Model # pt4298 i have no picture and sound

Disconnect all scart cables and see what happens if you change sources on the remote. If no response and still no pix or audio then it is likely that you have a power supply fault.
I hope I have been of help but please do not hesitate to ask if you have any further questions.
I appreciate your vote if you appreciate my reply.

What is the value of a resistor, location is RY801S. It is on the convergence board with a flyback. Akai projection TV model# PT4250A, thanks for listening!

I have a 50" Samsung DLP Rear-Projection HDTV that has the RY801S location number on my Power Board. The Power schematic shows a resistor with value 8.2M@1/2W

Burning smell and picture is distorted.

Projection sets have two very common problems.

The first common problem is convergence

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

My 42" rear projection tv wil not turn on worked fine yesterday came home today tried to turn it on and you can hear it click inside and then the red light under "timer" just blinks i was wondering what...

I was handed the same model the other day.You're Lucky it clicks. The one I have is completely dead. I will give you an idea to try. Unplug your TV set......for a few days. Find someone who has acess to a variac transformer....And see if your tv will come on at about 70 volts...Somewhere less than 90 volts. If it will powerup, you will need the powerline regulator replaced. Part# STR X6459. I will purchase one for the tv I have and see if this will correct my problem.

You will need to connect to a satellite or cable provider that will give you a signal box and remote to pick up digital signals and your favorite tv stations. Everything is turning digital.
