Question about Philips Televison & Video
I have a Philips Magnavox Model #7P6033 60 inch projection TV with chassis #PTV775-AH01 that was working perfectely until it just shut off. When the power button is pressed the green and red L.E.Ds come on momentarly then go out. A small chirp can be heard from the back of TV. But there is no picture or sound. I believe power supply is shuting down. I'm no TV repair man but can identify parts some what, and can replace parts if someone can tell me where to get them.
a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

Short in powersupply check secondary fuse and all other fuses too. Were there a color problem before this/ Because most of these set have convergence problems. The amps May need to be changed and resistors around them.

You can also check to see if you have bad fluid problems, by looking
down in your crt's with a flashlight when you unplug your set and see
if you can notice any particles that should not be there. Look at all
three and see if there is a difference. It should be clear, if not then
you need to change fluid and clean.
It sounds as if one of the picture elements (there are probably 3 for R-red G-green B-blue) has gone bad and it is most likely the green one. Sad to say it will probably cost you more to have it fixed than it would to buy a new TV. Most places will not even look at a TV for less than $85 or so, then they will add parts and labor... if they can even find parts.

Try checking some of the tunning and coupling capacitors around the horizontal section as well for some crystalized solder joints in that area.

That usually means a problem in the start up or deflection circuits. Diode, Horizontal ouput or driver transformer. What Chassis is this set, and I will be ableto give you some better information. Rca , GE and phillips need to be diagnosedwith the chassis number. Let me know the chassis.

I bought a crappy old magnavox and rebuilt it. I had both of these issues.
Since your tv is old, the blur problem is probably caused by old coolant in one or more of the CRT lens couplers. Hopefully, the lenses are simply out of alignment, but no one has ever worked on the tv, then this is unlikely.
First, unscrew the back panel of the tv console (should be a bunch of 1/4" hex head screws). There will then be a large white panel at a 45 degree angle held in place by two tabs or maybe even screws. Remove it to see the CRTs. A quick check for the blurry problem is to look directly into the CRTs while the tv is off. DO NOT do it while they are on if you can help it, as it is not good for your eyes.
Shine a white LED flashlight down into each of the CRT's top lenses. Avoid classic incandescent light in this case, since you will be looking for the difference between white and yellow. I you see a white plate inside, good. If the inside looks yellow, and has floating things in it, then the coolant fluid inside is old and bad. You can replace this, but it is a VERY delicate task and MUST be done in certain steps to avoid ruining the electronic boards anywhere within splash zone or drip reach of the lens couplers. The coolant is a special blend available at most tv repair shops, but it's basically clear antifreeze (which you wont likely find in an automotive store).
For the color being off, it is most likely the gain on each CRT being out of whack. First, change all of the user settings (in the on screen menu) for image, color, sharpness, etc to the middle or default.
With the back panel off, somewhere near the bottom of the inside there will be a small black plastic box with wires coming out the sides. This box should have 6 knobs on the front of it (the face facing the rear of the tv); 2 rows of red, green, and blue knobs. These are the screen controls for FOCUS and GAIN. And they should already have some sort of label telling you so.
I placed a mirror in front of my tv so I could see the screen as I adjusted, but you might be able to see it somewhat by hanging a sheet over the front of the screen and looking at it from the inside.
There's a much more in depth method to do this that is described in the service manual (which you are likely to have seen by now; they are usually either stapled to the back of the tv or hanging somewhere inside and easy to see)
But basically, just turn the knobs gently around until the picture looks about right to you. (Remember, if you turn them all up super bright, the CRT will not last very long. Try to keep the knobs near the middle of their turn ability)
If you want to do a full out overhaul of the screen, you'll have to make a lot of adjustments with a bunch of little knobs (variable resistors, really) on the computer board inside. The service manual will tell you what each one corresponds to, but most of them will have a subtle label on the board.
