When I turn the tv on it has a black screen, then after it warms up it is fine. When I change the channel after it warms up and is acting fine the problem starts all over again and I have to wait again to let it warm up on a different channel. Anyone know what is wrong?

Re: Tv needs to warm up?
I would suggest re-soldering your tuner connections and see if that helps. solder cracks tend to "fix" themselves after they warm up. Try the solder first but also look for evidence of a capacitor that may be swelled or leaking near the tuner.That is a possibility also.Hope this helps, let me know if you ned any further assistance.

started with different color pixels not coming in till the tv warmed up. Hadf to turn TV on and off several times before clear screen. Last night TV went black with a giant red x in the middle of screen. Now just 99% black.
Rca Screen ControlThese sets have screen control adjustment usually located behind the speaker grill(pops off -velcro or press tabs) and convergence front board. There are 6 contols on a black molded assembly about 31/2"x21/2" square. adjust only the top controls marked "Screen R G B" the bottom ones are focus Method: -turn on set and let warm up for 30 min at least -switch tv to blank unused video input channel -adjust each control in turn until you see the picture glow (with the corresponding color) and slightly back off the control - repeat for each color - this will increase screen brightness and ballance your color Hope this helped.
Most likely there are electrolytic capacitors in the power supply, video path, and scan amplifiers that are starting to fail from age. This is common in many of these sets. In consideration of the age of the set, this may not be worth having it serviced.
Sounds like you dlp lamp is going out. That's a pretty old TV and if you are still running on the stock lamp this is exactly the type of thing that will happen. The lamp model for this particular tv is the ty-la1001. You can find that over here:
Let me know when TV warms up does it go to standby? If yes, standby light would be blinking, let me know how many times it blinks? And if TV does not go to standby mode, does picture remain with red tone?
you can ask a good tv Technion man, since if it happens to be like that then in coming day u will have to face problems. So since this very common problem which will arise in old tv. Actually the real problem is that, some parts in the board may have become weak or the molded part in the board may have fallen down ,so changing that particular part or molding again may fix that problem. Since i am not an Technion I don't the right terms to help u.I have see this problem in many places and
don't worry your picture tube is well and good.
Check the voltage to the relay, usually 12v dc.
Also check the relay or replace as it may be stuck after the tv warms up. The micro chip for
functions could be locking up. Try spraying a
little freeze spray directly on chip after tv
is locked up see if this unlocks, if it does
you have a bad micro chip.
