Question about Akai PT4298HD Rear Projection Television
Im having a red light on problem. There's no picture or sound of any kind. akia pt4298hd projection tv. Is there a code i can enter into the remote that will clear this condition? will replacing the power supply board repair this problem? what is the Samsung model number equivalent for Akia pt4298hd? What does the horizontal board look like? What does the convergence board look Like? Thanks any help will help. DVD MIKE
do me a favor, if the set is still together, please remove the back, and find the convergence card... it is on the upper right hand side. Unplug the RED plastic plug ONLY. Now try to turn on the TV. If it turns on, but the picture looks completely out of convergence, then yo uneed to replace the 2 STK392-040 IC's and you will have to test all of the 3.9 ohm resistors on the board. You will usually find 1 or 2 bad. let me know what you find.

Well you have to see whats going on first in order to enter a code!
You need ot start with the power supply unit then work yo way up from there.. I would call for estimates you never know.. The power supply is telling me it needs a new one.. That would be my best solutions then there maybe some minor things from there but yes look at the PSU first!!
