I have a mitsubishi wd-62525 the power light keeps blinking, and i can't get picture. i unpluge it than want 2min than it stop blinking and i can turn to tv on and get a picture than after 30-40mi


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

I have a sony kdf 50e-2000 the green light goes on then it goes to thr red blinking lamp light. I have no sound or picture. If I replace the lamp light will I get sound and a picture again?


Hi,
Yes, if you have not replaced the lamp since you purchased this TV.
Lamps usually last about 6000 hours.
I've seen lamps last much longer than 6000Hrs, it all depends on the usage.
Remove the lamp from the TV and do a visual inspection, see if there's a crack on the glass or the bulb.
If the TV is few years old then the Lamp may be bad.

For a new Lamp: 800 638-3328

DO NOT BUY the lamp from ebay

Good luck to you.

Tv will not come on. Red light blinking on bottom left front. Red light blinks 7 times


I have the model Philips 37PF7320A/37 won't turn on and MOST articles on the Internet say it's the Capacitors capictors capictors..I checked all of them. My tv just blinked red lights, had the clicking sound at first power on, but then goes black. No sound. No picture. Nothing. Just blinking red lights.

MINE WAS RESISTOR no. 3318 , a 100 OHM RESISTOR ON POWER SUPPLY BOARD.

I BOUGHT REPLACEMENT FOR .99 CENTS SOLDER IT, AND EVERYTHING WORKED!!!

THAT WAS ALL IT TOOK.

JUST A SUGGESTION..
1. CHECK FOR BULGING CAPACITORS (90 PERCENT OF THE PROBLEM)
2. THEN CHECK FOR RESISTORS WITH MULTIMETER ( FALLS INTO THE OTHER 10 PERCENT OF THE PROBLEM.)

TELL ME IF THAT HELPS..normanw1@yahoo.comj

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.

Blinking powerlight on front when i try to turn on tv


This is more likely a power supply failure. Most causes of tv failure are due to bad capacitors on either a system board or the power supply. In this case, it sounds like the power supply. You can test the capacitors with a capacitor tester to determine faulty capacitor. You can also test other components like power supply current with voltmeter or mulit-tester.
