RCA TV RCA D61W20, Weird Problem

Hello, ive just fisnished repairing my TV, i had to replace the main board and seal the screen becouse it was leaking. When i receive the main board i tought the convergence grids where going to be programed for my TV but i end up buying a Template from Thompson and had to adjust the green grid from sratch.
Anyway everything works fine, except:

When i turn to a 1080 signal (wich my TV supports) the image on the top and bottom seem to look a little more darker, think of a letterbox effect but instead of cutting the image top and bottom its just darkens the image just a little bit, you can barely see the difference.
Now the weird thing abaout it is that when i use a 480 resolution it does not happend, the image looks fine and i have no problem.
Also, in 1080 mode, the image seems to to stretch upward when inside the darker part that i was talking abaout.

Do you have an idea how can i fix this?

Thanks.

Did you adjust the set in both modes 1080 and 480? They both need to be done seperately.

Vizio had problems with the processor boards.
If you had no lights, I would say power supply, Logo with lights, I would go with Processor board, check ebay. It is called a main board and they run about $60. That is what I would get, but then again, how old is it? If I could replace it with a new for $250 why take a chance for $60. I have pitched them before.http://www.ebay.com/sch/i.html?_odkw=E321VL+main+board&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR2.TRC1.A0.XE321VL+main+board+refurbished&_nkw=E321VL+main+board+refurbished&_sacat=0

Vizio E370VL Gray Screen no buttons work


This sounds like a problem with the main board in the TV. The main board is similar to the motherboard in a computer. You will need a professional to repair/order the parts. I would strongly recommend looking into purchasing a new TV rather than have this one repaired. In most cases the repair for a main board would be within a couple hundred dollars of a new set and often will not last very long.

This problems ur tv are having only can be two causes 1) The Y-Sustance main tuner logic board or 2)The tv Plasma screen panel itself it is slowly leaking radiaton and dying,if it is the tv plasma screen panel itself it is dying than the tv not worth repairing because by replacing the plasma screen panel itself will cost the same as a new tv itself.The Y-Sustance board-that the tuner main logic board that take in the tv incomming broadcasting signal cable.Tries websites like Shopjimmy.com,Ebay.com to buy a whole new refurbish Y-Sustance main tuner logic board for replacement.This tv problems are 50/50 between the Y-Sustance main tuner logic board or the very exspensive plasma screen panel itself.

Rear oil seal is leaking, what is the average repair cost for this. I have had several say over $200.00 or more. Is this true, I have a 06 Malibu LT with 118,000 miles


Hello if it is the rear main seal leaking oil, it would be much more than 200 dollars. the rear main seal replacement requires the transmission to be removed. this can cost as much as $1000.00

My KitchenAid Superba (whisper quiet ultima) started to leak out the front when it is running. Is this an easy repair or should we think of replacing the dishwasher? BTW - we love this dishwasher!


Hello. If the unit is over ten years old, I advise against repair. But if you do wish to consider repair, here are the things to look at

Main tub seal Note… If the main motor of your dishwasher is mounted vertically, beneath the center bottom of the dishwasher, the following instructions probably apply to you. But if your motor is mounted horizontally, the pump isn't serviceable--you need to replace the entire pump and motor assembly. The main tub seal is beneath the drain impeller. It prevents the water in the dishwasher from leaking out near the shaft of the motor. To get to the seal, which is inside the dishwasher, remove the: Lower rack Spray arm Spray arm support Wash/drain impellers Then pry the seal out of its housing and replace it. Door gasket or seal Over time, door gaskets and seals harden and lose their ability to seal properly. You can't repair the seals. You need to replace them if they've begun to leak. Water-inlet valve The water-inlet valve, itself, seldom leaks. But, the water-supply line from the house and the rubber tube leading from the valve to the inside of the dishwasher may leak. Tighten or repair/replace these as necessary. The water-inlet valve could mechanically stick open. When that happens, the water continues to flow into the dishwasher, which then floods your kitchen. Turn off the water supply to the dishwasher, and replace the valve. Hoses Behind the lower access panel on your dishwasher are several rubber or plastic hoses. If the leak appears at a connection, try a new clamp. If that doesn't work, replace the hose.

My neighbor has this problem...Their 60" vs60607 Mitsubishi Projection TV turns on and immediately turns off. The timer light blinks when this happens. I looked at the troubleshooting where other people...


My big screen had the same problem. According to my service repair person, the units have a latent defect in the lamp seals. Apparently, the lamps are encased in a silicone based oil. When the seals at the bottom of the lamp housing fail, the oil leaks onto the main circuit board and shorts out the system. The board woudl probably need to be repair or replaced. Again, according to my service person, the manufacturer corrected the design problem in subsequent models by installing a plastic shield across the circuit board.

No power up red light


The symptom you have should be addressed by a qualified -technician. However, the most common cause is either a convergence problem or fluid leaking onto the picture tube socket or the chassis. To check for a convergence problem remove the back of the TV. Typically on Akai the convergence board may be mounted above the chassis. Look for any big aluminum heat sink with a pair of large IC`s (STK-392-040) screwed to it. Mark and unplug the power connector to the board (the red molex connector). Plug the TV in and turn on the set. If the set comes on replace the convergence IC`s and check all the 3.9 ohm (orange,white, and gold stripes) resistors on the board. To check for a fluid leak remove the lower front panel of the set and look for any moisture on or around all three picture tube sockets and the main chassis. If there is moisture, it is necessary to repair or replace the seal, wash the board or chassis and repair any damage from corrosion.
