Tv gone dim
You can try this, from the rear with the back removed locate (hard to miss) the three large round black lens, they are on top of the three picture tubes the set uses and are your light source, if you can reach them clean them with a lens cloth or a paper towel with glass cleaner sprayed on the towel.
over time they get dusty and the picture will get dull and dimmer.

My Hitachi 57F59 was scrolling thru the channels without anyone touching the remote - I unplugged it for two days and now it keeps flashing the
Keyboard issues and answers:A problem that is more common than most people think is an issue with buttons on thecontrol keyboards of modern TV sets.
Recently for whatever reason I have seen more questions about this so I have composed this answer and solution for these kinds of problems.
It can be any button on the set-channel up/down or volume up down-you name it.
The symptoms are the same: channel will scan up or down andwill not stop-remote control has no effect on this---It can be channel, volume,or even input or menu if the set has those up front or on the side of the set.
All these push controls have something in common-beneatheach is a tiny momentary push switch-when pushed with the plastic button itperforms a specific task (vol up or down etc.)
What happens is the afflicted switch beneath the plasticbutton is bad-when released it is supposed to stop its function but does not.
Keyboard or button controlled features have PRIORITYover the remote control, hence the remote will not stop this fromhappening.
Both the remote and thekeyboard go to the microprocessor in the set but keyboard is first in line.
How to resolve this issue?
Someone needs to get at the tiny pc board with the buttonsand locate the one associated with the issue (ie sound or channel etc) andunsolder that switch from the board-usually just two pins (may be more formounting only purposes) and then see if set does not have the issue with switchout of the circuit.
For the TECH minded with the board out test here theswitches with a ohm meter set to high resistance-any reading with button notpressed means a bad switch-seen ones that read 5,000 plus ohms-it may benecessary to unsolder more than one switch to locate the offender here but an open reading with switch not pressed is therule.
I have taken the time to compose this answer as some do notunderstand what is happening in these types of situations---No magic wand orsmoke and mirrors here-have to disable the offending switch to know.
The beauty (in my view) of this kind of problem is if found, you really do not have to replace anypart-just operate the set with the remote with one button that no longerfunctions on the set itself-who could ask for more?

TV screen Repair
Good luck trying to find one used. This model was first produced and sold in 2006 and is one of the last projection sets Hitachi made.
Part number for the screen unit is: UX26082 and retails for 251.38 not counting shipping etc.
Replacement requires removing the entire front screen with the plastic frame it is mounted into.
It consists of three separate parts--outer or clear protective screen and the two inner ones and all three are only sold as a complete unit.
You have the part number and if you Google it may find some vendors on the internet who have it.
Let me know if I can be of help.

My Hitachi 57F59A RPTV screen just went blank and
If your power light is coming on and the television is not turning on, then there is a problem inside the unit and it mainly is on the main panel or the power panel.
The problem simply is a bad capacitor, either on the main panel or the power. It probably got burnt or swollen therefore not allowing power get to the the screen.
First open up the television, then assess the main panel and the power panel for any bad capacitors, once any is detected, all you havge to do is to replace it with a new one, by turning the panel to the part that you have the tips of the capacitors, then you melt off the lead from the old capacitor using a soldering iron, then replace it with a new one and solder it on the panel with some lead.
After doing that your television will be in good condition once again.
Take note to unplug the television before doing this, or you can seek technical assistance from a professional if you are not familiar with such activities.
Take care and good luck

Tv wont come on.
Thanks for using FixYa. From what you have described it seems the issue is with the some components that have gone bad on the power supply board however, it can only be checked once you open the back of the set and blow all the dust off then start by checking the power supply unit for swollen/bulged capacitors and burnt wires/components on the power supply board of your TV. Please do accept the solution if the issue is resolved or else revert for further assistance.

No picture from Blu-ray
If the TV works fine with other sources the problem is the HDMI output is not enabled on the BD player.
Most BD players do not output both HDMI and composite formats simultaneously. Check to make sure the HDMI output is selected on the BD player and the TV. This information is in the manuals, read the book.
