Re: BATTERY BACKUP VS. SURGE SUPRESSOR FOR A KDF-60WF655
Rear projection TV's use a high power light bulb that is cooled by a fan. When you turn the TV off, the fan still runs for a little bit to cool the bulb off. A power outage is nothing short of jerking the plug out of the wall. This is murder on the bulbs because of all of the heat built up in them that the fan cannot remove. I would recomment a UPS (uninterupptable power supply) or as you refered to it "battery backup" to protect your investment. If there is a power outage, this will not really provide enough power to watch tv, but you can safely turn off the tv and it can cool down normally. Also, a UPS can filter and clean up "dirty" power, compensating for over and under voltages that could otherwise cause stress to your electronics. Check the power consumption of your tv, as UPS's are rated by their output capacity. Expect to pay $100 to $200 for a decent unit
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

This sounds possibly like a power related issue. If you are using a simple power strip to plug into, consider replacing it with an Uninterruptible Power Supply (aka Battery Backup, UPS). AC power related issues can cause screen waviness or shaking. Be sure to obtain the proper capacity unit for your needs. These units are rated in Volt AMPS and come in sizes from 300VA to 1500VA in the consumer product line. APC, Belkin, Triplite, CyberPower are some popular brands. The VA capacity to choose should be considered over price alone. Buying the cheapest one vs the right capacity can result in not having a unit capable of protecting your devices plugged into it. Understand these have 2 primary functions, 1. surge-protection 2. battery backup during a power related problem There are 2 different banks of receptacles on these units. 1. Some for surge protection AND battery backup 2. Some for surge protection ONLY Your computer would be plugged into the surge AND battery backup receptacles. When a power related incident occurs, the unit quickly switches the devices plugged into these receptacles off of AC power to the batteries, until the power issue is resolved. The time on battery is limited based on the VA capacity mentioned earlier in this solution. So buying the largest VA capacity unit you can afford will simply give you more available time on battery before the batteries are exhausted and must be recharged. On the other hand buying the smallest VA unit could result in an immediate and unexpected shut down of the computer if a power related issue occurs and the battery backup cannot handle the devices plugged into it. NEVER use these units for battery backup of Laser Printers or other high curent devices. These can destroy the battery backup. I hope this helps with your screen issue.
If tv turns back on itself after shut down then it is weak lamp problem, replace lamp in tv to fix its problem. Buy Sony original lamp for good picture in tv and replace it as it is user level repair and lamp replacement procedure is mentioned in related user manual. If standby light start blinking after shut down, let me know how many times it blinks after three second pause to provide you info about possible cause of problem. Thanks.
5 times red light blinks in Sony KDF-60WF655 shows problem with ballast supply that needs to be replaced. If you are handy with electronics stuff repair and have service manual copy then can replace it. Be Aware: electric shock risk is involve in TV repair. Or contact local TV tech to fix it. Need further help, let me know please. Thanks.
This TV is known for issues with the optical block(light engine) The discoloration is coming from the LCD panels in the light engine that have been damaged by the intense heat produced by the lamp. There is a class action lawsuit settlement between Sony and the New York state attorney general's office. Sony agreed to cover these problems going back 4 model years. if you had to pay for the repairs on this TV, you could expect to pay more than $1000 to replace the light engine. Call Sony customer relations at 1-800-222-SONY
and tell them you want this covered per the agreement I mentioned.
we had a repair guy come out and say that the ballast (power suply to the lamp) and the lamp was bad. ballast part # is 1-468-875-11 snd the lamps part # is A-1085-447-A. the retail price of both parts are $530.35 together. $195.07 for ballast and $300.58 for the lamp. with a little bit of research though you should be able to knock that down in half. he said that the ballast didn't have a chance to cool properly and is now acting in protection mode. he also said to plug it into the wall and not a surge protector. hope that was helpfull.
