    My TV will not power on but when you push the power the red light will come on and go back off. After you keep trying to power on about 20 times eventually it will come on. I have replaced the power supply twice.

Tv will not come on


I see so many here with no sound/nopicture issues:

ISSUES:

1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.6_17_2012_3_16_16_pm.jpg6_17_2012_3_16_36_pm.jpg

I am unable to adjust the red color in the convergence adjustment on my IQC50H94W 2000 Zenith 50". From everything I read I believe I need to replace my Convergence IC Chips, however I am not 100%...


Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.

I have a Zenith Projection 50" TV IQC50H94W that has a blue arc


You need to replace your STK392-150 I.C.'s, Also, check all of the large nearby resistors, make sure none are burned, and remember, you have to check the resistance out of circuit with a meter.

once the resistors are checked, and the convergence I.C.'s replaced, you should be able to converge the picture through the user menu.

Zenith DLP-Projection tv 42"


Try this solution which I found on Fixya

This solution is for the zenith 56" DLP. Unplug the tv, either from the wall socket or the TV. While the TV is unplugged hold the power button on the TV for 40 seconds. This lets the excessive power drain from the TV. If this does not work call 1-800-243-0000. This is the number for their help line. This is the fix the tech gave me and it worked right away. Hope this helps and have a great day.

Zenith IQC50H94W will not power up


First off, check Q655,EP98,and D756. If they all check good it may take a service manual to troubleshoot this set which is based on the Hitachi DP-05 chassis and is similar to their model 53FDX01B.
