Vizeo plasma tv takes several time to start then picture flickers badly for a minute or two. After this, the TV comes on and functions normally until turned off. What should I look for?

Good day!!!

That problem is usually cause of faulty capacitors on the power supply board..

Just follow this instruction to fix your TV..

1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter

Tv is on with no picture or sound, only 4 months old!!

The power supply regulator board to your set has the fault. If you try to open the set, or try to repair it by yourself, the warranty will void. The set must have warranty as it is new. Why do you spend for it? Just contact the nearest authorised service center for Sceptre. the components in this set will be very hard to get from open electronic spare part market, and will costly too.

It sounds like this is a problem with the inverter boards on the LCD panel. Unfortunately the inverter boards are usually only available with the whole LCD panel and the only way to fix it is by replacing the whole LCD panel. This is the most expensive part of the TV (about $1000) and you will need to take the whole TV apart in order to replace the panel. A new TV of similar make and model will usually be about the same price as the repair.

Should have been 3300 UF 10V caps that were bad? Shouls have been replaced with 3300UF 18V. 50V is huge. If it was replaced with a 50 the polarity may be wrong or the cap it too big to be seated property. Sometimes the caps just dry out and even a normal looking one will be the culprit of no OSD. Are you getting an LED fault code blinking? That should be a red led. Do you hear the relay clicking.? When you replaced the caps did you charge them? Just plugging in the set without trying to power it on for about 20-30 mins. I may be able to help you

Vizio, Model P4, manufactured in 2003 -- worked fine until 5 minutes ago

I have the same tv and the same problem. The power switch in the front flashes a bunch of times, but nothing else happens. Have you had any success in getting yours fixed?

RCA Scenium HDLP61W151

I had the same behavior, but not as a result of power outage. The TV is driven by windows CE software and it goes haywire every now and then. Usually pulling the plug for a few seconds takes care of any problems, but not this time (as you noticed). I had unplugged my ethernet connection on the TV a few weeks ago and thought I'd hook it up again to see if there was a new software release (not likely). I went to the menu and chose "Connections" and then chose "Ethernet Setup" and then chose "Reset All". After I closed the menu the TV rebooted itself (as it said it would). After my TV rebooted I had my analog channels back. There shouldn't be any connection between these two events, but it worked for me. Hopefully it will work for you as well. Good Luck!

Sylvania 6842-PEM Flickering Problem

Something is breaking down. Possibly a specific ceramic capacitor on the main power pcb that has been troublesome. Usually there is just a loud pop and the screen goes dead. If the set is less than a year old it is still on parts warranty and the technician could just change circuit boards until the problem is gone.
