Thanks for using FixYa. As you have already replaced the Z-sus and the main logic board then the issue seems to be with the Y-main and/or Y-sus board. You’ll need to take the back off and check for any blown/bulged capacitors that might have gone bad and causing this issue. Please do accept the solution if the issue is resolved or post a comment for further assistance.

My LG 42PJ550 TV tries to switch on, but won't power up

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.

Sanyou DP26746 LCD TV Has sound, No picture, Has backlights, LCD is active

It sounds that the main digital board to your TV has damaged. But, before make it confirm, a through check should be done. Contact any experienced service technician for help. The work is skilled one, that a user cannot do it with ease.

guessing may or may not help---if the power board had bad caps you may have missed one that looks good and is not OR some other part on the board may be bad--my instinct in this case would be to consider replacement of the power board first if you cannot confirm every single voltage is coming out of it.

Have sound. But no picture

The Zsus and Ysus Board are common failures. It is a possibility that the Plasma Panel also is the problem. If you take the back off, (make sure unplug the set first), the board on your left is the Zsus and is marked accordingly. The Ysus is on the right of the Power supply. Look for fuses being open on the Zsus Board and Power Supply using a ohm meter. If they are, I would replace both Zsus and Ysus. They seen to fail together many times. If the fuses are good. I would suspect the Plasma Panel.
I hope this helps,

42 ilo plasma tv went pop no picture, but sound and all other settings work.

Most likely YSUS or ZSUS board. If you have any picture at all (very dark & cloudy) that would be the ZSUS. If no picture at all, then it is the YSUS. A secondary problem with these is that you generally have to replace the YSUS and Y-driver(s) at the same time.

Lg plasma 42PC3D no picture with sound

I know you already replaced the board, this is for future searchers. If you heard a popping sound, then the picture went out, there is a 32 pin Sanyo module that goes bad on the board. That's probably what caused the fuse to blow. Replace the module, then replace the fuse. The module is less than half the cost of a used board. Since this was a popular model TV, there are lots of replacement boards on the used market.
