This might be a bad focus block/g2 block sometimes they go bad, they arent real easy to change out, but can be done.

Contrast really dark but seems to improve after the tv has been on several hours

Hi:
You may have a problem with the inverters in the unit, they are responsible for lighting up the back panel. Check or have checked the power supply voltage to the inverters, should be around 18-24 volts DC. Also leaky capacitors on the power supply will cause this issue as well as leaky or puffy capacitors on the inverter.

Colors are overlapping

Is it bowed top and bottow? One fix and a common problem with this set is there is a fuse right next to the flyback the seems to open because of broken solder joints. There is 3 off them and the middle one seems to blow all the time. Check the fuse with a meter and see if its open. If it is, follow the next set of directions.

To fix this, you will need to resolder the flyback and several other components. Then jump the fuse or replace it. I have personally done both but I don't like to jump the fuse because it defeats its purpose as a fuse.

You will need a T-20 and a T-10 screw driver to take the back off. The flyback with be on the left hand side of the set with a red wire coming off the top of it and the fuses will be located an inch or so to the right of the flyback. If you have schematics, sorry I don't know the designations of the components. Another problem, I have seen is on the right hand side of the set. There is a ribbon cable about 2 inches wide. The topside board(Convergence board). That connector is also known to go bad as well. Replace the connector.

I have a toshiba 65hm167 no red color on the screen

Your TV is a DLP one lamp does it all, not like the old projection TVs with the Red, Green & Blue CRTs. Your TV may have a bad light engine or lose cable connections.

Good luck
