It is likey the blue lamp has failed. They are relatively cheap to replace and you can buy them online. There are dangerous voltages inside the cabinet. If you can see the lamps through any of the vents, you may be able to see the lamps. Check to see if blue or green are not working. There should be three separate lamps. Red Blue & Green. This is assuming the colour is like that on all sources. If it is only on one source, check the component cables in the back of the TV.
If the TV "seems to not have power" then I assume that no lights are on or blinking, and that no noise is made by the television at all. This is most likely a power supply issue or a power chip issue. If you know anyone who able to solder or has working knowledge of electronics boards this could be a relatively cheap fix ($30+ in parts). Otherwise, you may be paying hundreds from a TV repair shop.
Hi. This is an all too often occurrence. The TV's manufactured in the earlt to mid 1990s relied on an inferior set of capacitors in the power supply and mainboard components. They should have lasted about 25 to 30 years, but most are only lasting 5 or 6. The cheap capacitors pop, like a small balloon, or an overheated radiator, the capacitors contain an electrolyte gel, and this gel swells when induced with a charge. The cheap capacitors can split down the sides, boil over, or even pop the top off of them. If you look at the circuitry, you will see them standing up like small buttons, most with 3 wires coming out of the bouuton of them. Look to see if they have exploded like a battery, if, not, then your entire power supply is likely at fault.
Well lets figure out what a 57 inch would cost you in LCD over $1,000.00 right now and that is for a budget one or $450.00 plus warrenty on the part and repair that will last for years to come. See with me being inthe business for 20 plus years and now helping you out for FREE giving you my advice would be FIX it but find someone that will give you a better price you will be glad you did!!!
The problem is that your TV i isn't amplifying the right amount of current to make it wide. So the problem lie on the vertical amplifier. I strongly suggest that you let the technician do it because you might get electrocuted if you are not careful, it is more than 10,000 volts you know.
the rca itc222 will shut down for any of 25 different reason. the fact that u see a flashing light lets u know one thing it is not the main fuse. the most common reasons for shut down involve high voltage parts. In the shop we have a computer interface that let us diagnose much like error codes in a car. the d52w20 is a old version of the tic222 and average repair at my shop is 250 to 400 and if its the tubes then it wont be worth fixing. tubes run 250 apeacie and by the time labor is put in that can run as high as 1000. I SEE ALOT of these at shop. How are you with electronics. rember this set can hold a charge and can be dagerous
