Question about Mitsubishi CS-40503 TV

1 Answer

Entirely black screen Mitsubishi Model CS40503 SER. 530082

The screen is entirely black, no raster nothing; yet I feel static electricity when it is turned on. The audio works fine. Before the screen when blank, The screen had approximately 4 thin white HORIZONTAL lines spread vertically across the top 6 inches. If it is the CRT, is it worth replacing? I am on a fixed income. Today, is there such a thing as re-built CRT's? More than 50 years ago I replaced many CRT's with re-rebuilt. Now I art my age I would have my son help me if it is worth doing. How much should it cost if I take it to a shop. Labor? parts? I am in A SITUATION WHERE 50% OF THE COST WILL BE PAID BY ANOTHER ENTITY. THANK YOU SO MUCH. I love this TV and at my age, Big & bright is a necessity.

No picture, no menu, black screen, no raster, sound ok

From your detailed description, it sounds that the main chroma processor IC has damaged. Raster means nothing, but the lighted screen that appears, when a TV is switched ON. For some brands, there will be a blue screen; when there is no signal input, and some others will have a bright white screen with some snow.
I advice you to contact any service technician, to get this TV repaired. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy. Pull up older posts. Surf the site with patience. Do a search by type in the brand name of your device at its search box and press "Enter".

No display

You start as we all do at the begining. But where is that?
It's before you even remove the back cover. Being able to isolate the cause of the problem when you don't have a service manual and the only tool you have is a screwdriver to remove the back, is part of the secret of appliance servicing.
When you first switch on a set do you hear a one second hum.
If yes then the degaus is functioning and the ac power cord, on/off switch and fuse are all ok
Is the power led lit and do you get sound. Yes! then 5volt supply to
microprocessor is present, sound stage and power supply are all ok. Do you get a raster (brightness on screen). Yes ! then line driver, line output and frame stages are all ok. If no raster then run the back of your hand across the face of the screen, can you feel the static electricity. Yes, then EHT is present. Turn off the room lights and look through the ventillation holes of the rear cabinet, can you see the faint glow of the tube heaters. If no then you probably have dry joints on the tube base socket or on the flyback transformer. You've done all this and you haven't even taken the back of yet.

No picture but sound is good. Screen is black

Do you feel static electricity on the screen when you turn it on? If you do, you have vertical output failure. If you do not, then the likely failure is the high voltage power supply.
