Question about Televison & Video

1 Answer

Service shop They told me it's a power supply. I just noticed, that we communicate on two postings. The part # you gave me is right. I even have a picture that I can e-mail to you. I hate to change it and find it was a mistake.  Can the power supply be repaired?  I'm not trying to be cheap, but I'm tired to be fixing new things. It seems to be happening more often nowadays. THIS TV IS 2 YRS OLD AND A FEW DAYS AGO I GO TO TURN IT ON AND NOTHING HAPPENS.....NO POWER I HAVE CHECKED THE FUSE...IT'S FINE. ANY SUGESTIONS

The power supply can be repair, but many service techs rather not to, because they are switching power supplies and it can be a bit more difficult to fix them.
Many power supply components failed because they are expose to high heat generated internally when the TV is working, if the capacitors are working with temperatures of 170-185 degrees fahrenheit, their life expectancy is about 1000 to 1500 hours.

Hi plasma lg tv 42px4mvh-ta when i switch on it does's not switch on, i contacted technician the Guy told me that the main power supply board has a problem of suppling power how will you assist me


Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

2006 dodge sprinter key bent, need programer


Hi, I don't know about the Sprinter 2006 Truck.However, when I bought my Toyota Yaris recently I also only received one key. I told the supplier that when I trade in my car I gave them two keys and both were the auto open press button type. They eventually supplied me with a copy key without the auto open press button type. I was told to get one of these would cost ME $300. I can't afford that. However, I recently noticed in a shopping centre that the ..and I think it's the Minute Footwear Repairs while you wait people offer a reasonable supply service. But they are not everywhere. One MFR will be able to advise you which of their branch supply this service. Be careful using this sort of key as I also understand, that with WiFi these sorts of keys can be scanned easily, and you could have your car/truck stolen.
Good Luck.

Now i've noticed a crackling + no picture, but still great sound


This is something of an off brand model and about the only advice I have is if someone takes it apart---begin by a physical exam of plugs etc and then do some voltage checks in the power supply.

You might want to also GOOGLE the brand/model number to see if any parts are even available for it.

My guess is parts are slim or do not exist.

Is the power supply completely dead ? If so with this model of power supply its very common for the resistor 3318 on power supply to go out. Causing the power supply to completely die. Take out the resistor 3318 its a 470 Ohm 1W resistor. check it if it doesn't read around 430-530 Ohm Its gonna be bad ( most likely ith will read in the mega ohms. Replace with a 470 Ohm 2 W resistor. Also check power supply for cracks
