SOURCE: blinking plasma tv

Hi alan,well any tv can be fixed but at what price,your fault sounds like a capacitor proberbly on the inverter board needs replacing,i have come across this problem quite a few times and it will take me 10-15 mins to diagnose and repair this type of problem and it is very inexpensive for the part.
Is the fault worse when the tv is first switched on from cold or does it get worse if the tv has been on for a while???
Hope this helps.

Sorry to say - it sounds like the 'pop of death' - If you got this from costco - give them a call and see if you can claim warranty (or the manufacturer).

Maxent MX42X3 42" plasma Monitor..


Are you sure that its the main A/Vboard coz it sounds like the main power supply issue to me. Anyways the mainboard is the large board usually located at the center of the tv. If you can remove the back cover of the tv and get me a high res picture of the tv I can mark the board for you.

I have a maxent 42 inch tv for the last 2-3 weeks the picture keeps blinking intermitentley last night while watching it we heard a pop and we have sound but no picture any answers


Plasma and LCD TV sets are prone to having capacitors in the power supply section fail. This is the most likely cause for the probem you describe. When capacitors fail your will commonly see one or more of the following symptoms.
  • No video, Power light is on or blinking.
  • TV is making a clicking noise.
  • TV takes a while to come on
  • Screen is very dim or flickers.

Again, You can get a power supply repair kit with the parts, detailed instructions, and support from sites such as www.TvRepairKits.com . Or just click here to see more details on their kit.

Here are pictures of capacitors...Notice that the ones below look bloated. They have failed and will need to be repalced.
