuit described can cause a horizonal line across the screen.
You have to be careful and not leave the TV on for a period of time with a bright line, as it can actually burn a line on the CRT screens, which is permanent.
