Having problems with your Standard (CRT) Televisions ?

I have a vizio vp422 that made a loud pop and now doesn't have any picture or sound. When you power it on the vizio display light turns from amber to white but that's it. U have to unplug it to turn it off. I have checked the fuses and they are good. The capacitors look good visually. There are a couple on the power supply board that have a black cover over the top, so I don't know about those. I changed the main board and made no difference. Someone please help!

Vizio VT470M no picture, no sound, no backlight. Power supply board looks good all voltages appear correct (24V, 5V, and 3.7V) and no "bulged" capacitors .

Vizio VP322. Replaced 3 bulging capacitors on power supply. TV worked great for about 2 days. Now it wont turn on. The Vizio is lit up orange on the bottom but thats it. If I unplug the wiring harness going to the input board the screen will light up black but goes back out as soon as plugged back in. If I unplug all but the AC power cord I get 5V off power supply on one and 200 on both VS and VA. I'm not detecting power at those when all harness are plugged back in.

My vizio p50hdm made a popping sound from the rear. Afterwards, the picture disappeared and tv screen was black (as if the power was off). Then within a minute the picture reappeared but looked real dull with a weird contrast. I disconnected power cord, turned off/on the tv, and the picture remains dull. Tv has been this way for almost a month. In order to repair, I have to pay an estimate of $600, including parts and labor. Please HELP!

Vizio VO370M will not power on. Vizio log stays yellow when power button pushed. Problem occurred following lightning storm, so suspecting the PS, but not certain. No physical damage apparent to either the PS or mainboard (fuse is good, no bulging/leaking caps, no burned spots, etc.). When testing PS, 5v connectors supply good 5.3v. 12v connectors have no power, but not certain if they always supply power or only when switched on. Is this more likely to be the PS or the mainboard?

I have a Vizio VP42 HDTV (inside says LG PDP42X3U400). One day I turned on the TV and heard a pop. I took off the back of the TV and inspected the main power supply board (P/N 6709900019A). Capictor C802 had totally blown up. The tv would not power on at all. I removed U801 and when plugging in the AC cord I heard two relays turn on and then back off after 1 to 2 seconds.
