Re: haier tv video problems
First of all you have to find out whether this unit has been upgraded with a new software or not?
If this unit is upgraded with new software either you have problem in Y-sus board or Z-sus board.
If this unit is having problem for the first time I would recommend to Change the Service Kit
Part number is TV-3940-01.
This kit contains E-prom,Y-sus board, Z-sus board and Control board you have to change these 3 boards together with E-prom IC.

Haier for sure recognizes the model. It's been a problem since produced. To correct the problem you'll need an upgrade kit. I'll attach the upgrade instructions and part number for the kit. Try resetting back to factory specs as noted at the bottom of instructions. Follow the procedure to a "T" when you see two menus pop up use the one on the right. Good luck! http://service.haieramerica.com/documents/SB-TV-0003.pdf
Had the same problem. Purchased Haier 42" model 42EP24S from Sears and it broke in 1 1/2 years. Couldn't find anyone to fix it so I ordered part Service Kit: TV-3940-01 from www.searspartsdirect.com the cost was $150.00. If your warranty is up and you're okay with doing your own work. :-)
Replaced 3 boards (instruction included) and my tv is back in action.
Harish.......If you've lost both audio and video you'll probably need the upgrade kit. If it were just video you could get by for sometime with replacing the slow blow fuse on the s-zus board. Check your eprom chip on the digiatal board to see if it appears burnt. If so it may have fried. If you'd like the service manual I'll need your email address
My experience with a Haier Plasma 42EP24S is that they have weak software chip that goes bad and can cause a number of symptoms from picture with no sound, will not recognize video inputs, or my current problem tv turns on and off irratically. This is the second time i have replace this chip, which is the socketed chip on the vga/component/dvi input circuit card. Last time i had this problem i ended up fixing it myself because sears took over 3 weeks and still could not figure out the problem. I am working on obtaining this chip, probally get about a dozen so if anyone thinks this may fix there problem as well i my have some for sale. email@example.com of Malobicky Digital Systems.
There is a easy fix - Most of you purchased your television at Sears or BrandsSmart Stores - No picture but you can hear sound - the part you need is the upgrade kit - part: TV-3940-01 - the part is not always available.
