I have a Haier 75uf2500a tv set. It appears the backlights are not working. What kind of backlights are needed? Do you have schematics? Do you have the steps to fix it? Thanks

Be sure you have power ( voltage) from the power supply to inverter boards. If not suspect power PCB part# 8142132110050 available from Encompass for @ $115.00. if that voltage is present suspect invert PCBs which are part of the panel & is No Longer Available part# 8137751900202.

if inverters are bad you might try to research possible availability by researching individual part # from the boards themselves to see if you can find any availability. possibly from partsandproducts.net. They list about 5369 various numbers

SOURCE: need code for "20" Haier tv model tn201auv for rca guide plus+gem

Hi again,

It would seem that you posted multiple times.

For the manual of an RCA CRK76TA1 remote control, pls click here. It is a pdf file and would require Adobe Acrobat reader.

Offhandamnot sure if an RCA remote would work with a Haier television. Youcouldof course still try: 140 191 0000 10748 0001 002 003 004 005 006085 086223 323 2000.

Just a start, do postback how thingsturned up or should you need additional information. Good luck andThank you for using FixYa.

SOURCE: Need wiring schematics for Haier HWR12XC5 AC

My friend ... you are doing a simple repair ... you don't need a wiring schematic to replace this power cord. When you get the unit open ... you will find the other end of the ripped cord ... black goes to black, white goes to white green goes to green or ground. In fact ... you will trim the end of the cord and reattach it using either crimp connectors or wire nuts.

Thanks for your interest in FixYa.com

Need code to turn tv on for haier model HTF20R21 tv?

Is it a Haier remote? Haier customer service person says that no Haier flat screen TVs or, for that matter, DVD players, are set up to be able to work with a universal remote; only their older tube TVs do. The Haier remote must be used. So we all can stop trying to find the codes. It wold have been nice is the user guides had revealed this unfortunate absence of functionality

Replacement on the Haier website is $19.99 plus a load in shipping.

I am not sure if your remote has a search code function, Most do. Check your instructions. I proceeded to go one by one through our remote's TV codes with the search code function, pushing the power switch after each code, until the set turned on.
Hope some of this helps

WHAT IS THE PORT UNDER THE HAIER 7 LCD THAT SAYs update HOW DO I USE THIS FEATURE WHAT IS IT USED FOR DOES THIS UPDATE THE TV ?????

This is a Star Trek GNDN USB mini port for the Haier factory to update the firmware (software stored permanently) in the TV.
If you return the set to Haier for servicing under the 90 days labor, 1 year parts warranty, Haier will probably just send you a refurbished unit.
Part of the refurbishment is for the Haier factory to update the software which runs this digital TV.
If you connect your computer to the port with the correct cable, nothing will happen.
No drivers or user mods (hacks) appear to be available.

Sound is operating correctly ..However, there isn't any video , screen has an extremely faint picture

Sounds like a broken backlight. That's a write-off for an old set, or a factory warranty repair (90 days labor, 1 year parts). First make sure the TV is in TV mode (press mode on the set, or TV/AV on the remote).
Once in TV mode, press MENU and use the navigation buttons (arrows and ENTER) to choose the set to factory default mode.
Also make sure you have a working signal by trying another TV on the antenna or cable coaxial wire.
You can also try adjusting the brightness from the MENU.
If these steps do not work, call the Haier hotline listed in the manual: 1-877-337-3639

The word "factory" is appearing 19"HAIER T.V.

Try www.xdiv.com/remotes


I found the GE 3 in 1 Model #RM24912 at Walmart for about $7 that worksperfectly. The booklet lists 5 codes for Haier, and code 0217 works allthe functions on my tv, including mute, channel return, and even themenu for color adjustment, sleep timer etc.
The code that I'm using is "0748", but try the codes provided - 1034 or 0768 and see what happens.

Codes
0081
0216
0217

If your remote is a 3 digit remote just drop the zero ie. 081, 216, 217

Hope it work's,




If all the other functions work on the tv remote, then turn the tv off,then un-plug it for 10 minutes. Plug it back in and turn it on. If theinput button still doesn't work then go into the tv menu and try and change it there.

Hope this works,

Nalin :)
